How to Feed a Baby Squirrel (& What They Can Eat)

First Things First: Does the Baby Squirrel Actually Need Help?

Not every baby squirrel on the ground is orphaned. Squirrel mothers move babies, rebuild nests, and retrieve young after storms. In many cases, the best rescuer is Mom, not you. If the baby is warm, active, uninjured, and found near the nesting tree, reunion is often the ideal outcome.

Signs the baby may need rescue

• It is cold, wet, weak, or barely moving.
• It has an obvious wound, swelling, or broken limb.
• It has been in a cat’s or dog’s mouth.
• It is covered in fly eggs or insects.
• It cries nonstop for hours and no mother returns.
• Its eyes are closed and it is alone outside the nest for a long time.

Try reunion if the baby seems otherwise healthy

If the squirrel is not visibly injured, place it in a shallow box lined with soft cloth near the base of the tree where it was found. Keep it warm, but do not overheat it. Then step well back and watch from a distance. A mother squirrel will not appreciate an audience hovering like an overexcited sports commentator.

If the mother returns and carries the baby away, excellent. If not, or if dusk arrives with no reunion, contact a licensed wildlife rehabilitator right away. In the United States, that is the gold standard. Wildlife care is specialized, and in many places, only permitted rehabilitators are legally allowed to keep and treat wild squirrels.

Before You Feed Anything: Warm the Baby First

A cold baby squirrel should not be fed. This is one of the biggest rules in wildlife care, and for good reason. A chilled squirrel cannot digest properly and is at higher risk of aspiration, bloating, or worse. If the baby feels cool, warm it gradually before you even think about formula.

Use a small box or carrier lined with fleece, a soft T-shirt, or another non-raveling fabric. Add a gentle heat source under half the box, such as a heating pad on low with layers between the pad and the baby, or a warm water bottle wrapped in cloth. The baby should be able to move away from the heat if it gets too warm.

Keep the box in a quiet, dark place away from kids, pets, and household chaos. A baby squirrel does not need a social calendar. It needs calm, warmth, and professional help.

How to Feed a Baby Squirrel Safely

If a wildlife rehabilitator tells you to provide temporary care until transfer, follow their instructions as closely as possible. The details can vary based on the squirrel’s age, hydration, injuries, and overall condition. Still, the basic feeding principles stay pretty consistent.

Step 1: Rehydrate before offering formula

Dehydrated babies are often given a warmed electrolyte solution first rather than immediate full-strength formula. This is bridge care, not the final diet. A severely dehydrated or injured squirrel needs a rehabilitator or veterinarian, not a kitchen experiment and good intentions.

Step 2: Use the right kind of milk replacer

Baby squirrels do not do well on cow’s milk. They also should not be fed random pet milk, human infant formula, condensed milk, or a “close enough” substitute from the back of the fridge. Wildlife rehabilitators commonly use squirrel-appropriate or wildlife-approved milk replacers. Brands often mentioned by squirrel specialists include Fox Valley and Wombaroo, and some rescuers use a high-quality puppy milk replacer only as a short-term stopgap until proper formula is available.

Step 3: Feed slowly with a small syringe

A small syringe gives more control than a bottle. That matters because baby squirrels can aspirate easily if liquid flows too fast. Hold the baby in a natural nursing posture, belly-down or upright, never on its back like a human infant. Go slowly. Really slowly. Slow enough that your impatient side starts checking the clock.

Step 4: Watch for danger signs while feeding

Stop immediately if milk bubbles from the nose, the baby coughs, clicks, or struggles to breathe. Those are red flags for aspiration. The squirrel needs expert help right away.

Step 5: Very young babies may need stimulation

Neonatal squirrels may need help urinating and passing stool after feeding, usually with gentle stimulation using a warm, damp tissue. This is normal for very young orphaned mammals, but it is another reason professional guidance matters. Tiny babies have tiny margins for error.

What Can a Baby Squirrel Eat?

The answer depends heavily on the squirrel’s age. A baby with closed eyes has a very different menu from a weaning juvenile. Offering solid food too early is like handing a steak to a newborn. Bold move. Bad move.

Newborn to eyes-open stage

Best food: species-appropriate formula or wildlife-approved milk replacer only.

At this stage, the squirrel’s digestive system is built for milk. No nuts, seeds, fruit, bread, peanut butter, or vegetables. Not even as a “just a little taste” situation.

Eyes-open, early weaning stage

Best foods: formula remains the foundation, while solids are introduced gradually.

As babies mature, squirrel specialists often introduce a high-quality rodent block or squirrel block first, then add healthy vegetables and safe natural browse. This matters because a squirrel raised on sugary fruit and fatty nuts can become a picky eater with poor calcium balance. Cute? Yes. Nutritionally ideal? Not even close.

Weaning and juvenile stage

Best foods: formula plus structured solid foods.

At this point, a young squirrel may begin nibbling more confidently. Appropriate options can include:

• Rodent blocks or squirrel blocks designed for balanced nutrition
• Leafy greens and selected vegetables
• Safe twigs, branches, and wild foods from unsprayed areas
• Clean water, once the squirrel is developmentally ready and already taking solids well

Nuts and fruit should be limited, especially early in weaning. In the human imagination, squirrels live on a glamorous all-nut buffet. In reality, that kind of diet can create nutritional trouble fast.

Best Foods for Weaning Baby Squirrels

If a rehabilitator confirms the squirrel is old enough for solids, focus on nutrition before treats. Good starter foods often include:

• Rodent or squirrel blocks: Often recommended as the first solid because they support balanced vitamins and minerals, especially calcium.
• Leafy greens: Romaine, watercress, bok choy, arugula, and other safe greens are often used.
• Cruciferous vegetables: Small amounts of broccoli, cabbage, or Brussels sprouts may be offered depending on the rehab plan.
• Natural browse: Safe branches, buds, leaves, and wild plant material can help young squirrels practice normal chewing and foraging behaviors.

The goal is not just to fill the squirrel up. It is to build a strong, release-ready body with healthy bones, teeth, and natural feeding habits.

What Baby Squirrels Should Not Eat

This list is where many well-meaning rescuers get into trouble. Foods that seem harmless can cause diarrhea, malnutrition, aspiration, or metabolic bone disease.

• Cow’s milk
• Human baby formula
• Bread, crackers, cereal, or junk food
• Peanut butter for young babies
• Nuts and seeds as a main diet
• Large amounts of fruit
• Sweetened drinks
• Food offered while the baby is cold, weak, or lying on its back

One of the biggest myths is that squirrels should be started on nuts right away. In truth, leading with nuts is like letting a toddler design their own grocery list. The results may be enthusiastic, but they will not be balanced.

Common Feeding Mistakes to Avoid

Feeding too soon

A cold or dehydrated squirrel needs stabilization first.

Feeding too fast

Aspiration is one of the biggest risks in orphan squirrel care. Slow and controlled is the rule.

Using the wrong posture

Never feed a baby squirrel on its back. Natural nursing position only.

Weaning too early

Young squirrels often need formula longer than people assume. A squirrel that nibbles is not always a squirrel that is ready to go fully milk-free.

Making fruit and nuts the main event

They are treats, not the nutritional backbone of a baby squirrel’s diet.

Trying to raise the squirrel without expert help

Even when a squirrel seems to improve, rehab is about more than survival. Proper release requires species-appropriate diet, housing, reduced human imprinting, climbing practice, and outdoor conditioning.

When to Call a Wildlife Rehabilitator Immediately

Call without delay if the baby squirrel:

• Is bleeding or has a visible injury
• Has been caught by a cat or dog
• Is limp, cold, or unresponsive
• Has fly eggs, maggots, or severe dehydration
• Shows trouble breathing or milk from the nose
• Is a newborn with no nest and no mother returning

If you are in the United States, wildlife hotlines, state agencies, and directories like Animal Help Now can help you locate a licensed rehabilitator quickly. That call can make the difference between a temporary rescue and a lasting tragedy.

Quick FAQ

Can baby squirrels drink water?

Not as a substitute for proper rehydration or formula care. Very young babies need specialized support, and plain water can be the wrong first step if they are weak or chilled.

Can I feed a baby squirrel kitten formula?

It is not the preferred standard. Wildlife rehabilitators generally rely on more appropriate milk replacers for squirrels. Use only what a professional recommends.

Can a baby squirrel eat bananas, apples, or peanuts?

Older juveniles may sample limited fruit or nuts later in development, but those foods should not be the starting diet for a baby squirrel. Early nutrition should be structured and calcium-conscious.

How long can a baby squirrel go without food?

Not long if it is truly orphaned, but feeding the wrong thing at the wrong time can be worse than waiting a little while to get expert guidance. Warmth and rapid rehab contact come first.

Final Takeaway

If you remember only one thing, remember this: feed a baby squirrel only after it is warm and only with the right formula and technique. For newborns and very young babies, formula is the correct food. For weaning squirrels, balanced solids like rodent blocks and healthy vegetables matter more than nuts and fruit. And for every stage, a licensed wildlife rehabilitator is your best partner.

Baby squirrels are fragile, fast-changing little creatures, and the internet is full of advice that ranges from helpful to absolutely bananas. The safest path is simple: warm the baby, try reunion when appropriate, avoid improvising with household foods, and get expert help quickly. That combination gives the squirrel its best chance of going back where it belongs: up a tree, judging everyone from a branch.

Real-World Rescue Experiences and Lessons from Baby Squirrel Care

Across wildlife centers and rescue stories, the same pattern shows up again and again. A storm rolls through, a tree gets trimmed at the wrong time, or a curious pet finds a nest before a person does. The baby squirrel is discovered on the ground, and the finder faces a rush of conflicting emotions: panic, sympathy, and an immediate desire to “feed it something.” That instinct is understandable. It is also where many rescues go off course.

One common lesson from rehabilitators is that warmth changes everything. Finders often assume a crying baby is starving, but rehab teams routinely explain that the baby is just as likely to be cold, shocked, or dehydrated. Once warmed and placed properly for a reunion attempt, some babies are picked up by their mothers within hours. That outcome teaches a powerful truth: rescue does not always mean raising; sometimes it means stepping back at the right moment.

Another frequent experience involves wrong milk. People mean well, but cow’s milk, random formula, or overly rich homemade mixtures can leave a baby squirrel bloated, weak, or aspirating. Wildlife organizations have shared cases where a baby survived the fall from the nest but nearly did not survive the “help.” That sounds harsh, yet it is valuable. Good rescue is often less about doing more and more about doing the right few things well.

Rehabilitators also talk about how feeding technique matters just as much as food choice. A baby squirrel fed too quickly can inhale liquid into the lungs. That is why professionals favor slow syringe feeding, natural body position, and careful observation. To an outsider, the process can look fussy. To a rehabber, it is simply the difference between nourishment and emergency.

There are also longer-term lessons from squirrels that make it past the crisis stage. Young squirrels that start solids on balanced foods tend to do better than squirrels spoiled early on nuts and sweet fruit. It turns out that even tiny wildlife can become little junk-food enthusiasts. Cute in theory, not cute when bone health suffers. That is why experienced caretakers put nutrition ahead of charm and choose calcium-conscious foods before treats.

Perhaps the biggest lesson of all is that successful squirrel care is a team effort. The finder provides quick action, warmth, and safe containment. The rehabilitator brings species knowledge, feeding skill, medical judgment, and release planning. When those pieces come together, the story usually ends the way everyone wants: not with a squirrel staying indoors forever, but with a healthy youngster climbing, foraging, and returning to wild squirrel business. Which, judging by their energy, appears to be 40 percent acrobatics and 60 percent mild chaos.
