My rabbit has diarrhea: what to do? Causes and emergencies
Diarrhea or soft droppings: a critical distinction
Finding abnormal droppings in a rabbit’s enclosure is legitimately worrying. But before reacting, identify exactly what you are looking at — the situation can range from a minor dietary imbalance to a life-threatening emergency.
Cecotropes: normal but frequently mistaken for diarrhea
Cecotropes are soft, dark-brown, grape-cluster-shaped droppings coated in a thin, slightly shiny mucous film. They have a strong smell. Rabbits produce them at night or early morning and eat them directly from their anus — a behavior called cecotrophy. You rarely see this happen. These droppings are nutritionally essential (proteins, vitamin B12, fatty acids, beneficial microorganisms).
Finding cecotropes on the floor means your rabbit is not consuming them — not that it is sick. Common reasons:
- Diet too rich in carbohydrates (too many pellets, fruits, or sugary vegetables)
- Overweight rabbit unable to reach its anus
- Joint pain in an older rabbit
- Excessive production caused by gut flora imbalance
Main solution: increase hay (aim for 80% of the daily ration), reduce pellets, temporarily remove fresh vegetables. If the problem persists beyond 3 to 5 days, consult a rabbit-savvy vet.
Soft droppings that are not cecotropes
Sticky, pasty, or mushy droppings without the grape-cluster shape or the mucous coating indicate a gut flora imbalance. Common causes: too-fast dietary change, excess fresh greens, insufficient hay. This is generally not an immediate emergency but requires prompt dietary correction.
To avoid these mistakes, check our guide on safe vegetables for rabbits and the list of foods rabbits cannot eat.
True diarrhea: recognizing the emergency
True diarrhea is characterized by entirely liquid or semi-liquid stools, strongly foul-smelling, sometimes yellowish or bloody. It is rare in healthy adult rabbits but serious as soon as it appears.
Main causes of diarrhea and abnormal droppings
Dietary imbalance (most common)
The rabbit’s intestinal microbiome is extremely sensitive to dietary changes. Common mistakes: too many fresh vegetables at once, introducing a new food without transition, excess fruit or treats. Insufficient hay is often the common denominator — long fibers structure transit and feed beneficial bacteria.

Bacterial and parasitic infections
Bacteria such as Clostridium perfringens or Escherichia coli can cause enterotoxemia — severe diarrhea with rapid deterioration of the animal’s general condition. Intestinal parasites (coccidia, Cryptosporidium) mainly affect kits. These causes require prompt veterinary care.
Inappropriate antibiotics
Certain antibiotics are strictly contraindicated in rabbits when given orally: penicillins, clindamycin, erythromycin, ampicillin, lincomycin. They destroy beneficial gut flora and allow pathogenic bacteria to proliferate, potentially causing fatal enterotoxemia. Never give any antibiotic to a rabbit without an explicit prescription from a rabbit-savvy exotic-pet vet.
Acute stress
Intense stress (moving, loud noise, arrival of a new animal) can speed up gut transit and produce softer stools for a few hours. This is generally not true diarrhea and resolves on its own.
Systemic illness or parasites
A urinary infection, abscess, coccidiosis, or other pathology can secondarily affect transit. If other symptoms accompany abnormal stools, do not wait — consult.
Signs of a life-threatening emergency
Contact a rabbit-savvy vet immediately if you see:
- Stools that are very liquid, bloody, or yellowish
- Rabbit that is lethargic, hard to rouse, or inactive
- Bloated and painful abdomen (animal refuses to be touched)
- Rabbit that refuses to drink for several hours
- A kit under 3 months with abnormal stools
- No droppings at all for more than 6 to 8 hours
Dehydration and endotoxemia can develop within hours in a rabbit. In a kit, a few hours are enough to become life-threatening. If your rabbit is also refusing to eat, read what to do if a rabbit stops eating.
What you can do before the vet visit
These steps limit deterioration but do not replace a consultation:
- Temporarily remove fresh vegetables, fruit, and pellets
- Offer unlimited hay only, plus fresh water
- Do not give human medications (human probiotics, loperamide, activated charcoal unless prescribed)
- Observe: quantity and appearance of droppings, water intake, general behavior
- Keep the rabbit warm (18–22 °C / 64–72 °F) without overheating
If the situation normalizes within 12 to 24 hours on hay alone, it was likely a minor dietary imbalance. When in doubt, consult.
Long-term prevention
- Unlimited hay at all times: the foundation of the diet and the best gut regulator
- Gradual dietary transitions over 10 to 14 days for any new food
- Fresh greens in moderation: 1 to 2 types per day, small amounts
- Fresh water renewed daily
- Rabbit-savvy vet for any antibiotic prescription — never use leftover human or cat/dog antibiotics
Proper daily feeding remains the best prevention. Check the full list of foods rabbits cannot eat to eliminate the most common risks.
Frequently asked questions
My rabbit has soft, grape-like droppings on the floor — is that diarrhea?
No, those are most likely cecotropes — soft, nutrient-rich droppings the rabbit normally eats directly from its anus. Finding them on the floor means your rabbit is not consuming them, usually because the diet is too rich in carbohydrates. Adjust the ration and see a vet if it persists beyond 3 days.
Is diarrhea dangerous for rabbits?
Yes. True diarrhea — very liquid, foul-smelling stools — is a veterinary emergency in adult rabbits. In kits under 3 months, it is an immediate life-threatening emergency: dehydration can be fatal within hours.
What should I give my rabbit if it has diarrhea?
Remove fresh vegetables, fruit, and pellets. Offer unlimited hay and fresh water only. Do not give human medications. See a rabbit-savvy vet promptly if stools are very liquid, the rabbit is lethargic, or you have a young animal.
Which foods can cause soft stools in rabbits?
Too many fresh vegetables at once, rapid dietary changes, excess fruit or sugary treats. Insufficient hay is often the root cause: long fiber keeps the gut flora balanced and the transit regular.
