What to Do If Your Cat Has a Seizure: Medication and Emergency Response

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Immediate safety measures during a seizure include moving hazardous objects away from the cat and avoiding direct contact with the mouth, as cats do not swallow their tongues and restraint can cause injury.
• Emergency veterinary care is critical if a seizure lasts longer than five minutes, if two or more seizures occur within 24 hours, or if the cat exhibits respiratory distress or fails to regain consciousness between events, as these can indicate status epilepticus or severe underlying pathology.
• Differentiating seizures from other neurological or systemic events like syncope or vestibular disease is crucial, and video recordings are invaluable diagnostic aids for veterinarians to assess the specific clinical presentation.
• Toxins, head trauma, infections (e.g., toxoplasmosis), and metabolic derangements (e.g., liver disease, hypoglycemia) are common underlying causes of seizures in cats, necessitating thorough diagnostic workups including blood chemistry panels and potentially advanced imaging.
• Administering any medication without explicit veterinary prescription is strongly contraindicated; human anti-seizure drugs or incorrect dosages can be fatal due to species-specific metabolism and drug sensitivities.
• Long-term management of epilepsy, if diagnosed, involves consistent daily administration of prescribed anticonvulsant medications (e.g., phenobarbital, levetiracetam) with regular veterinary monitoring of drug levels and organ function to ensure efficacy and safety.

If your cat is having a seizure right now, your first job is to keep them safe and time the event. Do not put your hands near their mouth. Do not try to hold them still. Move furniture and hard objects out of the way, dim the lights, and speak softly. Most seizures stop on their own within one to three minutes. If the seizure lasts longer than five minutes, or if your cat has two or more seizures within 24 hours, this is an emergency and you need to go to a veterinary emergency room immediately.

After the seizure stops, your cat may be confused, restless, drooling, or temporarily blind. This is called the post-ictal phase, and it can last minutes to hours. Keep them in a quiet, confined space and call your regular veterinarian for guidance. Do not give any medication at home unless a veterinarian has specifically prescribed it for this cat and this situation. Seizures have many causes, and the wrong drug or the wrong dose can make things worse.

What a Seizure Actually Looks Like

A generalized seizure, sometimes called a grand mal seizure, is the dramatic event most owners picture. Your cat falls onto their side, stiffens, and then paddles their legs. They may drool, urinate, defecate, or vocalize. Their eyes may roll back or stare blankly. This phase usually lasts under two minutes.

Some seizures are subtler. A focal seizure may only affect one part of the body, such as one leg twitching, one side of the face twitching, or repetitive blinking. Your cat may seem to stare at nothing, chase their tail, or bite at the air. These can be easy to miss or mistake for odd behavior. If you see any of these signs, record them on your phone. Video is extremely helpful for your veterinarian.

What Is Most Likely Going On

In cats, the most common cause of seizures is not epilepsy. Epilepsy is a brain disorder that causes repeated, unprovoked seizures, and it is diagnosed more often in dogs than in cats. When a cat has a seizure, the first suspicion is usually an underlying medical problem outside the brain.

Toxins are a leading cause. Common culprits include lilies, permethrin (found in some dog flea products), certain essential oils, and human medications such as ibuprofen or acetaminophen. If you think your cat may have eaten something toxic, do not wait for another seizure. Call a poison control line and go to an emergency vet immediately.

Other possible causes include head trauma, brain tumors, infections such as toxoplasmosis, liver disease, kidney failure, and low blood sugar. Your veterinarian will need a full history and likely blood work to narrow these down. The MSD Veterinary Manual Pet Owner Version explains that identifying the underlying cause is essential because treatment differs completely depending on what is wrong.

What Else It Could Be

Not every collapse or twitch is a seizure. Fainting, also called syncope, can look similar but is caused by a sudden drop in blood flow to the brain. A cat that faints usually goes limp instead of stiff, and recovers quickly once lying down. Heart problems are a common cause of fainting in cats.

Vestibular disease, which affects the balance system in the inner ear, can cause head tilt, circling, and falling over. This can look alarming but is not a seizure. Pain, severe weakness, or a reaction to a medication can also mimic seizure activity. A video recording of the event is the single most useful thing you can bring to your veterinarian, because the pattern of movement helps them tell these conditions apart.

Why You Should Not Give Medication Without a Vet

Seizure medications for cats are prescription drugs that require careful dosing based on your cat's weight, health status, and the underlying cause. Giving a human anti-seizure drug can be fatal. Giving a leftover pet medication from another animal can also be dangerous, because the dose may be wrong or the drug may be inappropriate for cats.

The FDA Safe Use of Pet Medications guidance stresses that medication errors are common and preventable. Always confirm the drug name, strength, and dose with your veterinarian before giving anything. If your cat is prescribed a seizure medication, you will need to give it on a strict schedule. Missing a dose can trigger a seizure, and doubling a dose can cause sedation, wobbliness, or worse.

What Your Veterinarian Will Do

Your veterinarian will take a detailed history and perform a physical and neurological exam. They will likely recommend blood tests to check organ function, blood sugar, and electrolyte levels. Depending on the findings, they may suggest imaging such as an MRI or a spinal fluid sample. These tests help rule out structural problems in the brain.

If no underlying cause is found and your cat has repeated seizures, your veterinarian may diagnose epilepsy and start a daily medication. The goal is to reduce the frequency and severity of seizures, not necessarily to stop them completely. Dosing must come from the treating veterinarian, and it may be adjusted over time based on your cat's response and blood levels. The American Veterinary Medical Association advises owners to work closely with their veterinarian to manage chronic conditions and to report any changes promptly.

What You Can Do Right Now, Safely

Your main job during a seizure is to keep your cat from hurting itself and to keep yourself safe. A seizing cat is not aware of its surroundings and may bite or scratch without meaning to. Do not put your hands near its mouth. Cats do not swallow their tongues, so there is no need to reach inside.

Move nearby furniture, sharp objects, or anything that could fall on the cat. If the cat is on a high surface like a sofa or bed, gently slide it to the floor onto a blanket or towel. Do not hold the cat down and do not try to restrain its limbs. Holding a seizing cat does not stop the seizure and can injure you or the cat.

Dim the lights and reduce noise if you can. Speak in a low, calm voice. Time the seizure from the moment it starts to the moment the movements stop. Most seizures last one to three minutes. If the movements continue past five minutes, or if one seizure follows another without the cat waking up in between, this is a life-threatening emergency called status epilepticus. You must get to an emergency veterinarian immediately.

After the movements stop, your cat may be confused, restless, blind, or unusually hungry or thirsty. This is called the post-ictal phase and can last minutes to hours. Keep the cat in a quiet, confined space with soft bedding. Do not offer food or water until the cat is fully alert and standing normally. A cat that is still disoriented can choke or inhale water.

What You Must Never Do

Do not give any medication during a seizure. A seizing cat cannot swallow safely, and medication given by mouth can go into the lungs. Do not give diazepam, also called Valium, or any other human anti-seizure drug unless a veterinarian has prescribed it for this exact cat and this exact situation. The dose for a cat is very different from a human dose, and the wrong amount can stop the heart or breathing.

Do not put anything in the cat's mouth, including your fingers, a spoon, or a towel. Do not pour water on the cat. Do not try to cool it down. Do not assume the seizure will pass without help. If the seizure is longer than five minutes, or if the cat has more than two seizures in 24 hours, this is an emergency even if each one is short.

What to Write Down Before You Call

A veterinarian will need specific facts, not guesses. Write these down as soon as the seizure ends:

• The date and exact start time of the seizure
• How long it lasted, in minutes and seconds
• What the cat was doing just before it started, for example sleeping, eating, or playing
• What the body did during the seizure, such as paddling legs, stiffening, drooling, or losing urine or stool
• Whether the cat lost consciousness or seemed aware
• How the cat behaved afterward, and for how long
• Any known exposure to toxins, such as flea products for dogs, lilies, chocolate, or rat poison
• Any recent head injury, even a small fall
• Any medications or supplements the cat takes regularly

If you can, record a video of the seizure. This is extremely helpful for your veterinarian because the movements can look different depending on the cause. Do not delay emergency care to take a video. Only record if the cat is safe and you have time.

The Emergency Action Plan

Write this plan down and keep it near your phone or on the refrigerator. Fill in your veterinarian's number and the nearest 24 hour emergency clinic before you need them.

Step 1: Stay calm and start timing. Note the time the seizure starts.

Step 2: Clear the area. Move furniture and objects away. Slide the cat to the floor if it is on a high surface.

Step 3: Do not touch the mouth. Do not restrain the cat. Do not give any medication.

Step 4: Call your veterinarian immediately after the seizure stops. If the seizure lasts more than five minutes, or if another one starts before the cat wakes up, go to the emergency clinic now and call them on the way.

Step 5: Keep the cat quiet and confined in a dark, calm room until it is fully alert.

Step 6: Write down everything you observed, using the list above.

Signs That Require Immediate Veterinary Attention

Some situations cannot wait for a regular appointment. Go to an emergency clinic right away if any of these occur:

What the Veterinary Visit Usually Involves

Your veterinarian will ask about the seizure details you wrote down. They will also ask about your cat's age, diet, vaccination history, and any medications. A full physical and neurological exam comes first. The vet will check your cat's reflexes, pupils, balance, and response to touch.

Blood tests are common. These check liver and kidney function, blood sugar, calcium levels, and signs of infection. Urine tests may also be done. If the blood work is normal and your cat has had more than one seizure, your veterinarian may recommend advanced imaging like an MRI or a spinal fluid tap. These tests look for structural problems in the brain, such as tumors or inflammation.

The cost of this workup varies widely. A basic blood panel and exam might fall in the range of $150 to $400. Advanced imaging can run from $1,000 to $3,000 or more. These are general ranges only. Prices vary by region, clinic, and whether the hospital is a specialty center. Ask for a written estimate before any expensive test.

If your cat has repeated seizures, your veterinarian may prescribe an anti-seizure medication such as phenobarbital or levetiracetam. The dose is calculated precisely for your cat's weight, and it must come from your veterinarian. The US Food and Drug Administration warns that giving the wrong dose of any pet medication is a common cause of harm, so never adjust the dose on your own. Blood levels of these drugs are often checked regularly to keep the dose safe and effective.

Your veterinarian will also explain when to give rescue medication at home, if that is appropriate for your cat. This is only done after a diagnosis and with clear instructions. It is never a substitute for emergency care when the seizure is prolonged.

Common Mistakes Owners Make During and After a Seizure

When your cat is seizing, fear can override logic. Knowing the common errors helps you stay calm and act correctly.

Mistake: Putting your hand near the cat's mouth. A seizing cat is not aware of its surroundings. It may bite hard, even if it has never bitten before. Do not try to hold the tongue or remove anything from the mouth. Cats rarely swallow their tongue. Keep your hands away from the face.

Mistake: Restraining the cat firmly. Holding a seizing cat down does not stop the seizure and can injure you or the cat. Move nearby furniture away so the cat cannot hit hard objects. Let the seizure run its course on the floor.

Mistake: Waiting to see if it stops before calling anyone. A single seizure that lasts under two minutes is not always an emergency, but you cannot know the cause at home. Call your veterinarian immediately after the seizure ends. If the seizure lasts longer than two minutes, or if another one starts before the cat fully recovers, this is an emergency. Go to a veterinary hospital now.

Mistake: Giving human medication. Never give your cat human seizure drugs, pain relievers, or sedatives. Cats process medications differently than people or dogs. A dose that seems small can be toxic. The FDA warns that giving pet medication incorrectly is a leading cause of drug errors. Dosing must come from your veterinarian, who will weigh your cat and choose a drug and dose based on the specific condition.

Mistake: Assuming the first seizure is epilepsy. Many conditions cause seizures, including toxins, liver disease, low blood sugar, head trauma, and infections. Epilepsy is a diagnosis of exclusion, meaning your vet rules out other causes first. Do not assume your cat has epilepsy until a veterinarian has examined it and run tests.

How to Reduce the Chance of Another Seizure

You cannot always prevent seizures, but you can lower the risk of known triggers.

Give medication exactly as prescribed. If your vet prescribes an anti-seizure drug, give it at the same time every day. Missing a dose is a common reason seizures return. The FDA's guidance on safe pet medication use explains why consistency and correct measuring matter. Never double a dose if you miss one. Ask your vet what to do.

Keep your cat indoors. Outdoor cats face toxins, traffic, and head trauma, all of which can cause seizures. An indoor cat is easier to monitor for changes in behavior or medication side effects.

Maintain a steady routine. Stress can trigger seizures in some cats. Keep feeding times, litter box placement, and sleeping areas consistent. If you must change the home environment, do it gradually.

Track seizures on a calendar. Note the date, time, duration, and what the cat was doing before the seizure. This record helps your veterinarian adjust treatment. The American Veterinary Medical Association's pet owner resources recommend keeping a health log for chronic conditions.

What Recovery and Ongoing Management Usually Look Like

Recovery depends on the cause. For a single seizure with no underlying disease, the cat may return to normal within hours. For cats with epilepsy, management is lifelong.

After a seizure, most cats go through a post-ictal phase. They may seem confused, restless, blind, or hungry. This phase can last minutes to hours. Keep the cat in a quiet, dim room with soft bedding. Offer water but do not force it. Do not feed until the cat is fully alert and walking normally.

If your cat is started on anti-seizure medication, expect a settling-in period. It can take one to three weeks to reach a steady level in the blood. Your vet will likely schedule a follow-up blood test to check drug levels and liver function. The MSD Veterinary Manual for pet owners notes that regular monitoring is part of long-term seizure care.

Some cats have breakthrough seizures even on medication. This does not mean the drug failed. Your vet may adjust the dose or add a second drug. Never change the dose on your own.

The cost of managing seizures varies widely. Initial testing, such as blood work and imaging, can range from a few hundred to over a thousand dollars depending on your region and clinic. Ongoing medication is usually modest. Talk to your vet about a plan that fits your budget.

Frequently Asked Questions

Can a cat die from a seizure? A single short seizure rarely causes death. The danger comes from seizures that last too long, cluster without recovery, or stem from a serious underlying cause like poisoning or brain disease. Prolonged seizures can cause overheating, brain damage, or breathing problems. If a seizure lasts more than two minutes, or if your cat has several in one day, treat it as an emergency and go to a veterinary hospital immediately.

Should I let my cat sleep after a seizure? Yes. Sleep is normal and helpful after a seizure. The post-ictal phase is exhausting. Place your cat in a quiet, safe room with soft bedding and fresh water nearby. Check on it every 15 to 30 minutes. If your cat does not wake up within a few hours, or if it seems unable to stand or breathe normally, contact your veterinarian.

How do I know if my cat needs daily medication? Your veterinarian decides based on seizure frequency, severity, and cause. Cats with one seizure from a treatable cause may not need daily drugs. Cats with epilepsy usually start medication after a second seizure, or after a single severe seizure. Your vet will explain the risks and benefits. Do not request or refuse medication without discussing it with your vet.

Can stress cause a seizure in my cat? Stress can trigger seizures in cats already prone to them, but stress alone does not cause epilepsy. Common stressors include moving, new pets, loud noises, or changes in routine. If your cat has seizures only around stressful events, your vet may recommend environmental changes or medication. Keep a diary of events around each seizure to share with your vet.

What should I do if my cat seizes in the middle of the night? Stay calm and follow the same safety steps. Time the seizure. If it stops within two minutes, let the cat recover in place and call your vet in the morning. If it lasts longer, if a second seizure follows, or if the cat does not regain normal behavior within 30 minutes, go to an emergency veterinary hospital. Do not wait until morning for these signs.

Will my cat have a normal life with epilepsy? Most cats with epilepsy live good lives with proper medication and monitoring. Seizures may be controlled for months or years at a time. You will need to commit to daily medication, regular vet visits, and careful observation. Many owners find that tracking seizures and working closely with their vet gives their cat a stable, comfortable life.
