Seizures in Rabbits: Causes and What to Do

In this guide

Watching a rabbit have a seizure is frightening, and it always warrants an emergency vet visit. Seizures are a symptom rather than a disease in themselves, and finding the underlying cause is the key to treating them.

What a seizure looks like

Signs range from mild, such as brief twitching, disorientation or a glassy stare, to severe episodes involving full-body convulsions, paddling limbs, loss of balance, or temporary loss of consciousness. A rabbit may also roll or circle repeatedly before or after an episode.

Common causes

• Encephalitozoon cuniculi, a parasite that affects the brain and nervous system and is a leading cause of seizures in pet rabbits.
• Head trauma from a fall or a collision.
• Heatstroke, which is a particular risk in Indian summers.
• Severe toxin exposure, including some houseplants and pesticides.
• Underlying organ disease, such as advanced kidney or liver problems.
• Less commonly, brain tumours or strokes, particularly in older rabbits.

What to do during a seizure

Do not try to restrain your rabbit or put anything in its mouth. Clear the immediate area of anything it could injure itself on, dim bright lights and reduce noise, and time the episode if you can. Once it has passed, keep the rabbit warm, quiet and in a safe enclosed space, and get to a vet immediately, even if the rabbit seems to recover quickly.

Diagnosis and treatment

A vet will typically run blood tests, check for E. cuniculi exposure, and may recommend imaging if a structural cause like a tumour is suspected. Treatment depends entirely on the cause: E. cuniculi is managed with an antiparasitic course, usually fenbendazole, taken daily for around a month, while recurring seizures from other causes may need long-term anti-seizure medication and regular monitoring.

Life after a single seizure

One isolated seizure with a clear, treatable trigger, such as heatstroke, does not automatically mean a rabbit will have another. Many rabbits go on to live full, normal lives after appropriate treatment and monitoring. Recurring or worsening seizures point to a chronic underlying cause and generally need ongoing veterinary management rather than a single course of treatment.

Reducing the risk of E. cuniculi at home

Since E. cuniculi spreads through urine, particularly in multi-rabbit households, keeping enclosures clean, disinfecting shared spaces regularly, and quarantining any newly adopted rabbit before introducing it to an existing one all reduce transmission risk. This is especially relevant in India given how many pet rabbits come from crowded pet shop or breeder conditions where the parasite can circulate undetected.
