GI Stasis in Rabbits: The #1 Emergency
GI stasis is the most common rabbit emergency. Learn the warning signs, why a rabbit not eating for 12 hours needs a vet fast, treatment, and prevention.
If there is one rabbit emergency every owner should know by heart, it is gastrointestinal stasis. Often shortened to GI stasis or simply stasis, it is the single most common life-threatening problem in pet rabbits, and it can turn serious frighteningly fast. The good news is that it is very treatable when caught early, and much of the time it is preventable. This guide will help you recognize it, act quickly, and build a daily routine that keeps your bunny's gut moving the way nature intended.
Please read this one before you ever need it. Rabbits are prey animals, and they are remarkably good at hiding how sick they feel. By the time a rabbit looks obviously unwell, the situation is often already urgent. Knowing the signs ahead of time, and knowing that a rabbit not eating for 12 hours is an emergency, is one of the kindest things you can do as an owner.

If You See This, Call Your Vet Now
A rabbit that has not eaten or passed droppings in 12 hours, is hunched and pressing its belly down, grinds its teeth in pain, or feels cold on the ears needs a same-day exotic-vet exam. Stasis can be fatal within a day or two. When in doubt, make the call.
What GI Stasis Actually Is
A rabbit's digestive system is built to be in near-constant motion, processing a steady stream of fibrous hay from one end to the other. The muscular waves that push food along are called gut motility. In GI stasis, that motility slows down or stops. Food and fluid stop moving, the contents of the stomach and gut begin to dry out and compact, and gas-producing bacteria multiply in the stalled material. The result is a painful, bloated, distressed rabbit whose gut has essentially ground to a halt.
It is important to understand that stasis is usually a symptom, not the root illness. Something else stops the rabbit from eating first, and the stilled gut follows. That is why your vet will work to find and treat the underlying trigger, not just restart the appetite. Without addressing the cause, stasis tends to come back.
Why It Happens
Almost anything that makes a rabbit feel unwell or stop eating can set off the stasis cycle. The most common culprits include:
- Pain: Dental disease and molar spurs, gas, a bladder problem, or arthritis can all make eating hurt.
- Wrong diet: Too little long-strand hay and too many pellets, treats, or sugary snacks deprive the gut of the fiber it needs to keep moving.
- Dehydration: Not enough water dries out the gut contents and makes them hard to pass.
- Stress: A move, a new pet, loud noise, or the loss of a bonded partner can be enough to shut down appetite.
- Lack of exercise: Rabbits kept in small spaces without daily run time have sluggish guts.
- Illness or pain elsewhere: Any underlying disease that makes a rabbit feel off can be the first domino.
Notice how many of these are about pain and diet. Those two themes run through almost every case of stasis, which is also why dental health and a hay-first diet are such powerful preventives.

The Warning Signs
Learn these by heart, because early recognition saves lives. A rabbit slipping into stasis may show:
- Loss of appetite: Refusing hay first, then pellets, then even favorite greens and treats.
- Fewer or smaller droppings: Tiny, hard, misshapen pellets, droppings strung together with fur, or none at all.
- A hunched posture: Sitting tight in a corner, belly pressed to the floor, unwilling to move.
- Tooth grinding: Loud, repetitive grinding is a sign of significant pain, not contentment.
- Cold ears: Ears that feel cool can signal a dropping body temperature, a worrying sign.
- A too-quiet or gurgling belly: A silent gut, or one making loud gas sounds, both point to trouble.
- Lethargy and hiding: A normally curious rabbit that becomes withdrawn and still.
The single most reliable early flag is appetite. A rabbit that turns down a piece of cilantro, banana, or its usual favorite is telling you something is wrong. Trust that signal.
What Your Vet Will Do
At the clinic, an exotic or rabbit-savvy vet will examine your rabbit, often feeling the abdomen and sometimes taking x-rays to distinguish a slowed gut from a true blockage, which is a different and even more urgent situation. Typical treatment includes:
- Pain relief: Controlling pain is essential, both for comfort and because pain itself suppresses gut movement.
- Fluids: Given under the skin or into a vein to rehydrate the dried gut contents.
- Motility drugs: Medications that encourage the gut to start moving again, used only once a blockage has been ruled out.
- Assist feeding: Syringe-feeding a high-fiber recovery formula to keep nutrients and fiber flowing.
- Treating the cause: Addressing the dental problem, gas, or stress that started it all.
Most rabbits caught early do very well. The difference between a good and a bad outcome is usually how quickly the rabbit is seen.
Supporting Recovery at Home
Once your vet has examined your rabbit and ruled out an obstruction, home care plays a big role. Your vet may have you continue syringe-feeding a recovery formula several times a day, encourage gentle exercise, and offer water-rich greens to boost hydration. Simethicone, the same gentle gas remedy sold for human infants, is often recommended to relieve painful gas bubbles. Keep your rabbit warm, calm, and close to its hay, and follow your vet's medication schedule closely. Never give belly massage or fluids on your own if a blockage has not been ruled out.
Preventing the Next Episode
Stasis prevention is daily rabbit care done well. Build your routine around these pillars:
- Hay first, always: Unlimited grass hay should be roughly 80 percent of the diet. It wears teeth down and keeps the gut moving.
- Measured pellets, generous greens: A small daily portion of quality pellets and a varied salad of leafy greens, with treats kept tiny and occasional.
- Fresh water always available: A bowl often encourages more drinking than a bottle.
- Daily exercise: Several hours of run-around time in a rabbit-proofed space keeps the gut active.
- Routine dental checks: Since hidden tooth pain is a top trigger, have your vet check the molars regularly.
- Weekly weigh-ins: A gram scale catches slow weight loss before it becomes a crisis.
- A calm home: Minimize stress and introduce changes gradually.
None of this replaces veterinary care, and this guide is educational rather than a substitute for your vet. But an owner who knows the signs, keeps a simple care kit on hand, and feeds a true hay-first diet gives their rabbit the best possible protection against the most common rabbit emergency there is.

Frequently Asked Questions
Is GI stasis in rabbits an emergency?
Yes. Gastrointestinal stasis is the most common life-threatening emergency in pet rabbits, and it can become fatal within a day or two if it is not treated. A rabbit that has not eaten for 12 hours or has stopped producing droppings needs to be seen by a rabbit-savvy or exotic vet right away, ideally the same day. Because rabbits hide illness so well, by the time you notice something is wrong the slowdown is often already advanced, so do not wait to see if it passes on its own.
What causes GI stasis in rabbits?
Stasis is almost always a symptom of another problem rather than a disease by itself. Common triggers include pain (often from dental disease, gas, or a urinary issue), stress, a diet too low in long-strand hay and too high in pellets or treats, dehydration, and lack of exercise. Anything that makes a rabbit stop eating can start the cycle: when the gut slows, gas and bad bacteria build up, which causes more pain, which further reduces appetite. Finding and treating the underlying cause is just as important as restarting the gut.
How can I tell if my rabbit has GI stasis?
The classic signs are a rabbit that stops eating, stops or dramatically reduces droppings, and sits hunched in a corner pressing its belly to the floor. Droppings may become tiny, misshapen, or strung together with fur. The rabbit may grind its teeth loudly in pain, feel cold to the touch on its ears, and seem withdrawn or reluctant to move. A gut that is too quiet or, conversely, makes loud gurgling gas sounds are both warning signs. Any rabbit refusing its favorite food needs attention.
Can I treat rabbit GI stasis at home?
Mild early slowdowns are sometimes turned around at home with extra hydration, gentle belly massage, exercise, and tempting fresh greens, but this is only safe once a vet has ruled out a blockage. Never give belly massage or force fluids if a full intestinal obstruction is possible, because that can be dangerous. Home care like syringe-feeding a recovery formula and offering simethicone for gas is best done under veterinary guidance. When in doubt, the safest choice is always a same-day exam rather than waiting.
What does the vet do for GI stasis?
Treatment usually includes pain relief, fluids to rehydrate the gut contents, and medications that encourage normal gut movement once an obstruction has been ruled out by exam and sometimes x-rays. The vet will also syringe-feed a high-fiber recovery formula and look for the underlying cause, whether that is a painful tooth, gas, or stress. Most rabbits caught early recover well. The key is speed: prompt veterinary care dramatically improves the odds compared to waiting and hoping the appetite returns.
How do I prevent GI stasis in my rabbit?
Prevention comes down to a hay-first lifestyle. Unlimited grass hay should make up around 80 percent of the diet, with a measured portion of pellets, a daily salad of leafy greens, and treats kept tiny. Provide plenty of space and daily exercise, fresh water at all times, regular dental checks, and a low-stress home. Weigh your rabbit weekly to catch slow weight loss early, and learn what normal droppings and appetite look like so you notice the first hint of a problem fast.
How long can a rabbit go without eating before it is dangerous?
A healthy rabbit grazes almost constantly, so even a short fast is abnormal. As a rule of thumb, going 12 hours without eating or without passing droppings is a genuine emergency that warrants a call to your vet, and after 24 hours the risk of serious complications climbs sharply. Do not adopt a wait-and-see approach overnight. If your rabbit skips breakfast and shows no interest in a favorite green or herb, treat it as urgent rather than assuming it is being picky.
