How to Tell if a Squirrel is an Orphan

Orphan Squirrel.jpg

The best outcome for all wildlife is to be raised in its natural environment by its mother in the company of siblings. 

 If you find a baby, please leave it alone if it appears alert, is warm to the touch and appears healthy. Of course, if the baby is in imminent danger (in the street, near a cat, exposed to extreme weather or injured) you will need to collect even a healthy baby.   If you see other squirrels nearby or recently saw a squirrel carrying a baby in its mouth, the baby may have ventured out of the nest or dropped from its mother’s mouth while being relocated to an alternate nest site. A mother squirrel will usually attempt to take her young back if she perceives an opportunity to safely do so.   If the weather is mild, you can observe the baby from a distance and only retrieve it if the mother doesn’t collect it after a few hours.  

If the nest was recently disturbed, damaged or destroyed by weather, home repairs, tree trimming or removal, please allow the mother several hours of undisturbed time to return and move the babies. Some species of squirrels, such as the common urban eastern gray squirrel, maintain multiple nest sites and will relocate the babies if a site exists and she can safely do so. Please contact us for advice before intervening if you are unsure if a nest has been abandoned.  Of course, if you know the mother is dead or permanently removed, please collect the babies and contact a wildlife rehabilitator immediately.

When to Help

Intervention is recommended when the baby can be safely retrieved and:

  • The mother is dead or permanently removed

  • The baby in injured, cold, or appears sickly or unkempt

  • The baby is retrieved by a cat or other pet (even if no bite marks are evident)

  • A juvenile squirrel is following people or climbing up a leg

  • After warming the baby and placing it back where you found it, the mother has not retrieved it after a few hours of undisturbed and unseen observation

What to Look For

An infant with its eyes-closed (five week and under) who has lost its mother will likely be thirsty, hungry and suffering from exposure. If its mother has been gone more than 24 hours, the baby may have blindly wriggled out of the nest in search of her warmth and nourishment.

Most squirrels nest in hollows or drays (a big ball of leaves) located high in trees, so the initial fall may be from heights of 30 feet or greater. If the baby survives the fall, it may have sustained serious injuries. By the time the baby is found, it can be cold, injured, severely dehydrated, starving, stained in urine, and covered in filth, insects and/or larva.

Keep in mind, where one baby is found, others are likely nearby so check frequently over the next few hours and days for more orphans.  Squirrel litters range between two to eight young depending on the species.

Older orphaned babies with eyes-opened and fully furred (between 5 and 10 weeks of age) will often approach, follow, or even attempt to climb passer-bys when in distress. A healthy eyes-open baby who has been missing its mother for only hours rather than days will generally be more wary of people because it’s not yet desperate enough to approach a potential predator.

If a baby is wandering about trying to follow people, it’s most likely doing so not to be cute or social, but because needs help!  Baby squirrels rely on their mothers for a long time, weaning gradually from her between 8 and 12 weeks of age.  Fall born babies may spend the entire winter in the company of the mother and siblings.

If the baby is on its own prior to weaning, even though it is capable of moving about, it is still totally dependent on the care of its mother.

Unless the mother and siblings are observed nearby, a baby demonstrating this behavior is likely in need of help. Please collect it and contact a wildlife rehabilitator.

If You’re Still Not Sure…

​

If the weather is cold, and you suspect the baby may have been exposed to the elements for more than a few minutes, gently touch the baby to check if it feels cool to the touch. The mother won’t care if the baby smells of your scent but she wont retrieve it if its cold. For cold babies, alway warm the baby before placing it back where you found it by wrapping it loosely in a soft cloth and placing it next to a warm bottle wrapped in a towel. Conversely, if it’s an extremely hot day and the baby is in direct sunlight, provide some shade for the baby and place a cold bottle wrapped in a towel next to the baby to keep it cool. If the weather is not too cold or hot, and the baby is in a safe location, then leave the baby where it is.

Once you make sure the baby is not in any immediate danger, retreat a safe distance where you can observe without being seen by its mother. If the mother does not retrieve the baby after a couple of hours, then assume the baby has been orphaned and gently collect it.

For the safety of the mother, baby and pets, please move all pets indoors until the baby has been retrieved.

If the nest has been raided by predators, it is unlikely that a reunion with its mother will be possible – although you should try anyway. Predators are often attracted to unguarded nests of babies only when the mother has already gone missing. Mother squirrels are instinctually protective of their babies and when you find one that has not been recently cared for and protected, it usually means trouble for baby and its family.

Stabilizing & Transporting Wildlife

Squirrek Carrier Bag.webp

The instructions on this page are targeted towards transporting squirrels; however, they are appropriate for many other species of small mammals.

If you  have any concerns about how to safely transport a particular species of wildlife or are concerned about disease transmission, please discuss it with the rehabilitator before approaching the animal.

Squirrels, rabbits and opossums are not rabies vector species and are considered to be relatively low risk when handled properly. To learn how to do this, please read the warnings and steps below very carefully before attempting any care.

Warning!  

Always take extreme care to protect yourself, your family and pets.  Handling wildlife, particularly large carnivores or rabies vector species, can result in severe injury or death! Rabies vector species include bats, raccoons, fox, skunks and groundhogs.  Bats are currently the only known reservoir of rabies in Washington State.  It is estimated that no more than 1% of bats in nature are infected with rabies. Of the bats found on the ground 5 to 10% tested positive; therefore, it is recommended that you take extreme care if you choose to handle a bat on the ground.

Preparing an Orphan for Transport

1. Other than to treat life threatening injuries and provide supportive care, do not handle orphaned or injured wildlife.

2. Warm the baby and keep the baby warm.  If the baby is cool to the touch.  Carefully warm it before doing anything else!

3. Provide  older babies a comfortable place to hide.    Loosely wrap the baby in an old T-shirt or other soft fabric and place in a box in a quiet, dark, and warm location away from noise or other household activities.

4. Do not feed solid food or offer any milk or juice.  You may offer a small amount of water or  hydration fluid (such as  unflavored  Pedialyte) with  a dropper or syringe if the baby is clearly dehydrated.

5. For young babies (eyes closed), stimulate the baby to urinate and defecate as they cannot do it without assistance.

Capturing Injured Juvenile/Adult Wildlife

Adult squirrels can be very tricky to handle.  Use a heavy towel or blanket to loosely cover the animal. Handle wildlife with extreme care at your own risk!  Squirrels have very sharp incisors and strong jaw muscles. Adult squirrels can even bite through heavy leather gloves!

The bite of an angry squirrel is roughly  equivalent to having an ice pick stabbed into your hand  (usually repeatedly) until either the squirrel gets tired or you let go. Even then, it is likely you will need to gently pry the squirrel’s mouth open by placing firm pressure on both sides of the squirrel’s mouth to open the jaw. You must move quickly secure the squirrel in a towel or let it go by tossing it (yes, gently!) away from you before it latches on again.

Capture Technique

A squirrel has two defenses, the teeth and the claws.  When these are secured, the squirrel cannot inflict damage.  Severely injured squirrels are typically docile, but not always – always use good judgement.

1.   Drape a sturdy towel over the squirrel,  reach down and  feel for the head and shoulders. Through the towel, place your hand on each side of the head with you palm on the shoulders. Gently pick up the towel with the squirrel inside and wrap the towel around the squirrel into a ‘squirrel burrito’.  The towel can remain draped over the head but make sure the squirrel can breath.  Place burrito in box and secure top. Make sure air can get in the box.

2.  Place a towel in the bottom of a box and use a broom or other tool to very gently ‘sweep’ the squirrel into the box and secure the lid.  Make sure air can get in the box.

Only attempt to capture the animal if:

1. It can be done safely for the handler

2. It can be done safely for the animal

3. The handler has the tools necessary to restrain and hold the animal

4. The handler can provide constant observation and attention during and following the procedure.

Transporting the Animal​

  • Do not handle any wild animal if doing so risks your safety or the safety of others. If you are injured, you cannot help the animal. When in doubt, do not attempt to capture and wait for assistance from animal control or a wildlife rehabilitator.

  • Use a towel to cover the animal’s head to calm it down and reduce shock.

  • Do not handle or pet the wild animal, this just creates more stress and may lead to deeper shock.  Wild animals are not soothed the same way our domestic pets are by our touch or presence.   Consider how you would feel being petted by a grizzly bear that chased your down and proceeded to pat your head!  What looks like docility is more likely pure terror.

  • Keep a safe distance from the animal, and do what you can to protect it from harassment by pets and people (particularly curious children).

  • Wear gloves when handling all adults and eyes opened babies. Even though an adult can bite through them, they will provide some level of protection if loose enough that the squirrel is able to bite on an empty tip to keep him busy while he is transported to a cage or animal carrier. These will also protect from scratches.

  • Do not offer the animal food. You may offer water if it will be a while before you can transport the animal to a rehabilitator.

  • Prepare a well-ventilated, covered box of appropriate size by lining it with something absorbent, like newspaper or clean cloths (without holes or ragged or fringed edges). If you have no other alternative, wrap the animal in a towel or sweatshirt for immediate transport to a wildlife rehabilitation resource.  Note: Adult squirrels (possums, raccoons, bears…) will rapidly chew out of a cardboard box. This is particularly inconvenient when you are driving 60 MPH.

  • While waiting to transport the animal, place the box in a safe, quiet, dark place that is free from noise, kids, pets and human traffic. Place a heating pad, set on the lowest temperature, underneath half of the box, allowing room to move to a cooler or warmer spot as needed. If the driving distance is far, ensure the animal remains warm and comfortable during transport. Do not play the radio or conduct loud conversations.

  • Other than to treat life threatening injuries, do not attempt to treat the animal’s injuries. The best treatment possible is to leave the animal as is until it can be transported to a wildlife rehabilitation facility or veterinarian. Additional handling causes stress and improper treatment can cause further injury. One exception is if the animal is bleeding excessively. If this is the case, simply apply gentle pressure to the wound to stop the bleeding. Do not apply a tourniquet of any kind. Animals with amputated limbs are rarely releasable.

  • Wash your hands immediately after handling wildlife. Always practice good sanitation. Do not eat, smoke or drink while handling wildlife.  Even though baby animals are adorable in every way, resist the temptation to kiss them.  Especially baby raccoons! (Actually, we don’t recommend kissing adult raccoons either!)​

Do not attempt to rehabilitate the wild animal on your own. Each animal has unique care needs that are highly specific to its species.

Call a licensed wildlife rehabilitation facility to arrange to drop off the animal.

How to Warm a Baby Squirrel

Cold%2520Squirrel_edited_edited.jpg

Warm the baby immediately if it feels cool to the touch. If the baby is cold it must be treated for hypothermia, a condition where the animal’s core temperature falls below normal. This can happen quickly when an injured and/or naked baby is exposed to cold, wet or windy weather.

The normal body temperature for a gray squirrel is between 99° and 101° Fahrenheit (F) or 37.4° to 38.5° Celsius, and slightly higher for a fox squirrel. It is vital that the baby be warmed to at least 99° F before attempting to reunite it with its mother or administer any fluids.

Administering fluids or food to a cold baby, or providing inappropriate nutrition such as cows milk, juice, or human infant formula will result in death since a colder than normal core temperature slows or stops the digestive system resulting in the fluid rotting in the gut.

Inappropriate foods cannot digest properly to provide needed nutrition.  Rehabilitators often lose these babies because of the actions of well meaning people as soon as we warm them up.

Precautions

The most important point to remember is that you must take care to ensure the baby is not allowed to become overheated or burned – always use common sense and monitor the heat source.

In all cases were a heat source is placed in the box with the baby, there must be ample room for the baby to move away from the heat to a cooler spot.

It very simple: Don’t cook, squish, suffocate, or drown the baby!

Immediate (Temporary) Warming Methods

Some methods of heating are better than others, but do what you can with what you have readily available. The most effective methods surround the baby with gentle warmth, not just on one side.

  • Fan the baby with heat from a car heater, hair dryer or closely monitored heat lamp taking care not to overheat or burn the baby.

  • Wrap a microwavable heating pack in a towel and place it in the box with the baby or part way under the nest.

  • Fill a plastic bottle with hot water. Wrap it with a cloth and place it inside of the box with the baby. Ensure the bottle cannot roll on  or come in direct contact with the baby unless wrapped.

  • Fill a sock 2/3 full of rice and microwave on high for 2 to 2 ½ minutes. Carefully wrap the rice in a towel and place it in the box near the baby.  Take Care – the rice sock gets really hot!  Make sure the baby can move away from the heat.

  • While holding the baby at all times, immerse the baby in a bath of warm (not hot!) water, ensuring its head is above the water at all times. The baby must be completely dry afterwards.

  • In a pinch, warm the baby with your own body temperature by cupping it in warm hands or against your body – make sure it can breathe! Warning, only use this method with babies that have no fur or that you know do not have fleas, mites or other ectoparasites. These are typically easy to see by closely looking at the baby. Reference the link to debugging at the bottom of this page.

Warm%20Squirrel_edited.jpg

Keeping a Baby Warm

Whether the baby squirrel is kept inside a box or a cage, a constant heat source must be provided until the squirrel is fully furred and has reached at least 5 weeks of age (longer is better).

Once a cold baby squirrel is warmed, keep it warm to prevent hypothermia and death. Ideally, a furless baby squirrel will be kept in an environment that’s at a constant temperature of 100° F. A furred baby between 4 to 10 weeks will still be sensitive to cold; however, will do fine in temperatures between 96° to 98° degrees F.

If you have more than one baby, they will typically be able to maintain their body temperature by snuggling together in warm bedding, like fleece or cotton.

For more information on providing a suitable warm environment for the squirrel, follow the link to construct a makeshift incubator.

A warning about bugs!

Squirrels are relatively disease free animals and aren’t considered to be rabies vector species (see Zoonotic Diseases for more information); however, the insects that may live on and around them in nature can carry a variety of viral and bacterial agents that are best avoided!  For this reason, one of the first things most rehabilitators do once a baby is warm and stabilized is to ensure all ectoparasites are removed!   Please reference the Debugging Squirrels link for more information on how to safely accomplish this task!

Dispose of the nest!

You do not need to keep the squirrel nest; in fact, I recommend you immediately toss it outside in the trash UNLESS you plan to use it in your attempt to reunite the babies with its mom or place the nest back up in the tree.  It may contain a variety of vermin that you are not typically interested in rehabilitating and you certainly don’t want in your home.

 

How to Make a

Baby Squirrel Go Potty

Squirrel Potty.jpg

When you find an orphan, it almost always needs to eliminate (go potty or poop). In the wild, baby squirrels are stimulated to both urinate and defecate by their mother gently licking the genital area until the baby relieves itself. This also effectively keeps the baby’s bottom clean and healthy.

Since it is a rare individual who is willing to perform this task in the same fashion as the mom, you may use the method described here to accomplish the same outcome.

What is important to note is that you must simulate the baby to urinate and defecate every time you feed the baby. The baby cannot do it on its own until it is several weeks old (generally around the time it is fully furred at 5 to 6 weeks).

Even if you think the baby is urinating on its own because you see staining on its bedding does not mean it doesn’t need help. Failure to stimulate the baby regularly to empty its bladder and bowels will result in a painful death.

How to Stimulate the Baby to Eliminate

You will need cotton balls, squares or soft tissue and moderately warm (not hot) water. Taking a soft cotton ball or tissue, gently but rapidly stroke the genital area in a circular motion (the way you would expect a mother squirrel would do it).

The baby should produce urine within a few seconds but sometimes it takes a bit longer so be persistent. Soon you should see a yellow staining on the material or feel dampness. Keep it up until the baby stops urinating. Baby squirrels are stimulated to defecate the same way. Normally, the babies feces (poop) is very small, oblong, mild smelling and firm. If the feces looks and smells about the same as the food that went in the front end of baby, then the baby is not digesting the formula. If this occurs or at any time the infant develops diarrhea or bloating, cut back on the concentration of formula (dilute with water) until the situation clears up.

Reference the Recommended Reading links for more information on normal and abnormal feces.

Stimulating Squirrel for Potty Thumb.png

Adding a small amount of acidophilus powder (found in capsules or crushed tables available at most stores that supply vitamins) into the fluid helps prevent and resolve loose stools.

If diarrhea, bloating, constipation or problems getting the baby to urinate persist for more than 24 hours, the baby must receive immediate medical attention from a veterinarian with experience in wildlife rehabilitation.

Try introducing acidophilus at each feeding. It really works to prevent and resolve pale, loose, foul smelling and runny stools.

Babies may not urinate and produce feces every time they eat, but you should be able to accomplish the task frequently every day.

Stimulate the baby for at least two minutes after each feeding. Clean up the bottom with a scent free baby wipe or warm water on a clean cotton ball or tissue.

It is vital that the baby be kept clean, so frequently clean its bottom and be sure to clean out bedding when soiled.

 

 

How to Care for a Baby Squirrel

Learn everything you need to know about caring for the delicate needs of a baby squirrel. Even if you intend to care for the orphan on your own, be sure to reach out to licensed rehabilitator like the Squirrel Refuge for help.

how to feed a baby squirrel.jpg

The best outcome for any baby squirrel is to be raised by its mother, and barring that, to be reared in the company of other squirrels in a setting that best prepares it for a successful life in the wild. Squirrels rarely make good pets and in many jurisdictions it is illegal.  A single squirrel reared by humans is at a huge disadvantage for learning important social and survival skills. 

Before you proceed, ensure that you have followed the steps described in ‘I found a baby’ to address the orphan’s urgent needs.  You must never feed a cold baby and it must be fully hydrated before providing a formula appropriate for squirrels.  If you aren’t sure what species of squirrel you have, the link to the right can provide important clues to its identification.

 

Formula for Squirrels

What Formula to Feed Baby Squirrels.jpg

Squirrel Refuge recommends using Fox Valley Day One formula for squirrels.  For squirrels up to four weeks of age, the best formula is Fox Valley Day One 32/40 (appropriate for baby squirrels under four weeks, eastern cottontail, or baby opossum under 45 grams).  For squirrels over four weeks (or with eyes opened), Fox Valley Day One 20/50 is recommended.

Both products can be readily ordered directly from Fox Valley Animal Nutrition Inc. (800) 679-4666   http://foxvalleynutrition.com or from any of the squirrel rehabilitation supply online retailers listed. Alternatively, some rehabilitators feed their squirrels Zoologic Milk Matrix 33/40 By PetAg.

Preparing Formula

Combine 2 parts very hot water with one part Fox Valley formula and mix well.  After mixing, let formula rest for at least 20 minutes to cool and allow air bubbles to settle.  Refrigerate mixed formula for up to 48 hours.

Milk replacers for babies transitioning to formula or those with stool or digestive problems should be supplemented with a small amount of acidophilus (1/8 tsp) per ¼ cup mixed formula or plain yogurt.

If this is the first time you are offering formula to the baby, the baby must be fully hydrated and slowly transitioned onto full strength formula.    Reference transition instructions below.

Temporary Formula Substitutes

Depending on the degree of dehydration, the squirrel should initially be provided an infant rehydration formula such as Pedialyte® for at least the first twelve hours (more for severely dehydrated or emaciated babies!.)

Once fully hydrated, you may start to transition the baby over to an appropriate milk replacer. When transitioning from a hydration fluid to any formula, follow the same transition method as described in the Transitioning Formulas section below.

Since squirrel formula is generally not available in your local pet store and it will take a few days for the formula to arrive, the Squirrel Board (www.thesquirrelboard.com) recommends a temporary formula that may be fed in the interim.

Please note: this is not a nutritionally complete milk replacement formulation that can sustain an infant long term but is intended to be used as a temporary measure until the Fox Valley Formula arrives.

BABY SQUIRREL FEEDING FORMULAS

These are the only formulas we recommend, feeding anything other than these can kill your squirrel:

HOMEMADE GOAT’S MILK FORMULA – Day one – 2 weeks (INFANTS ONLY, NOT for older squirrels except as a temporary if powdered formulas are not available)

A great substitute formula only if you cannot get Esbilac Puppy Powder locally or have issues getting Fox Valley formula shipped. Also can be used if a baby has chronic diarrhea on commercial formula and for all squirrels up to 2 weeks old. This is a temporary formula and not to be used long term on squirrels over 2 weeks of age.

Formula

3 Tablespoons Meyenberg goat’s milk

2 Tablespoons Low Fat plain Stonyfield yogurt

1 Tablespoons heavy whipping cream

Formula will last 48 hours in refrigerator and then must be remade. Refrigerator should be 40 Degrees F or lower

Goats Milk can be purchased at natural food stores such as Trader Joe’s and Whole Foods, and at most health food stores that sell groceries. It must be goats milk made for human consumption. Do not substitute commercial goats milk formula made for baby goats or other livestock sold at feed stores.

Goat’s milk is available fresh in a carton (check exp date), evaporated in a can as a powdered milk. If you purchase either the evaporated or powdered versions, please blend them with hot water according to the package directions before using to make the formula.

Heavy Whipping Cream is found in small cartons in the grocery store near the coffee creamers and half and half. Regular heavy cream may be substituted if it is unavailable, but the heavy whipping cream has the highest fat content, and is preferred. You can also order and use Fox Valley Ultraboost from Amazon.

Yogurt has beneficial bacteria in it that soothes and settles digestion. Low fat yogurt is best, and a good choice that is very widely available is Stoneyfield Yobaby yogurt. However if it is unavailable, a low fat vanilla yogurt may be substituted. Avoid those that have artificial sweeteners in them.

NOTE: When Goat’s Milk formula is used, omit the heavy whipping cream for the first two weeks of life.

  • Fresh Goats Milk can be used instead of powdered. If you buy powdered do NOT use Esbilac brand powdered goats milk. Any powdered goats milk must be human grade like Meyenberg from Trader Joe’s/Whole Foods etc, not powdered goats milk for farm animals like you get from Tractor Supply. All fresh formula & Goats Milk must be refrigerated at 40 degrees or lower!
  • Keep refrigerated and discard after 48 hours and make fresh.
  • All formula changes should be slow transitions over the course of several days

Notes:

  • ALL powdered formulas, Fox Valley, Esbilac Powdered Puppy, Zoologic are 2 parts hot water to 1 part powdered formula, preparation info below with photos
  • For babies under 2 weeks we recommend homemade Goats Milk Formula or Esbilac Puppy Powder ONLY due to issues with Fox Valley 32/40 possible sitting like cement in tiny stomachs

 

POWDERED FORMULAS – FOX VALLEY & ESBILAC POWDERED PUPPY 

 Fox Valley: Available from Fox Valley or the Squirrel Store on our menu: Milk Replacers – Fox Valley Animal Nutrition, Inc.

Here is a breakdown of the formulas showing packaging:

ESBILAC PUPPY Puppy Milk Replacer POWDER (Day one thru weaning) – Quick & Easy to Find, this is MY personal go-to

Available from Petco, Petsmart, Rural King, Amazon, Vets and other pet suppliers

The easiest and quickest to obtain is Esbilac Puppy Powder with prebiotics and probiotics. This can be found in a can at Petco, Petsmart or Tractor Supply Etc. You can start on this formula for a pinky or furred squirrel (eyes closed) and used until weaning. After week 5 we recommend incrementally adding Fox Valley “Ultraboost” powder at 10% for ultimate weight gain. The can must look like this and contains powder, NOT liquid:

Tractor Supply 4health Supreme Puppy Milk Replacer

In the event you are unable to get Esbilac Puppy milk Replacer Powder and the only place nearby is Tractor Supply, a trusted rehabilitator has used this formula with great success. Protein / Fat content is listed as 33/40.

 

Fox Valley 32/40 (Week 2 through Week 5)

Fox Valley 32/40 and is intended for squirrels over 2 weeks unless carefully prepared and thoroughly dissolved. This powdered formula can be ordered from Amazon. Like Esbilac we recommend mixing 2 parts 32/40 powder with 1 part Ultraboost powder over 2 weeks. This is a HIGHER protein formula and Chis from Chris’s Squirrels & More states it can be used over 5 weeks provided you mix with 1/3 Ultraboost powder. Her contention is the higher protein is good for muscle growth and you add the extra fat in with the Ultraboost. \

FOX VALLEY 32/40 + Ultraboost 

This formula is for squirrels 4 – 5 weeks or older, fully furred and eyes open or about to open. This has a higher fat concentration but lower protein. Chris from Chris’s Squirrels and More recommends a higher protein level due to continued muscle growth and we agree. We prefer the 32/40 (after week 2) adding Ultraboost incrementally after week 5 starting at 10%, or Esbilac Puppy Powder adding Ultraboost in the same percentage. This formula is NOT recommended for baby squirrels under week 2 because of undissolved sediment. Proper preparation is paramount when using any formula especially Fox Valley.

 

 

FOR BULK REHABBERS – PetAg Zoologic Milk Matrix 33/40 (bulk premium formula)

This is the go-to for rehabilitators. At $153.90 for 5 lbs minimum this is cost prohibitive if you have just one squirrel. I recommend adding in Ultraboost incrementally after week five or transitioning (by blending) to Milk Matrix 30/52 PETAG Zoologic Milk Matrix 33/40 Milk Protein Powder for Wild & Exotic Non-Domestic Animals, 5-lb bag – Chewy.com

 

Transitioning Formula

Once the Fox Valley formula arrives, gently transition from the temporary formula to the full strength Fox Valley formula over six feedings.  This schedule helps the baby to slowly transition to the new formula without overly stressing its delicate digestive system.

  • First two feedings: Combine two parts Goat’s Milk Mixture to one Part Fox Valley Formula (2:1)

  • Second two feedings: Combine one part Goat’s Milk Mixture to one part Fox Valley Formula (1:1)

  • Last two feedings: Combine one part Goat’s Milk Mixture to two parts Fox Valley Formula (1:2)

  • Subsequent feedings: Feed full strength Fox Valley Formula

Using Emergency Formulas

for People, Puppies, and Kittens

Nonetheless, if nothing else is available, squirrels have survived on a commercial puppy milk replacement formula just fine.

Puppy milk replacer is always better than one made for kittens since their protein needs are much higher. Never use a milk replacer for human infants or cow’s milk.   See image to right.

Squirrels%20fed%20human%20formula_edited

The advantage of using a puppy formula is that it can be readily purchased at most pet stores; however, please note that there are disadvantages:

  • Many squirrels (especially very young ones) cannot tolerate a puppy formula and will succumb to diarrhea. This may be alleviated by adding a small amount of acidophilus powder or yogurt to the formula.

  • These formulation do not contain enough fat for proper weight gain. Adding supplemental heavy cream can help.

  • Puppy formulas are much more expensive than purchasing the Fox Valley formula online which is usually available for under $12 per pound, which is typically enough to feed an orphan through weaning.

How Much to Feed a Squirrel

Squirrel Feeding Position.jpg

The first 12 to 24 hours the baby should be fed only an electrolyte hydration formula, such as Pedialyte for infants.  Do not start feeding a baby until it is first warm, well hydrated, and has started to eliminate normally. Reference the links at the bottom of this page for more information on these topics.

If the baby has never had formula or is changing to a new brand, you must slowly introduce it over several feedings. Formula is never exactly like, or as good as, mother’s natural milk. The baby’s gastro- intestinal tract (gut) needs time to adjust to man-made formulas through slow introduction from the hydration fluid to full strength formula.   Reference the section entitled, “Transitioning to Formula” at the bottom of the Feeding Technique page (Link at bottom).

Figuring Out How Much to Feed

The ideal amount to feed the baby at each feeding is up to 5% of its body weight at an interval that closely matches the frequency the mother would feed her young in the wild. Below is a rough guide to the amount and schedule for feeding a baby based on its approximate age and size.

It is highly recommended that you purchase a gram scale to reduce overfeeding. Baby squirrels are notorious hogs and will happily overeat. Overeating may result in life threatening diarrhea and easy predation by cats, hawks and other menaces that prefer chubby slow moving prey.  Reference the link entitled, “Feeding complications” for more information.

If you don’t have a method of weighing the baby and are unsure of its age, you can roughly estimate it by comparing your squirrel to the ones pictured on the “How to determine the age of a baby squirrel” article (link to the right) available on the Chris’s Squirrels & More website.

The maximum amount should be no more than 5% in cc’s for the squirrel’s body weight in grams.

For example, if the squirrel weighs 100 grams (approximately 3.5 ounces), then 5% is 5 grams (.17 ounces) which translates to 5 cc (cubic centimeters)  or ml (milliliter) or (1 tsp) of formula.

Table 1: Feeding Amounts by Weight

Squirrel Feeding Amounts by Weight.png

Figuring Out How Frequently to Feed

​

How often you feed a baby squirrel the amounts listed above depends on their age.  Use Table 2 below to figure out how often to feed your babies based on their ages.

Here’s an example based on Table 1 below:

A squirrel weighing 100 grams should be fed  every 4 to 5 hours (reference Table 1 for squirrels weighing 120-160 grams) . The amount fed should be no more than of 5 cc (1/2 tsp*) of formula (reference Table  2  for amounts based on 100 grams of weight.

A note about frequency: It is ok to feed plus or minus 1/2 hour to accommodate scheduling for squirrels under 6 weeks. Older squirrels can be fed plus or minus 1 hour.

*Reference the Online Conversion Calculators  if converting grams (weight) or cc’s (volume) to other measuring systems.

Keeping Track of Feedings​

It’s important that the baby doesn’t get too much or too little formula to eat and that you know when it last eliminated (and if the product was normal – No blood in urine, loose or foul smelling stool!

Lack of normal appetite and abnormal bodily functions are important queues indicating a problem requiring immediate attention.

Keeping track can be especially hard when you have more than one care giver or multiple squirrels.

Our advice is, Write it down! Use our recommended daily care chart below.

If you are caring for multiple squirrels  you might notice that it can be hard to tell  who is who.

Consider using a temporary identification method such as  a non-toxic nail polish or permanent Sharpie marker on an

ear or the tummy. You may need to reapply every few days.

If the squirrels are furred and you only have a small number , another option is to clip a small notch of fur from the tail at different locations.

Tail fur only replaces itself once a year, so don’t go crazy with this by trimming a large quantity of fur.  Squirrels use their tails to communicate, for warmth, and balance.

Top Tips for the Safe Feeding of Squirrels

​

There are many things to consider for the proper feeding of baby squirrels, but here is a list of the top things you should know:

  • Do not add vitamins or minerals to any commercially prepared milk replacement product as they are already nutritionally complete.

  • Do not allow the baby to eat more than the recommended amount or frequency.

  • Never feed baby squirrels cow’s milk, fruit juice, Tang, Sunny D or any other sweet drink! Really, Never!

  • Never attempt to feed a cold baby! Baby should feel warm in your hands. Feeding a cold baby will kill it because it cannot digest the formula when cold.

  • Never feed a baby on its back or too fast. Use a 1cc syringe on small babies to control the feed rate. Baby squirrels easily aspirate and choke.

  • Always stimulate the baby to urinate after feeding! An ‘eyes closed baby’ cannot eliminate without stimulation and will suffer a painful death without help.

  • Normal formula fed baby squirrel feces ranges from yellow to dark golden colored and is well formed like small seeds. If the stool becomes loose, smelly, watery, white or very pale then cut back on the concentration of formula or provide pedialyte for a few feedings until the feces is normal again. Adding a small amount of acidophilus or yogurt to the formula helps to keep the baby regular.

 

5 Common Feeding

Complications in Squirrels

Squirrel%20Bloat_edited.jpg

The most common cause of health problems related to the gastro intestinal tract in babies is improper feeding or diet. That is not to say that illnesses such as diarrhea do not result from other problems. All information on this website is provided for reference only. We are not licensed veterinarians! Please discuss all diagnosis and treatment options with your veterinarian or other wildlife resource.

Many new rehabilitators make common mistakes that can cost the life of a baby squirrel. If you are new to syringe feeding baby squirrels, please review the Feeding Technique Page and the recommended readings.

#1 Aspiration

Aspiration occurs when the baby inhales fluid into the lungs during feeding. Signs of aspiration include bubbling fluid from the mouth or nose. In a normal baby, this can occur when the formula is allowed to flow too quickly into the baby’s mouth.

To reduce the risk of aspiration:

  • Avoid using a pet nurser bottle with a nipple that flows freely when inverted. Instead, attach a nipple to a smaller syringe that allows you to control the rate of flow. The size of the nipple hole is correct when the formula drips out when inverted.

  • Always feed the baby in an upright position in warm conditions with good lighting so that you can monitor the squirrel’s swallowing reflex.

Permitting the baby to breathe fluid into the lungs may result in a bacterial infection that can rapidly progress into

a life threatening condition called ‘Aspiration Pneumonia.’

Symptoms of Aspiration Pneumonia are:

  • Audible breathing or a ‘clicking sound’ in the lungs

  • Open mouth or labored breathing

  • A runny or congested nose

  • General malaise with minimal interest in feeding

  • Death

What to Do If a Baby Aspirates

If the baby does aspirate fluids, pull the nipple away from the mouth, hold the baby in both hands face down and quickly by gently tip the baby forward and down to help gravity drain the fluid from the nose and lungs. Blot fluid from the nostrils and mouth. When the baby is calm and the airways are clear, resume feeding.  If the baby shows any signs of illness contact your vet or wildlife resource immediately.

#2 Bloat

Bloat usually is the result of over feeding, feeding a cold baby, or feeding an improper diet.  Never feed a cold baby or offer any of the following foods: Cow’s milk, fruit Juice or sugary drinks, Diet or alcoholic beverages, or solid foods (even baby food) to a squirrel under 7 weeks old.

To help resolve the issue, feed the baby a hydration fluid safe for infants, such as pedialyte until the problem resolves. If the proper persists, contact a wildlife rehabilitator or your vet.

Some success has been achieved by administering human baby gas drops (simethicone), warmth and gentle massage. Of course, prevention is the best course. Don’t feed a cold baby or  more than 5% of its body weight, use proper formula and follow all mixing instructions to the letter. Always, stimulate a baby under five weeks to eliminate after each feeding.

#3 Diarrhea

Healthy babies eliminate urine and feces several times a day when stimulated. Normal feces are firm and light colored. If the stool appears non-formed, loose, runny, or foul smelling, something is not right in baby’s gut. This can occur with the baby is not properly transitioned to a new formula, fed the wrong formula, fed too frequently, or fed too much at feeding and ‘over extending’ the stomach.

To correct, switch the baby back to an electrolyte hydration formula such as baby pedialyte or lactated ringers (with no more than 2.5% lactose) for a few feedings and then from the schedule to transition the baby back onto formula. If problems continue, the baby should be seen by a vet.

#4 Dehydration

Baby squirrels can dehydrate in just a few hours without the care of their mother or the safety of the nest, particularly on a warm day. On intake, most neonates arrive with some degree of dehydration.

Physical signs of dehydration are sunken eyes, overly wrinkly and/or dry skin (some wrinkles and loose skin is normal), lethargy, hypothermia, dark or hard feces, dark urine (if any), dry mucous membranes, pale gums, and signs of shock. It’s best to assume that the baby is at least 5% dehydrated on intake. After warming the baby, provide immediate warm appropriate hydration fluids.

#5 Genital Nursing

Severe and life threatening injuries can be done when a squirrel (or one of its littermates) mistakes a penis for a nipple. This is not sexual for your squirrel. The squirrel (or one of his littermates) is either not being fed frequently enough or not fed a proper diet. Correct the diet by only feeding a formula appropriate for squirrels and treat the penis with ophthalmologic antibiotics and YUK anti-lick gel.  Genital nursing usually occurs on male squirrels but can also affect females.

Genital nursing is a very common problem that can rapidly become life threatening if the urethra is blocked due to swelling or scabbing such that the squirrel can no longer urinate. Check all squirrels at each feeding for signs of redness at the tip of the genitals, swelling or elongation of the genitals, dark purple sores, discharge or scabbing. Move quickly to separate out any squirrel that shows signs of genital nursing. Even moderate cases can require a Vet’s care to mitigate permanent damage that may require the squirrel be humanely euthanized.

To treat the injury, gently soak off any scabs that may be preventing the squirrel from urinating with a warm wet cotton ball and gently stimulate the squirrel to eliminate.   If you are unable to get the squirrel to urinate for 24 hours, take the squirrel immediately to a veterinarian.

Some squirrels will not be deterred by the foul taste of an anti-lick gel and must be separated from other squirrels until they are old enough to fend off the overly oral squirrel.

Topical Antibiotic Use in Squirrels

For small babies that are unlikely to lick at the wound site, a standard triple antibiotic ointment such as Neosporin can be applied to the penis.  Older babies (with their eyes open) will generally lick at the wound and ingest the ointment, which can seriously imbalance their digestive system and result in life threatening diarrhea.  Instead, use Neo PolyDex or another ophthalmic ointment where a topical antibiotic is indicated.  Also, treat the genital area with an anti lick gel to discourage further damage.
