Why Is My Rabbit Not Eating? Gut Stasis Emergency (UK)
Published Last updated 2 min read
Quick answer
A rabbit that stops eating or passing droppings is a veterinary emergency in the UK. Unlike cats and dogs, rabbits can develop life-threatening gut stasis within hours. Contact your vet immediately — do not wait until the next day.
Why appetite loss is critical in rabbits
Rabbits depend on constant fibre movement through the gut. When eating stops, gut motility slows, gas accumulates and pain worsens — creating a dangerous cycle.
No droppings for 12 hours is a red flag even if your rabbit still looks quiet.
Common causes
- Dental disease — reduced hay chewing
- Stress — fireworks, predator noise, travel, new environments
- Incorrect diet — too many pellets, insufficient hay
- Pain from surgery, injury or underlying illness
- Heat stress in warm UK summers without shade
Warning signs
- Not eating hay or favourite greens
- Fewer or no droppings
- Hunched, painful posture
- Grinding teeth (pain sign)
- Bloated abdomen
- Lethargy or hiding
What your vet will do
Treatment may include pain relief, gut motility drugs, fluid therapy and syringe feeding. Underlying dental or disease causes must be addressed. Hospitalisation is often needed.
Prevention for UK owners
- 85% hay diet — unlimited good-quality hay daily
- Annual vaccinations against myxomatosis and RVHD
- Flystrike prevention in summer — check rear end twice daily
- Companion rabbit where possible (bonded, neutered pair)
- RWAF minimum space standards for housing and exercise

Frequently Asked Questions
- How long can a rabbit go without eating?
- Rabbits should not go more than 12 hours without eating hay or producing droppings. After this, gut stasis (ileus) becomes a serious risk requiring urgent veterinary care.
- What is gut stasis in rabbits?
- Gut stasis is when the digestive system slows or stops. Gas builds up, causing pain and further appetite loss. It is one of the most common rabbit emergencies in the UK.
- Can dental problems stop rabbits eating?
- Yes. Overgrown teeth and painful spurs are a leading cause of reduced hay intake. Regular vet dental checks are essential for UK pet rabbits.
- Should I force-feed my rabbit?
- Do not force food without veterinary guidance. Offer fresh hay and contact your vet immediately if your rabbit stops eating or passing droppings.
