Cat Seizures

Seeing your cat have a seizure can be frightening. Because cats often hide illness and may have subtle focal seizures, any seizure-like episode is worth prompt veterinary attention, and this page explains common causes, what to do right away, and when to seek emergency care.

When to Call a Vet for Cat Seizures

Emergency

Go to the ER now

● Your cat is actively seizing now, especially if the seizure lasts more than 3 to 5 minutes.
● Your cat has repeated seizures close together, including seizures less than 10 to 15 minutes apart or more than one seizure in 24 hours.
● Your cat does not recover normally after a seizure, seems unconscious, has trouble breathing, or remains severely disoriented.
● This is your cat’s first known seizure, especially in a kitten, senior cat, or cat with diabetes, kidney disease, liver disease, or recent head trauma.
● You suspect toxin exposure, such as flea or tick products not labeled for cats, human medication, illicit drugs, or chemicals.

Urgent

See a vet within 24 hours

● Your cat had a brief seizure but now seems stable and alert.
● Your cat has twitching, facial movements, drooling, sudden staring, or collapse that may represent a focal seizure.
● Your cat is acting abnormal after the episode, including pacing, hiding, temporary blindness, confusion, or unusual vocalizing.
● Your cat has a known seizure disorder but the episodes are becoming more frequent, longer, or more intense.
● Your cat had a seizure recently and has not yet been examined by a veterinarian.

Monitor

Watch at home, call if it worsens

● There are very few situations where seizure-like episodes should only be monitored at home without veterinary input.
● If your cat has a diagnosed seizure disorder and your veterinarian has given a home plan, follow that plan closely and keep a seizure log.
● Record the date, time, duration, what the episode looked like, and how your cat behaved before and after it.
● Take a video if you can do so safely, since feline seizures can be subtle and easy to miss.
● Even if your cat seems normal afterward, contact your veterinarian for guidance because cats often hide serious illness.

Common Causes of Cat Seizures

🧠

Brain disease

Seizures in cats are often linked to disease affecting the brain itself, including inflammation, structural abnormalities, or epilepsy. Idiopathic epilepsy can occur, but compared with dogs, cats more often have an underlying brain problem.

🎗️

Brain tumors

In older cats, brain tumors such as meningioma are an important cause of seizures. These cats may also show behavior changes, circling, balance problems, or other neurologic signs.

🦠

Infections

Infectious diseases can affect the brain and trigger seizures. Examples reported by veterinary sources include feline infectious peritonitis and infections that extend from the middle or inner ear.

☠️

Toxins or medication exposure

Poisoning is a major concern, especially with human medications, inappropriate flea products, and other toxins. If you suspect exposure, call your vet or a pet poison hotline right away.

🩸

Metabolic problems

Low blood sugar, liver disease, kidney disease, and electrolyte abnormalities can all cause seizures. Blood and urine testing are often the first steps to look for these problems.

💥

Head trauma

A recent fall, collision, or other head injury can lead to seizures and is an emergency. Cats may seem quiet or hide after trauma, so even subtle signs deserve attention.

What to Do at Home

If your cat is having a seizure, focus on safety and getting veterinary help. Most seizures are short, but repeated or prolonged seizures can become life-threatening. Do not put your hands near your cat’s mouth, and do not try to restrain them. Because cats can have subtle focal seizures and often hide illness, even a brief episode should be taken seriously.

Stay calm and time the seizure if you can.
Move nearby objects, stairs, other pets, and hazards away so your cat is less likely to be injured.
Keep your hands away from your cat’s mouth; cats do not swallow their tongues during seizures.
Dim lights, reduce noise, and keep the area quiet while your cat recovers.
Once the seizure stops, note how long it lasted and record what happened before, during, and after the episode.
Take a video only if you can do so safely, then call your veterinarian right away or go to an emergency clinic if the seizure is prolonged, repeated, or your cat is not recovering.

Frequently Asked Questions About Cat Seizures

What does a seizure look like in a cat?

A cat seizure can look dramatic, with falling over, stiffening, paddling, drooling, urinating, or loss of consciousness. But feline seizures can also be subtle, such as facial twitching, staring, chewing motions, a twitching limb, sudden collapse, or unusual behavior before or after the episode.

Is one seizure in a cat an emergency?

Yes, a first-time seizure should be treated as an emergency or at least a same-day urgent veterinary problem. While a single short seizure may stop on its own, cats often have an underlying illness, toxin exposure, metabolic problem, trauma, or brain disease that needs prompt evaluation.

What should I do while my cat is having a seizure?

Keep your cat safe, move hazards away, dim the lights, and time the event. Do not hold your cat down, and do not put your fingers or any object in their mouth. Once the seizure stops, call your veterinarian immediately for next steps.

What causes seizures in cats?

Common causes include brain disease, tumors, infections, toxin exposure, head trauma, and metabolic problems such as low blood sugar or liver or kidney disease. Sometimes no clear cause is found and the condition is called idiopathic epilepsy, but this is diagnosed less often in cats than in dogs.

How do vets diagnose and treat seizures in cats?

Veterinarians usually start with a history, physical exam, neurologic exam, bloodwork, and urine testing to look for metabolic disease, toxins, or organ problems. Some cats also need blood pressure testing, imaging such as MRI or CT, or cerebrospinal fluid testing. Treatment depends on the cause and may include antiseizure medication and treatment of the underlying disease.
