My pet is having a seizure — what now?

Protect the pet from injury and start timing. The longer it lasts, the more it needs a vet now, not later.

First, how urgent is this?

Go now

  • A seizure lasting more than 5 minutes.
  • Several seizures in one episode, or another one shortly after.
  • Still unable to stand, not fully conscious, or breathing abnormally once it stops.
  • Cat: possible contact with lilies, rat bait or antifreeze.
  • Dog: any suspected poisoning or swallowed toxin.
  • A seizure after heat exposure, or a clearly high body temperature.

Contact your vet today

  • A first seizure that has fully passed, with normal behaviour afterwards.
  • Behaviour change around the seizure: circling, apparent blindness, a different personality.
  • Known epilepsy, but the seizures are coming closer together.
  • Drooling, losing bladder control or briefly not seeing after the seizure.

Record and observe

  • Known epilepsy already under vet care: record the time, length and pattern of each seizure, and bring the record to the next visit.

Before you set off

  • When it started and ended, and how long it lasted.
  • Film it. Keep your distance and never put your hand in the mouth.
  • Behaviour before and after: any warning signs, and how long until normal.
  • Move hard objects and furniture away, keep the room ventilated, and do not restrain the pet.
  • A list of medicines, the time of the last dose, and the dose record.
  • Do not give human medicine, and no food or water until fully conscious.

What your vet may ask and do

  • Ask: when the first seizure was, how many, and how long.
  • Ask: any behaviour change around them.
  • Ask: any chance of a toxin, head injury or poisoning.
  • Do: a neurological examination.
  • Do: blood tests (glucose, electrolytes, liver and kidney values, calcium).
  • Do: MRI or CT where needed.
  • Do: ongoing seizures need intravenous drugs to stop them, and admission for monitoring.
