Coccidiosis in rabbits

Rabbit coccidiosis comes in intestinal and dangerous hepatic (liver) forms. Learn the signs, treatment with toltrazuril or diclazuril, dosing, and prevention.

Rabbits face two forms: intestinal coccidiosis (several Eimeria species) and hepatic (liver) coccidiosis caused by Eimeria stiedae, which can be far more serious.

Who is at risk

Weanling and young rabbits in hutches or colonies are most affected, especially where bedding stays damp and feces accumulate.

Symptoms of coccidiosis in rabbits

  • Diarrhea & poor growth. Intestinal disease causes soft stool, weight loss, and a pot-bellied look in kits.
  • Reduced appetite and weakness. Affected rabbits slow down and may stop eating.
  • Liver-form signs. Hepatic coccidiosis can cause jaundice, a swollen abdomen, and sudden decline.
  • Sudden death. Heavy infections in young kits can be fatal before other signs appear.

When to act

Blood in the stool, ongoing diarrhea, dehydration, or a young rabbit going downhill all warrant prompt veterinary attention. Confirm the diagnosis with a fecal test rather than guessing.

Treatment

Effective options for rabbits include:

  • Toltrazuril. A widely used triazine treatment for rabbit coccidiosis.
  • Diclazuril. Another effective coccidiostat, often used in feed or water for groups.
  • Sulfa drugs. Sulfaquinoxaline and related sulfonamides are also used, sometimes for the liver form.

Pair any treatment with supportive care — fluids, nutrition, and a clean, dry environment. The dosage reference shows typical published figures; a veterinarian must confirm what's right for your animal.

Coccidiosis should be confirmed with a fecal test, and several anti-coccidial drugs require a veterinarian's prescription. Vetr connects you with licensed veterinarians who can diagnose, advise, and prescribe when appropriate.

Prevention

  • Keep hutches dry; use raised wire flooring or clean bedding frequently so droppings don't build up.
  • Never let feed or water become contaminated with feces.
  • Quarantine new rabbits and treat before mixing with the colony.
  • The hepatic form warrants prompt veterinary care — do not wait it out.

Is it a risk to me or other animals?

Rabbit coccidia do not infect humans, but the liver form is dangerous to rabbits and needs veterinary attention quickly.

Frequently asked questions

What is the difference between the intestinal and liver forms?
Intestinal coccidiosis affects the gut and causes diarrhea and poor growth. Hepatic coccidiosis (E. stiedae) attacks the liver's bile ducts and is often more severe, sometimes causing jaundice or sudden death — it needs urgent veterinary care.
How do I stop coccidiosis in my rabbitry?
Dryness and cleanliness are everything. Keep droppings away from feed and water, clean hutches often, and quarantine new arrivals. Your vet may recommend a preventive coccidiostat during high-risk periods.
Is coccidiosis in rabbits contagious?
Yes, between rabbits — oocysts spread through contaminated feces, feed, and water. It is not transmissible to other species or people.
