If your cat is seizing right now, stay calm and keep your hands away from your cat’s mouth. Move any hard or sharp objects out of reach, and let the seizure run its course without trying to hold your cat down. Most seizures end on their own within one to two minutes. If the seizure lasts longer than five minutes, that is a life-threatening emergency and your cat needs veterinary care immediately.
What to Do During the Seizure
Your instinct will be to comfort your cat, but restraining a seizing cat can injure both of you. During a seizure, your cat doesn’t recognize you and may bite hard enough to cause serious harm. The American Red Cross advises keeping your hands away from the mouth entirely.
Here’s what actually helps:
- Clear the space. Push furniture, heavy objects, or anything with sharp edges away from your cat. If your cat is on an elevated surface like a bed or counter, gently slide them to the floor only if you can do so without restraining them.
- Reduce stimulation. Turn off the TV, dim the lights, and keep other pets and children out of the room. Noise and bright light can intensify or prolong the episode.
- Note the time. Glance at a clock when the seizure starts. Knowing the exact duration is one of the most useful things you can tell your vet.
- Record video if possible. Seizures in cats often look different from what people expect. Many cats vocalize loudly, drool heavily, or show aggression rather than the full-body convulsions you might picture. A video gives your vet far more information than a verbal description.
The Five-Minute Rule
A seizure that continues for longer than five minutes is classified as status epilepticus, a condition where the brain cannot stop the electrical storm on its own. It can cause dangerous overheating, brain swelling, and organ damage. If your cat seizes continuously past the five-minute mark, or has multiple seizures in a row without fully waking up between them, get to an emergency vet without delay. Wrap your cat loosely in a towel for safe transport, but do not pin them down.
A single seizure that stops within a couple of minutes is frightening but not usually an immediate emergency. You should still contact your vet within the next 24 hours to start figuring out the cause.
What Happens After the Seizure Stops
Once the seizure ends, your cat enters a recovery phase that can look almost as alarming as the seizure itself. Cats commonly appear disoriented, pace aimlessly, bump into walls, seem temporarily blind, or act unusually clingy or aggressive. Some hide for hours. Others vocalize or drool excessively. This recovery period can last anywhere from a few minutes to several days, though most cats return to normal behavior within a few hours.
During this time, keep the environment quiet and dim. Offer water but don’t force food. Your cat may not recognize familiar surroundings right away, so block off stairs and keep them in a single room where they can’t hurt themselves stumbling around. Don’t pick them up unless necessary, as they may lash out while still confused.
What to Record for Your Vet
The details you capture in the minutes around a seizure are genuinely valuable for diagnosis. Write down what your cat was doing right before the seizure started, since some cats show warning signs like staring blankly, twitching their whiskers, or suddenly freezing. Note exactly what the seizure looked like: did the whole body convulse, or was it limited to the face or one side? Did your cat lose consciousness or stay partially aware? Was there drooling, urination, or vocalization?
Also record how long the seizure lasted, how your cat behaved afterward, and how long it took for them to seem normal again. If your cat has more than one episode, track the dates and times. Patterns in frequency and timing help your vet narrow down what’s going on.
Why Cats Have Seizures
Seizures in cats work differently than in dogs. In dogs, inherited epilepsy with no identifiable cause is common. In cats, the rate of this type of epilepsy is much lower. Secondary causes, meaning something structurally or chemically wrong, are more frequently behind feline seizures. That’s why vets take a first seizure in a cat seriously and typically want to run diagnostics.
The causes fall into a few broad categories. Problems outside the brain, like low blood sugar, liver disease, exposure to toxins (certain plants, flea treatments meant for dogs, or household chemicals), and severe infections can all trigger seizures by disrupting the brain’s chemical environment. These are sometimes called reactive seizures because the brain itself is healthy but reacting to a body-wide problem. Problems inside the brain, such as tumors, inflammation, infections that reach the nervous system, or head trauma, cause seizures by directly damaging brain tissue.
That said, roughly half of cats with seizures end up classified as having epilepsy of unknown cause after extensive testing. So a diagnosis of “we can’t find a structural reason” is also common and doesn’t mean something was missed.
Sound-Triggered Seizures in Older Cats
One pattern worth knowing about: some older cats develop seizures triggered by specific high-pitched sounds. This condition, identified in cats typically in their second decade of life, is set off by things like crinkling tin foil, tapping on glass, clicking a computer keyboard, or jangling keys. The sounds responsible tend to be high-pitched and relatively quiet. Louder or more persistent versions of the same sound can trigger more severe seizures.
If your senior cat’s seizures seem to coincide with specific noises, mention this to your vet. Identifying and minimizing exposure to the triggering sounds can meaningfully reduce seizure frequency.
What the Vet Will Look For
After a first seizure, your vet will likely start with blood work to check for metabolic causes: blood sugar levels, liver and kidney function, and signs of infection or toxin exposure. These tests can quickly rule in or rule out problems outside the brain. If blood work comes back normal, advanced imaging like an MRI may be recommended to look for structural changes inside the brain.
Your vet will also perform a neurological exam, though they’ll account for the fact that a cat examined shortly after a seizure will often show abnormalities that are part of the recovery phase rather than signs of permanent damage. The timing of the exam matters.
Long-Term Management
Not every cat that has a single seizure needs daily medication. If seizures are infrequent and brief, your vet may recommend monitoring and keeping a seizure log rather than starting treatment right away. Medication typically becomes the recommendation when seizures happen more than once every four to six weeks, when they cluster in groups, or when they’re severe.
The most commonly prescribed anticonvulsant for cats is phenobarbital, usually given twice daily. Cats on this medication need periodic blood tests to make sure the drug stays within a safe and effective range. Side effects in the early weeks can include increased appetite, mild sedation, and wobbliness, though most cats adjust. A newer option that some vets prefer works through a different mechanism and may have fewer side effects, though it requires more frequent dosing.
Consistency matters more than anything with seizure medication. Missed doses are a recognized cause of breakthrough seizures. If your cat is prescribed daily medication, building it into a fixed routine and using a pill tracker can prevent gaps that lead to setbacks.
