My Rabbit Has Stopped Eating — Is It an Emergency?

If your rabbit has stopped eating, this is one situation where you should never wait and see. Unlike dogs and cats, rabbits have a highly sensitive digestive system — and even 12 hours without food can be life-threatening. Here's everything you need to know.

Why Is It So Serious? Rabbits need a constant flow of food through their gut to keep their digestive system moving. When they stop eating, the gut slows down or stops entirely — a condition called GI stasis (gastrointestinal stasis). Without treatment, GI stasis can be fatal within 24–48 hours.

What Causes a Rabbit to Stop Eating?

GI stasis — the most common and most dangerous cause
Dental problems — overgrown or misaligned teeth make eating painful
Stress — a change in environment, loud noises, or a new pet
Blockage — something obstructing the digestive tract
Pain from another source — urinary issues, injury, or infection

Warning Signs to Watch For

Not eating hay, pellets, or fresh food for more than 4–6 hours
No droppings, or very small/abnormal droppings
Hunched posture, pressing belly to the floor
Teeth grinding (sign of pain)
Bloated or hard abdomen
Lethargy or not wanting to move

What to Do Right Now

Check when they last ate and passed droppings
Offer their favourite food — fresh herbs like parsley or coriander can sometimes tempt them
Gently encourage light movement — a short supervised hop around the room can stimulate the gut
Keep them warm and calm
If they haven't eaten in 6+ hours — call a rabbit-savvy vet immediately

This Is a Vet Emergency Do not wait overnight. Do not assume they'll eat in the morning. GI stasis moves fast — a rabbit that seemed fine at dinner can be critically ill by morning. Call an emergency vet if your normal practice is closed.
