Seizures

Overview

Seizures in cats involve a sudden, uncontrolled burst of abnormal electrical activity in the brain, typically causing involuntary muscle movements (which can range from mild twitching or staring/disorientation to full-body convulsions), and are sometimes preceded by unusual behavior (restlessness, hiding, vocalizing) and followed by a post-seizure period of confusion, temporary blindness, or unusual behavior lasting minutes to hours. Causes range from epilepsy and toxin exposure to underlying conditions like liver disease, brain tumors, or severe low blood sugar — a first-time seizure specifically always warrants a full veterinary workup to identify the cause rather than being assumed to be "just" epilepsy.

First Aid Steps

1. Stay calm and do not attempt to hold, restrain, or put anything in the cat's mouth during a seizure — cats cannot swallow their tongue (a persistent myth), and attempting to intervene physically risks injury to both you and the cat
2. Clear the immediate area of anything the cat could injure themselves on — move furniture, remove nearby objects, but do not try to move the cat itself unless they are somewhere genuinely dangerous like near stairs or a pool
3. Time the seizure from start to finish — this information is genuinely useful for the veterinarian and helps you recognize if a seizure is lasting dangerously long
4. Dim lights and reduce noise/stimulation in the area if possible, since sensory input can sometimes prolong or worsen a seizure
5. Once the seizure ends, keep the cat calm and confined in a safe space during the confused post-seizure period, which can last anywhere from minutes to a few hours
6. Contact a veterinarian promptly, especially for a first-ever seizure, a seizure lasting more than 2-3 minutes, or multiple seizures occurring in succession without full recovery between them (cluster seizures)

When to Seek Emergency Care

A seizure lasting more than 5 minutes (status epilepticus) is a genuine emergency requiring immediate veterinary care, as is any cluster of multiple seizures without recovery in between. Any first-time seizure warrants a veterinary visit to investigate the underlying cause, even if the cat seems to recover normally afterward, and any seizure in a cat with known toxin exposure should be treated as a poisoning emergency alongside the seizure itself.

Prevention

Prevention depends heavily on the underlying cause — for epilepsy, consistent medication compliance if prescribed is the main preventive measure; for toxin-triggered seizures, standard poison-prevention practices apply; for cats with a diagnosed seizure disorder, working with a veterinarian to identify and avoid any specific triggers noted in that individual cat's pattern can help reduce frequency.
