My baby rabbit is not eating - what do I do right now?
Treat a baby or juvenile rabbit that has stopped eating as an emergency and call a rabbit-seeing vet now. Runny stool in an infant or juvenile rabbit is described by rabbit-health authors as life-threatening and needing immediate veterinary care. Doe rabbits nurse their kits only once, occasionally twice, in 24 hours, so a nest you never see feeding is usually normal; a kit that is cold, limp or has a wrinkled, sunken belly is not.

What to do in the next hour
- Call a vet who sees rabbits, or an emergency clinic, and say the rabbit is a baby and is off food. Young rabbits get worse faster than adults.
- Warm a cold kit slowly against a covered heat source before anything else. Do not feed a cold rabbit.
- Check for runny stool around the rear. Any diarrhoea in a baby or juvenile rabbit means go now.
- Weigh on a kitchen scale in grams and write the number down. Repeat at every feed so you can see the direction.
- Leave a nest of apparently unfed kits alone unless they are cold, limp or wrinkled: does feed only once or twice in 24 hours.
- Do not give cow's milk, and do not overfeed. Overfeeding is described as a leading cause of death in hand-reared kits.
Age, feeding and what off food means
Milestones from the Royal Veterinary College hand-rearing guide. Use them to judge whether what you are seeing is a normal nest or a rabbit in trouble.
| Age | Normal feeding | Off food means |
|---|---|---|
| Newborn to 3 weeks | Nursed by the doe once, sometimes twice, in 24 hours, in the nest | Same-hour vet call. Never seeing a feed is normal, a cold or limp kit is not |
| About 3 weeks | Leaves the nest fully furred and starts eating solids alongside milk | Same-hour vet call, and take a photo of the droppings with you |
| Weaning onwards | Unlimited grass hay plus the same food the rabbit was raised on | Same-hour vet call. Do not change the diet while a young rabbit is unwell |
| Any age with runny stool | Not applicable | Treated as life-threatening. Go immediately |
| Any age, cold or limp | Not applicable | Warm slowly, then go. Do not feed a cold rabbit |
When to see a vet today
See a vet today if you notice Any diarrhoea or runny stool in a baby or juvenile rabbit, Cold to the touch, limp, or not responding to handling, and A wrinkled, sunken belly and loose skin over the shoulders. These are the signs that should not wait for home care or a watch-and-see approach. If any of them appear, skip the rest of this guide and call your vet or an emergency clinic now - waiting is the risky option.
- ●Any diarrhoea or runny stool in a baby or juvenile rabbit
- ●Cold to the touch, limp, or not responding to handling
- ●A wrinkled, sunken belly and loose skin over the shoulders
- ●No droppings at all and no interest in food
- ●Crying or thrashing when the belly is touched
- ●Weight falling from one weigh-in to the next
Safe to monitor at home
Milder signs are usually safe to watch for a day or two: A nest of plump, warm, quiet kits you never see being fed, A newly weaned rabbit eating a little less on the first day in a new home, with normal droppings, and Fussiness about a new green while hay intake is unchanged. Keep notes and photos so you can spot a trend. Anything that worsens, spreads, or comes with appetite, energy or behavior changes moves out of this category and into a vet visit.

What to photograph or record
Photograph or record Photograph the droppings, or the soiled rear if there is diarrhoea, beside a coin for scale, Photograph the belly and the skin over the shoulders, to show fullness and hydration, and Film 10 seconds of the rabbit at rest and, if it will, attempting to eat in good, even light. Clear, well-framed evidence is what lets a vet - or a PetLumen scan - judge the change instead of guessing from a description. The checklist below is the exact shot list.
- Photograph the droppings, or the soiled rear if there is diarrhoea, beside a coin for scale
- Photograph the belly and the skin over the shoulders, to show fullness and hydration
- Film 10 seconds of the rabbit at rest and, if it will, attempting to eat
- Write down every weight in grams with the time
- Note the exact food and milk replacer, including the brand and the dilution used
Likely causes
The causes vets consider first for this presentation are diarrhoea and gut infection, overfeeding or the wrong milk, weaning stress, and gut stasis. Most are manageable once identified, but they look similar from the outside, which is why a photo-based triage and, when needed, an exam matter more than guesswork.
Diarrhoea and gut infection
Young rabbits dehydrate quickly and runny stool at this age is described as life-threatening. This is the cause that decides the timing of your call.
Overfeeding or the wrong milk
Hand-rearing errors, including cow's milk and too much at a feed, are described as a leading cause of death in orphan kits.
Weaning stress
A diet change, a new home and a lost litter all land at once around weaning, and any one of them can stop a young rabbit eating.
Gut stasis
The same gut slowdown adults get, moving faster. No droppings plus no food is an emergency at any age.
Dental or mouth problems
Malocclusion shows early in some rabbits. A young rabbit that wants food but cannot manage it needs its mouth examined.
Cold
A chilled kit cannot digest. Warming comes before feeding, and a cold, limp kit is a same-hour emergency.
Safe home care
For mild cases, safe home care is warmth first, slowly, using a covered heat pad or a wrapped bottle the rabbit can move away from, unlimited grass hay and the exact food the rabbit was already eating, and keep siblings together for warmth and comfort while you arrange the visit. These steps comfort and monitor; they do not treat the underlying cause. Stop home care and call a vet if anything in the urgent list above appears or the trend moves the wrong way.
- -Warmth first, slowly, using a covered heat pad or a wrapped bottle the rabbit can move away from
- -Unlimited grass hay and the exact food the rabbit was already eating
- -Keep siblings together for warmth and comfort while you arrange the visit
- -Weigh in grams at every feed and keep the list on your phone
- -Take the milk replacer, the food and your weight notes to the appointment
- -No cow's milk, no diet changes, and no syringe feeding beyond what a vet has instructed

When it is not an emergency
Not every worrying sign needs an out-of-hours visit. These situations are usually safe to watch at home, as long as eating, drinking and droppings stay normal and nothing in the urgent list above appears.
- ●Nest kits that are warm, round-bellied and quiet, with a doe you never catch feeding them. Once or twice in 24 hours is her normal pattern
- ●A weaned rabbit picking at treats but eating hay steadily, with normal droppings
- ●Soft clustered caecotrophs eaten straight from the rear, which are normal digestion rather than diarrhoea
- ●A first-day dip in appetite after a move, with a stable weight on the scale and normal droppings
Frequently asked
How often do baby rabbits feed?
A doe usually nurses her kits only once, and occasionally twice, in 24 hours, per the Royal Veterinary College hand-rearing guide. Never seeing a feed does not mean the kits are being neglected.
Is diarrhoea in a baby rabbit an emergency?
Yes. Runny stool in an infant or juvenile rabbit is described by rabbit-health authors as life-threatening and needing immediate veterinary care, because dehydration at that size moves very fast.
Can I give a baby rabbit cow's milk?
No. Use only what a vet or a hand-rearing guide specifies, and follow the amount exactly: overfeeding is described as a leading cause of death in hand-reared kits.
When do baby rabbits start eating solid food?
Kits typically stay in the nest for around three weeks, then emerge fully furred and begin eating solids alongside milk. Keep unlimited grass hay available from then on.
Should I move a nest of kits I think are being ignored?
Usually not. Warm, plump, quiet kits are being fed on the doe's once-a-day pattern. Only act if a kit is cold, limp, wrinkled or crying, and then call a vet.
