GI stasis (gastrointestinal stasis) is one of the most common emergencies in pet rabbits. It means the gut has slowed down or stopped moving. Because a rabbit's digestive system depends on constant movement, things can go downhill quickly.
The University of Illinois College of Veterinary Medicine describes it as a condition that can rapidly become life threatening if left untreated. The good news is that rabbits treated early often recover well.
The warning signs
Rabbits hide illness, so the first signs are often small. Check these every day:
| Sign | What to look for |
|---|---|
| Appetite | Eating less, refusing pellets or favorite treats, or ignoring hay |
| Droppings | Fewer, smaller, drier, or misshapen droppings, or none at all |
| Posture | Sitting hunched up in a ball, not wanting to move |
| Pain | Loud teeth grinding, pressing the belly to the floor |
| Belly | A tight, bloated, or gurgling belly, or a very quiet belly |
| Energy | Hiding, low energy, not interested in you |
| Other | Drooling, or a cold feel to the ears and feet |
If your rabbit has stopped eating or stopped pooping, call a vet the same day. Do not wait overnight to see if it improves.
What to do right now
- Call a rabbit savvy vet. Not every clinic treats rabbits. Look for an exotic animal vet ahead of time and save the number. If your regular vet is closed, call an emergency clinic that sees rabbits.
- Write down the details. When your rabbit last ate normally, when you last saw normal droppings, and any changes to diet, home, or routine.
- Keep your rabbit warm and quiet. A low body temperature is a bad sign in sick rabbits. Offer a soft towel in a quiet room, away from drafts.
- Offer fresh hay and water, but do not force food or water into your rabbit's mouth unless your vet shows you how.
- Bring a sample of droppings and the food your rabbit eats, if you can.
Do not give human medicines or home remedies. Some are dangerous for rabbits and can hide signs your vet needs to see.
What causes GI stasis
The Illinois vet school notes that GI stasis is always caused by something else. Common triggers include:
- Low fiber diet. Too many pellets, treats, or sugary foods and not enough hay.
- Sudden diet changes.
- Stress. Moving house, travel, loud noises, a new pet, or a vet stay.
- Pain. Dental problems are a major cause, along with arthritis, injuries, and bladder stones.
- Dehydration.
- Other illnesses, including kidney or liver disease.
- Swallowed hair, especially during heavy shedding, which can clump in the gut.
How vets treat it
Treatment depends on the cause, but often includes:
- Pain relief. Pain alone can stop a rabbit's gut from working.
- Fluids, given under the skin or into a vein, to rehydrate the body and soften gut contents.
- Syringe feeding with a special high fiber recovery food for herbivores, which helps get the gut moving again.
- Gut medicines in some cases, to help movement or protect the stomach.
- Tests such as X rays or blood work, to look for a blockage or underlying disease.
According to the Illinois guidance, treatment often lasts three to five days, and most rabbits should show improvement within 24 to 48 hours. A rabbit that does not improve may need hospital care. A true blockage is a separate, more serious problem that your vet will check for.
How to prevent GI stasis
1. Make hay the main food
The Illinois guidance recommends a diet that is more than 75 percent grass hay, such as timothy or orchard grass. Hay should be available all day, every day, in amounts about the size of your rabbit.
| Food | Daily amount (general guide for adults) |
|---|---|
| Grass hay | Unlimited, always available |
| Fresh leafy greens | A few handfuls, a mix of types |
| Plain hay based pellets | A small amount only |
| Fruit and sugary treats | Tiny amounts, a few times a week at most |
| Fresh water | Always available, in a bowl, a bottle, or both |
Ask your vet for exact amounts for your rabbit's size and age.
2. Change food slowly
Introduce any new food, including new greens or a new pellet brand, in small amounts over one to two weeks.
3. Brush during shedding season
Rabbits groom themselves and swallow hair. Brushing removes loose fur, especially during heavy molts.
4. Keep them moving
Daily time out of the enclosure to hop, explore, and play keeps the gut active.
5. Watch the droppings
Checking the litter box daily is the easiest early warning system you have. Our guide on how to litter train a rabbit makes this much easier.
6. Get yearly dental and health checks
Overgrown teeth cause pain and make eating hard. A rabbit savvy vet can spot problems early.
7. Reduce stress
Keep routines steady, give hiding spots, and introduce changes gradually.
Be ready before an emergency
GI stasis often starts at night or on weekends. A little planning saves precious time:
- Find a rabbit savvy vet now, plus a backup emergency clinic that treats rabbits. Save both numbers in your phone.
- Keep a travel carrier clean and easy to reach, lined with a towel.
- Keep your rabbit's weight on record. Weigh it monthly on a kitchen scale, because weight loss is an early warning sign.
- Keep a small notebook or phone note of normal eating and droppings, so you can spot changes and tell the vet exactly what changed.
- Ask your vet whether they want you to keep a recovery food formula and feeding syringe at home, and how to use it only under their guidance.
Being prepared means you can act within hours instead of losing a night searching for help.
The bottom line
A rabbit that stops eating or pooping is an emergency, not a "wait and see" problem. Know the signs, have a rabbit savvy vet's number ready, and act the same day. A diet built on unlimited grass hay, slow food changes, exercise, and daily poop checks is the best way to keep your rabbit's gut moving.
Frequently asked questions
How long can a rabbit go without eating?
Not long. A rabbit's gut needs a steady flow of food to keep moving. If your rabbit refuses food, including favorite treats, or stops making droppings, call a vet the same day.
Can I treat GI stasis at home?
No. GI stasis always has an underlying cause, such as pain, stress, dental disease, or a poor diet, and it needs a vet to find and treat it. Pain relief, fluids, and syringe feeding are usually needed, and they must be guided by a vet.
What do healthy rabbit droppings look like?
Healthy droppings are round, fairly large, firm but not hard, and plentiful every day. Small, dry, misshapen, or very few droppings, or droppings strung together with hair, are warning signs.
Is teeth grinding in rabbits always bad?
Soft, gentle tooth clicking while being petted can mean contentment, sometimes called tooth purring. Loud teeth grinding, especially with a hunched posture and not eating, usually means pain.
