What to do when your cat seizes
Watching your cat have a seizure is frightening. The most important thing is to stay calm and keep your cat safe. Here is a step-by-step guide:
- Do not restrain your cat. Hold back the urge to hug or hold them down. You could be injured, and restraint can prolong the seizure.
- Clear the area. Move furniture, sharp objects and anything hot away. Place a cushion or blanket under the head if possible.
- Dim lights and reduce noise. Turn off the TV, lower blinds and keep other pets away.
- Do not put anything in the mouth. Cats do not swallow their tongue during a seizure. Your fingers could be badly bitten.
- Time the seizure. Note the start and end time. This information is crucial for your vet.
- Stay until it ends. Most seizures last 1–3 minutes. Speak softly and wait.
After the seizure, your cat may be disoriented, wobbly or temporarily blind. This is called the post-ictal phase and can last minutes to hours. Keep them in a quiet, safe space and offer water once they are alert.
When to call the vet immediately:
- Seizure lasts longer than 3 minutes.
- Multiple seizures occur within 24 hours.
- Your cat does not regain consciousness.
- Seizure happens in water or near heat.
- Your cat is pregnant or has a known health condition.
Understanding seizures in cats
A seizure is a sudden surge of abnormal electrical activity in the brain. It can be generalised (whole body) or focal (one part of the body). Generalised seizures are more common and involve loss of consciousness, paddling limbs, drooling and sometimes loss of bladder control.
Focal seizures may show as twitching of the face, head turning, or unusual behaviour like fly-biting. Some cats have psychomotor seizures with bizarre behaviour such as tail chasing or sudden aggression.
Seizures are not always epilepsy. Epilepsy is a specific condition of recurrent seizures without an underlying cause. In cats, true epilepsy is less common than in dogs; underlying diseases are more often found.
Common causes of seizures in cats
Finding the cause is key to treatment. Your vet will consider:
- Toxins: Permethrin (found in some dog flea products), lilies, antifreeze, chocolate, caffeine, and certain human medications. In Malaysia, accidental poisoning from household products or plants is a real risk.
- Metabolic disorders: Low blood sugar (hypoglycaemia), low calcium, liver disease, kidney disease, and electrolyte imbalances.
- Brain disease: Tumours, infections (e.g., toxoplasmosis, feline infectious peritonitis), inflammation, or head trauma.
- Idiopathic epilepsy: Seizures with no identifiable cause, often starting between 1 and 5 years of age.
- Reactive seizures: Caused by a temporary problem like toxin exposure or low blood sugar; these resolve when the underlying issue is treated.
In Malaysia, infectious diseases such as toxoplasmosis and FIP are important considerations, especially in cats with access outdoors. Your vet may recommend blood tests and imaging.
How vets diagnose the cause
A thorough workup helps determine the best treatment. Expect your vet to:
- Take a detailed history: When did seizures start? How often? What was the cat doing? Any access to toxins?
- Perform a physical and neurological exam: Check reflexes, vision, and balance.
- Run blood tests: Complete blood count, biochemistry profile, and electrolyte panel to rule out metabolic causes.
- Test for infectious diseases: Depending on risk factors, tests for toxoplasmosis, FIV, FeLV, and FIP may be advised.
- Imaging: X-rays may rule out certain conditions, but MRI is the gold standard for brain imaging. Not all clinics have MRI; your vet may refer you to a specialist centre.
- Cerebrospinal fluid analysis: In some cases, to check for inflammation or infection.
Diagnosis is often a process of elimination. If all tests are normal and seizures are recurrent, idiopathic epilepsy may be diagnosed.
Treatment options for cat seizures
Treatment depends on the cause and frequency of seizures. The goals are to reduce seizure frequency and severity, minimise side effects, and improve quality of life.
Emergency treatment
For a seizure lasting over 3 minutes (status epilepticus), emergency vet care is needed. Vets may administer intravenous anti-seizure drugs such as diazepam or midazolam, and provide oxygen and supportive care.
Long-term medication
If seizures are frequent (e.g., more than one per month) or severe, your vet may prescribe daily anti-seizure medication. Common options include:
- Phenobarbital: A traditional first-line drug. It is effective but requires regular blood tests to monitor liver function and drug levels.
- Levetiracetam (Keppra): Often used as an add-on or sole therapy. It has fewer liver side effects but may be more expensive.
- Zonisamide: Another option, sometimes used when other drugs are ineffective.
- Gabapentin: Sometimes used for focal seizures or as an adjunct.
Medication is tailored to your cat. Never change or stop medication without veterinary guidance, as abrupt withdrawal can trigger severe seizures.
Managing underlying causes
If a metabolic disorder is found, treating it may stop seizures. For example, correcting low blood sugar or calcium. If a toxin is identified, decontamination and supportive care are needed. Brain tumours may be managed with medication, surgery, or radiation, depending on the case.
Complementary approaches
Some owners ask about dietary changes or supplements. There is limited evidence for these in cats. Always discuss with your vet before trying anything new. A calm, stress-reduced environment can help reduce seizure triggers.
Living with an epileptic cat
Caring for a cat with seizures requires patience and consistency.
- Medication routine: Give drugs at the same times daily. Use pill pockets or compounding if needed.
- Keep a seizure diary: Record date, time, duration, and what happened. This helps your vet adjust treatment.
- Safety-proof your home: Block stairs during seizure-prone periods, keep away from water features, and supervise outdoors.
- Avoid known triggers: Stress, flashing lights, and certain toxins.
- Regular vet visits: Every 3–6 months for blood tests if on medication.
Many cats with epilepsy live full, happy lives with proper management.
Comparison of common anti-seizure medications
| Medication | Common use | Key considerations |
|---|---|---|
| Phenobarbital | First-line for epilepsy | Requires regular blood tests; can affect liver; sedating initially |
| Levetiracetam | Add-on or sole therapy | Fewer liver effects; may need frequent dosing; cost varies |
| Zonisamide | Alternative or add-on | Monitor for side effects; limited availability in some clinics |
| Gabapentin | Focal seizures or adjunct | Sedation common; not a first-line sole drug for generalised seizures |
| Diazepam (emergency) | Emergency control | Given intravenously or rectally by vet; not for home use without guidance |
Note: This table is a general guide. Your vet will choose the best medication based on your cat's health, seizure type, and local availability. Prices vary; ask your Malaysian vet for an estimate.
When to see a vet
Seek veterinary care if your cat has a seizure, especially if:
- It is the first seizure.
- The seizure lasts more than 3 minutes.
- Seizures occur in clusters (more than one in 24 hours).
- Your cat is pregnant, very young, or elderly.
- There are signs of illness such as vomiting, diarrhoea, or lethargy between seizures.
- Your cat is on medication and seizures are not controlled.
Do not wait if you are unsure. It is better to have your cat checked.
Local context for Malaysian cat owners
In Malaysia, many cats live in apartments or landed homes with access to balconies or gardens. This can increase exposure to plants like lilies, which are highly toxic to cats. If you live in a high-rise, ensure balconies are cat-proofed and avoid toxic plants. In rainy seasons, some cats may be more prone to infectious diseases; keep up with vaccinations and parasite control. Always consult a local vet for advice tailored to your cat.
