Rabbit Diarrhea: Causes, Cecotropes vs. True Diarrhea & What To Do
When a rabbit owner notices soft, wet, or messy droppings, the first question to ask is: is this true diarrhea or a cecotrope problem? The answer dramatically changes how urgent the situation is.
Understanding Rabbit Droppings
Rabbits produce two types of droppings:
Hard fecal pellets — the round, firm droppings you see in the litter box. These are waste material.
Cecotropes — soft, clustered, grape-like droppings produced by the cecum, rich in nutrients, protein, and beneficial bacteria. Healthy rabbits eat these directly from their anus, usually at night. You should almost never see cecotropes in the litter box — if you do, your rabbit isn't consuming them properly.
Cecotrope Problems vs. True Diarrhea
Soft/Mushy Cecotropes (Cecal Dysbiosis)
The most common "diarrhea" complaint in rabbits isn't true diarrhea at all — it's uneaten or abnormally soft cecotropes smeared around the rabbit's hindquarters and litter box. This happens when:
- The diet is too high in carbohydrates, sugar, or pellets and too low in hay
- The rabbit is overweight and can't reach their hindquarters to consume cecotropes
- There's an underlying GI imbalance
This is not a life-threatening emergency, but it does need dietary correction. Increase hay to unlimited amounts, remove all treats and fruit, and reduce pellets.
True Diarrhea
True diarrhea — watery, liquid stool in the absence of normal round pellets — is a medical emergency in rabbits. It can develop from:
- Bacterial infection (E. coli, Clostridium, Salmonella)
- Viral infection (Rabbit Hemorrhagic Disease, particularly in young rabbits)
- Parasites (Coccidia — especially in young or recently acquired rabbits)
- Inappropriate antibiotic use — some antibiotics are toxic to the rabbit GI microbiome
True diarrhea in rabbits causes rapid dehydration and can be fatal within 24-48 hours without treatment (AEMV Pet Care Guides, 2024).
How to Tell the Difference
| | Cecotrope Problem | True Diarrhea | |||| | Normal hard pellets present? | Yes | No | | Consistency | Soft, mushy, sticky | Liquid, watery | | Rabbit eating? | Usually yes | Often no | | Urgency | Non-emergency | Emergency |
Emergency Warning Signs
Go to an exotic vet immediately if:
- Your rabbit has watery liquid stool with no normal pellets
- Your rabbit is not eating or moving
- Your rabbit appears lethargic, cold, or limp
- The rabbit is very young (under 12 weeks)
- Onset was sudden and rapid

What To Do at Home (for cecotrope problems only)
- Remove all pellets, treats, and fresh vegetables temporarily and feed unlimited grass hay
- Ensure fresh water is available at all times
- Keep the hindquarters clean and dry to prevent flystrike (flies laying eggs in soiled fur)
- Monitor for normal pellet production — if pellets stop, seek care immediately
Still Not Sure if Your Rabbit Needs a Vet?
When you're not sure if this is wait-and-see or call-tonight, Voyage AI Vet triages in under 2 minutes. Describe what you're seeing in chat, share photos of your rabbit's droppings (or lack of) and their belly, or hop on a live video call if you want a second pair of eyes. Every answer comes with citations to the actual veterinary literature it's pulling from — so you see exactly where the guidance comes from, not just a chatbot's word.
