What to Do When a Squirrel Has a Seizure

Do not touch it. The likely causes — head trauma, rodenticide, metabolic bone disease — and the exact call to make to get the animal real help.

Do not touch it. A seizing squirrel bites reflexively and has no awareness of doing so. What actually helps is a phone call to someone licensed to take it.

What to do, in order

  1. Keep people and pets back. Dogs in particular — a dog that mouths a rodenticide-poisoned squirrel takes a dose itself
  2. Do not handle the animal, not with gloves, not with a towel. Handling wild squirrels without a licence is an offence in most places, and the bite risk is real
  3. Reduce stimulation. Quiet, shade, no crowd. Noise and light prolong a seizure
  4. Note what you are seeing — the time it started, how long it lasted, whether the animal is circling, paddling, rigid or limp, and whether there is visible injury
  5. Call a licensed wildlife rehabilitator or your local animal control. Your state or regional wildlife agency keeps the list
  6. Follow their instructions exactly. If they ask you to contain the animal, they will tell you how, and they will usually bring equipment

If a dog or cat has been near it

Tell your vet, today. Secondary rodenticide poisoning is treatable when it is caught early and frequently fatal when it is not, and the window is short.

What is likely to be causing it

causewhat else you might see
Head traumaa fall or a road nearby; one-sided weakness; circling
Rodenticide poisoningslow and unafraid for days beforehand; bleeding from the nose or gums
Metabolic bone diseasehind-limb weakness, tremors; almost always a hand-raised animal
Heat strokehot weather, animal found in sun, panting
Severe dehydrationsunken eyes, skin that stays tented when lifted
Advanced infection or diseasepoor coat, thin, lesions

A bystander cannot reliably separate these, and does not need to. The useful contribution is an accurate description down the phone.

The hand-raised squirrel problem

Metabolic bone disease is worth understanding because it is entirely preventable and extremely common in squirrels people have raised at home.

Nuts and seeds are high in phosphorus and low in calcium. A growing squirrel fed on them alone draws calcium out of its own skeleton to keep blood levels up. The result is weak bones, fractures, tremors, hind-limb paralysis and eventually seizures.

It is the single strongest practical argument against raising a found kit at home: the diet that seems obvious — nuts, because squirrels eat nuts — is the one that causes it. Rehabilitators use formulated diets with a calcium source for exactly this reason.

If you find a kit, not an adult

Different situation, different answer.

  • Keep cats and dogs away
  • Place it in an open box at the base of the nearest tree, in shade
  • Add gentle warmth underneath — a bottle of warm water wrapped in cloth. A cold kit cannot digest and will not be retrieved
  • Withdraw and watch for two to three hours. Mothers routinely retrieve
  • Do not feed it. Cow’s milk and human formula cause fatal diarrhoea
  • Call a rehabilitator if nobody comes, or if it is cold, limp, bleeding, or has flies on it

Afterwards

If a squirrel dies in your garden, handle the carcass with gloves or an inverted bag, double-bag it, and wash your hands. Keep pets off it.

And if you see several sick or dead squirrels within a few weeks, report it to your state or regional wildlife agency before disposing of them. Clusters usually mean rodenticide somewhere nearby or a disease outbreak spreading at a feeding station, and both are things they track.

Common questions

What should I do if I see a squirrel having a seizure?

Do not touch it, and keep people and pets well away. A seizing animal is not aware of its surroundings and will bite reflexively, and a squirrel bite is a deep puncture that needs medical attention. Note what you are seeing and how long it lasts, keep the area quiet and shaded, and call a licensed wildlife rehabilitator or your local animal control. They are the people who can legally take it, and in most places handling a wild squirrel without a licence is an offence.

What causes seizures in squirrels?

The common causes are head trauma from a fall or a vehicle, secondary poisoning from rodenticide, and metabolic bone disease from a calcium-deficient diet — which is why it turns up so often in hand-raised squirrels fed nuts and seeds alone. Heat stroke, severe dehydration and advanced infection can all produce the same picture. A vet or rehabilitator can sometimes distinguish them; a bystander cannot.

Is a seizing squirrel dangerous to me?

It can bite without any awareness of doing so, and the incisors are long and sharp enough to cause a deep puncture wound. That is the real risk rather than disease, since squirrels are rarely implicated in rabies. Keep dogs away in particular — a dog that mouths a squirrel poisoned with rodenticide can take a dose of the poison itself.

Can a squirrel recover from a seizure?

Some do, depending on the cause. Head trauma can resolve with cage rest and supportive care, and metabolic bone disease responds to calcium correction when it is caught in time. Rodenticide poisoning has a specific treatment if it is identified early enough. None of those is possible without a rehabilitator or a vet, which is why the call matters more than anything a bystander can do on the spot.

Why do hand-raised squirrels get seizures?

Metabolic bone disease, caused by a diet of nuts and seeds with no calcium source. Nuts are high in phosphorus and low in calcium, so an animal raised on them pulls calcium out of its own skeleton, and the result is weak bones, tremors, paralysis and seizures. It is one of the strongest practical reasons not to attempt to raise a found kit at home — the diet that seems obvious is the one that causes it.

Should I give a seizing squirrel water or food?

No. An animal that is seizing or semi-conscious cannot swallow safely and will inhale whatever is put in its mouth. Offering food or water also means putting your hand near a mouth that is biting reflexively. Keep the area quiet, shaded and free of pets, and let a rehabilitator handle feeding and fluids.

What to Feed Deer in Winter: Mostly, Don't

Winter feeding kills more deer than it saves — their gut cannot digest grain in cold months. If you feed at all, browse and hay are the only safe options.
