Managing Cats With Epilepsy and Seizures

In this guide

Watching a cat have a seizure is frightening, but understanding what is happening and how to respond calmly makes a real difference, both for your cat's safety and your own peace of mind.

What a seizure looks like

Seizures result from a burst of abnormal electrical activity in the brain and can look quite different from cat to cat. Some are dramatic, with the whole body convulsing and loss of consciousness. Others are subtler, involving a specific part of the body twitching, sudden disorientation, or brief unusual behaviour that is easy to miss or misread.

True epilepsy is uncommon in cats

Unlike in dogs, primary or idiopathic epilepsy, meaning seizures with no identifiable structural cause, is relatively rare in cats. Most feline seizures are secondary to an underlying issue, such as a brain tumour, a past head injury, an infection or inflammation of the brain, liver disease, low blood sugar, high blood pressure, or toxin exposure. Because of this, vets generally investigate thoroughly for an underlying cause before settling on a diagnosis of epilepsy.

What to do during a seizure

• Stay calm and move nearby objects out of the way so your cat does not injure itself
• Do not put your hands near your cat's mouth, since cats have no risk of swallowing their tongue and you may be bitten unintentionally
• Time the seizure if you can, since duration matters for treatment decisions
• Keep the room quiet and dim, and avoid handling your cat until it has fully come round

When it is an emergency

A seizure lasting more than two to three minutes, multiple seizures in quick succession without full recovery between them, or a first ever seizure in a cat, all warrant an urgent vet visit. A seizure that will not stop, known as status epilepticus, is a life threatening emergency requiring immediate treatment.

Diagnosis and treatment

Your vet will typically run blood work to rule out metabolic causes, and may recommend advanced imaging such as an MRI if a structural brain problem is suspected. If a specific cause is found, treatment focuses there. When no cause is identified and seizures recur, long term anti-seizure medication, most often taken for the rest of the cat's life, helps reduce how often and how severely seizures occur. Full seizure freedom is not always achievable, but a meaningful reduction in frequency and severity is a realistic and worthwhile goal for most cats.

Keeping a seizure diary

Once your cat has had more than one seizure, keeping a simple log of the date, time, duration and what the seizure looked like helps your vet judge whether treatment is working over time. Filming an episode on your phone, if you can do so safely without trying to touch or restrain your cat, is genuinely one of the most useful things you can bring to a vet appointment, since seizures rarely happen on cue during a clinic visit.
