Why Is My Rabbit Not Eating?

Published Last updated 5 min read

Quick answer

A rabbit that stops eating or passing droppings is a veterinary emergency in the UK. Unlike many dogs, rabbits can slide into life-threatening gut stasis within hours. Contact your vet today — do not wait until morning, and do not start syringe-feeding from a video. Information only, not a diagnosis.

Key takeaways

  • A rabbit that stops eating hay or passing droppings is a veterinary emergency in the UK — do not wait until morning.
  • Do not force-feed, give leftover gut medicines, or assume they are 'just moulting' if the tray is empty.
  • Dental pain, stress, low-hay diets and heat are common reasons; the vet still has to examine this rabbit.

Should you wait overnight if your rabbit has not eaten?

No. If hay is untouched and the litter tray has been empty for around 12 hours, phone a vet even if they still look “just quiet”. Rabbits hide pain; stillness is not reassurance. Skip this page and travel if they are hunched, grinding their teeth, or the belly feels tight.

This is the owner-question page. The condition it usually names is rabbit gut stasis (ileus). Use the out-of-hours directory if your usual clinic is closed, and confirm they see rabbits before you drive.

Why is appetite loss so dangerous in rabbits?

Rabbits depend on constant fibre movement. When chewing stops, motility slows, gas accumulates and pain makes them even less likely to eat. That cycle is why UK charities treat reduced droppings as a red flag the same day, not after a weekend of “monitoring”.

An empty tray for 12 hours matters even if they nibbled a herb at dawn. Count faecal pellets, not optimism.

What are the common reasons a UK rabbit stops eating?

None of these is a reason to wait:

  • Dental disease — spurs and overgrown crowns make hay painful. See overgrown teeth
  • Stress — fireworks, dogs at the run, travel, a new house, loss of a bonded partner
  • Diet — too many pellets or mix, not enough hay
  • Pain from surgery, flystrike, gas, or another illness
  • Heat without shade in a UK summer. Rabbit summer care
  • Gut stasis already underway — the not-eating is the emergency

We do not invent a percentage split of causes. Your vet still has to look in the mouth and feel the abdomen.

What should you do in the next hour?

  1. Phone the vet — describe species, when they last ate, when you last saw droppings, and any toxin, heat or surgery
  2. Offer hay and water — do not withhold “to see if they get hungry”
  3. Keep them warm and quiet — a carrier with familiar hay for the journey
  4. Do not syringe-feed unless that vet has just instructed you
  5. Do not give human painkillers, another pet's antibiotics, or leftover motility drugs from a previous rabbit

If you find maggots or a wet, soiled rear, say flystrike on the phone. That is its own emergency: flystrike.

Use the symptom checker only as language — then still call.

What will happen at the clinic?

Expect pain relief, fluids, motility treatment if appropriate, and a hunt for the cause — especially teeth. Some rabbits stay in for syringe feeding and monitoring. Ask for a written estimate when they are stable enough for that conversation; in a genuine emergency the team treats first. Typical UK fee bands sit on how much a vet costs — they are not tonight's invoice.

Register with a rabbit-savvy practice before you need one. Rabbit-friendly filter shows clinics that publish that they see rabbits; still confirm on the call. RCVS Find a Vet is the legal register.

How is this different from a dog off their food?

A bright dog that skips one meal can often wait for a same-day slot. A rabbit that skips hay cannot borrow that rule. Their gut is designed to keep moving fibre; once it slows, gas and pain make the next mouthful less likely. That is why this site’s dog appetite guide and this page give different clocks. If you keep both species, do not mix the waiting times.

If they are eating some pellets but no hay, that is not “at least they’re eating” — hay is the fibre that keeps motility going. Phone with that detail. The gut stasis page explains what the clinic is treating; this page is what you do before you arrive.

Who is this page NOT for?

Anyone already looking at a hunched rabbit and an empty tray — you need a phone, not another paragraph. Also skip “wait and see” if they are a baby, recently spayed or castrated, or you know they ate something they should not have. Prevention for next time — hay-first diet, vaccinations, dental checks — lives on the gut stasis and rabbit care guides. Tonight is the clinic.

Frequently Asked Questions

How long can a rabbit go without eating?
Do not plan around a number you found on a forum. UK welfare advice treats no hay and no droppings for around 12 hours as a reason to call a vet the same day. Gut stasis can follow quickly. Quiet, still rabbits are often painful, not 'settled'.
What is gut stasis in rabbits?
Gut stasis (ileus) is when the digestive system slows or stops. Gas builds, pain rises, appetite falls. It is one of the most common rabbit emergencies in the UK. The condition deep-dive is our gut stasis guide; this page is the owner question — what to do in the next hour.
Can dental problems stop rabbits eating?
Yes. Overgrown teeth and painful spurs are a leading reason rabbits stop chewing hay. Regular checks with a rabbit-savvy vet matter. Do not file teeth at home.
Should I force-feed my rabbit?
Not unless a veterinary surgeon has just examined them and told you how. Force-feeding a rabbit with a possible blockage can make things worse. Offer fresh hay, keep them warm and quiet, and travel to the clinic.
Who should not wait-and-see overnight?
Every owner whose rabbit has stopped hay and droppings. Especially babies, recently operated rabbits, those in a heatwave, and any rabbit with a hunched posture or tooth grinding. Phone, then drive.
