My kitten seems completely fine now — do I still need a vet?

Yes. A kitten recovering quickly does not tell you what caused the seizure, and several possible causes, including some toxins and low blood sugar, need prompt treatment even once the seizure itself has stopped. Ring your vet and describe exactly what happened, even if your kitten now seems back to their normal self.

What does a seizure actually look like in a kitten?

It can range from brief stiffening, staring or twitching to a full collapse with paddling limbs, drooling and loss of consciousness. Afterwards a kitten is often disoriented, wobbly or unusually sleepy for a while, which is a normal part of recovering from a seizure rather than a separate problem needing its own treatment.

Can low blood sugar cause seizures in kittens?

Yes, particularly in very young or very small kittens, who have limited energy reserves and can develop dangerously low blood sugar quickly if they miss meals or are unwell. This is one of several reasons a kitten who has seized needs prompt veterinary attention rather than watching and waiting to see if they recover on their own.

How do I find an emergency vet out of hours?

Your own practice's answerphone will normally direct you to the out-of-hours service covering your area. Our directory of local vets also lists practices offering emergency and out-of-hours cover, which is worth bookmarking in advance rather than searching for it while you are already worried and short on time.

My kitten had a seizure — what to do

A kitten who has had a seizure needs a vet immediately, not in the morning. Ring your practice now, or an out-of-hours service if they are closed, and tell them what you saw. Everything below is for while you are getting there — it is not a substitute for that call.

Emergency — ring a vet now

This is a sign that needs a vet straight away, not later today. Ring your practice, or an out-of-hours service if they are closed, and describe what you are seeing.

Do this now

Ring the vet before anything else. If your own practice is closed, their answerphone will normally give you an out-of-hours number, and most areas have a dedicated emergency service. Tell them your kitten has had a seizure and roughly how long ago, and they will tell you whether to come straight in.

Keep the area around your kitten clear of anything they could knock into or fall from, such as furniture edges or a raised surface, but do not try to hold or restrain them during the seizure itself. Do not put your hands near their mouth — a kitten mid-seizure cannot control their jaw and there is no risk of them swallowing their tongue, so this is unnecessary and risks a bite.

Dim bright lights and keep the room quiet if you can, since noise and light can prolong a seizure in some animals. Time how long it lasts if you are able to, since this is genuinely useful information for your vet.

What to tell the vet

Say how long the seizure lasted, whether it has happened before, and what your kitten was doing immediately beforehand. Mention whether they lost consciousness, whether there was paddling or rigidity in the limbs, and how they seemed once it stopped — confused, sleepy, or back to normal quickly.

Tell them about anything your kitten could have got into, including houseplants, human medication, or any chemical or pesticide, since some poisonings cause seizures in cats. Mention their age, since very young or very small kittens are also more prone to low blood sugar, which can present this way.

If it is safe to do so and someone else can drive, a short phone video of the seizure is genuinely useful to a vet who will not see the episode themselves.

What a seizure can mean in a kitten

A seizure is a sign that something is disrupting normal brain activity, and the underlying cause in a kitten this age can range from a toxin, a congenital issue such as a liver shunt, low blood sugar, an infection, or in some cases idiopathic epilepsy. A single seizure does not tell you which of these it is.

Some causes are far more urgent than others, and several need treatment started quickly to give the best outcome, which is the whole reason this page says ring first and read later. A kitten who seems to recover fully within minutes still needs to be examined.

Afterwards

Expect your vet to want to examine your kitten and likely run some blood tests, since these help narrow down what caused the seizure, particularly in a young animal where several different causes are possible.

Write down what you saw as soon as you can while it is fresh in your memory, including the time and how long it lasted. If it happens again, that record, and any video you managed to take, will be genuinely useful to your vet.

If it happens more than once

A single seizure is always worth investigating, but a kitten who has more than one over a short period needs to be seen urgently rather than monitored at home, since repeated seizures, or one that does not stop within a few minutes, can themselves become dangerous and need emergency treatment to bring under control.

Keeping a simple diary of any further episodes — date, time, how long each lasted, and anything unusual beforehand — helps your vet build a clearer picture over time, which matters particularly if the cause is not obvious from the first examination and tests, and can change what treatment your vet decides to try next.
