How to Quickly Detect GI Stasis in Rabbits (and what to do about it)

Your rabbit stops eating, pooping, and hopping around. He starts hiding and hunching over in pain. His belly gurgles loudly or lies scarily still and swollen. You panic, realizing something is terribly wrong with your beloved bunny. Gastrointestinal stasis has struck, a potentially fatal condition where the gut shuts down. Your rabbit’s life may now hang in the balance. Quick action is critical! Familiarize yourself with the symptoms, causes, and emergency response steps for GI stasis so you can recognize it early and race your rabbit to the vet ASAP. With rapid expert care, most bunnies fully recover. Stay vigilant – know how to detect and combat stasis before it’s too late! Your rabbit is relying on you.

What is GI Stasis?

Gastrointestinal (GI) stasis, also known as ileus, is a serious condition that occurs when a rabbit's gastrointestinal tract slows down or stops completely. This results in a buildup of gas, fluid, and ingested food material that cannot pass through the system properly. GI stasis is one of the most common gastrointestinal issues in domestic rabbits and can become life-threatening very quickly if not treated.

Rabbits are hindgut fermenters, meaning their digestive system relies heavily on maintaining forward motility of food through the gut in order to function properly. When this forward motion slows or stops, bacteria and toxins can accumulate and cause dangerous systemic issues. Catching the early signs of GI stasis and taking prompt action is critical for recovery.

Some key things to understand about GI stasis in rabbits:

  • It indicates a disruption of normal intestinal motility and forward passage of contents. Food, fluid, and gas get "stuck" in the GI tract.

  • It can range from mild transient slowing to complete blockage and ileus.

  • It is not a disease itself but rather a clinical sign of an underlying problem. Identifying and treating the cause is important.

  • GI stasis leads to a dangerous buildup of gas, fluid, and toxins that can poison the body. It can become life-threatening within 12-24 hours without treatment.

  • Common causes include diet issues, stress, pain from another condition, intestinal blockages, infections, hypothermia, and certain medications.

  • Smaller rabbits under 6 months old and senior rabbits are at higher risk. But GI stasis can affect rabbits of any breed, age, or gender.

  • Aggressive, prompy supportive therapy by a rabbit-savvy vet is crucial. Rabbits are experts at hiding illness until it's advanced.

  • Prevention focuses on providing excellent diet, limiting stress, identifying and treating sources of pain, and maintaining normal gut motility daily.

GI stasis is a veterinary emergency requiring rapid diagnosis and treatment. Rabbits experiencing stasis are frequently quite ill. Catching it early and getting veterinary help right away provides the best chance of recovery. Don't delay if your rabbit is showing any signs of possible GI problems.

Symptoms of GI Stasis

Rabbits experiencing GI stasis may display a variety of symptoms. Early detection and rapid treatment are critical, as rabbits can deteriorate quickly once stasis begins. Here are some of the most common signs of possible GI stasis:

Not eating

One of the first and most obvious symptoms of GI problems is a reduction or complete stop in eating.

Rabbits are nearly continuous grazers and typically have a strong appetite. When they start refusing foods they normally enjoy, it signals an issue.

Any anorexia or disinterest in treats lasting over 12 hours warrants an urgent vet visit. Abdominal pain from stasis causes loss of appetite. But not eating also exacerbates the problem too.

Closely monitor appetite and eating patterns. Note any changes early.

Not pooping

Healthy rabbits produce regular, round, uniform fecal pellets. These should be passed frequently all day as the rabbit eats continuously.

When GI motility slows, rabbits stop passing stool normally. You may see no poop at all or only occasional small, misshapen pellets.

Lack of poop for over 12 hours indicates a major problem. Seek emergency vet care.

Also note if cecotropes (soft nutrient pellets) are not being produced or eaten normally. This is another red flag.

Lack of energy

Rabbits are typically quite active, especially in the evenings. But lethargy or suddenly lying around for hours signals illness.

GI stasis causes abdominal discomfort, nausea, weakness and malaise. Your bunny may have little interest in normal activities.

While all rabbits have quiet moments, dramatic or sustained drops in energy warrant a vet visit.

Hunched posture

Rabbits in pain from GI issues often sit in a hunched posture with the belly pressed to the floor. They resist touching or palpating the abdomen.

Hunching can also indicate breathing trouble from gas buildup. This requires urgent vet attention.

Do not dismiss hunching as normal resting behavior. Check immediately with a vet.

Loud stomach gurgles or none at all

Slowed GI motility leads to gas buildup and loud gurgling sounds coming from the stomach. The belly may also feel enlarged or tight like a balloon.

But sometimes stasis blocks even these sounds. Absence of normal loud intestinal noises over 12-24 hours is problematic.

Monitor your rabbit's belly for changes in noises, shape, or feel indicating trapped gas.

Unusual behavior for your rabbit

In addition to appetite and poop changes, sick rabbits often act differently than normal.

Your rabbit may become withdrawn and inactive when usually playful. Or show unusual aggression or vocalizations indicating pain.

Get to know your individual bunny's normal behavior. Subtle personality changes can signal illness before it becomes severe.

Mushy or unformed cecotropes

Cecotropes are the soft, pungent, nutrient-packed stools rabbits normally eat directly from their rectum. These should have a formed shape.

GI issues lead to abnormally loose, mushy, or shapeless cecotropes. Your rabbit likely won't consume these.

Monitor the consistency and your rabbit's interest in cecotropes. Irregularities indicate GI problems.

Small or double poops

Healthy fecal pellets are round, separate, and uniformly sized. But GI dysfunction leads to tiny pebbles, connected or double poops.

This happens when transit time speeds up to try to clear blockages. The intestines don't form stools properly.

Tiny or irregular poops lasting over 12 hours require prompt veterinary diagnosis. Monitor your rabbit's output.

If you notice any combination of the above symptoms, seek veterinary care immediately. GI stasis can become fatal very rapidly. Bring your rabbit in without delay for evaluation and treatment.

Causes of GI Stasis

There are a variety of possible reasons a rabbit's GI tract may slow down or stop. Identifying the underlying cause is key to proper treatment and prevention. Causes may include:

An unhealthy diet

Improper nutrition is one of the most common contributors to GI stasis. Rabbits have very delicate digestive systems requiring a balanced high fiber diet.

Too many pellets, sugary treats, or inappropriate foods leads to disruptions. Insufficient hay intake is also problematic.

Work closely with an exotics vet to tailor the ideal everyday diet plan for your bunny. Focus on unlimited grass hay.

Other injuries or illnesses

Any condition causing pain or discomfort can indirectly lead to GI slowdown. Common examples include dental disease, urinary tract infections, arthritis, abscesses, or respiratory infections.

Identify and treat any other ongoing health issues to alleviate systemic stress on digestion. Manage pain and inflammation appropriately.

Stress or anxiety

Emotional issues like a frightening situation or disruption to home environment can impact sensitive rabbit digestion.

Minimize stressors like loud noises, predators, travel, solo living, or children's mishandling. Rabbits do best with a stable, peaceful environment and companion.

Use pheromone sprays, soothing music, hides, and routines to reduce anxiety. Monitor after any stressful events.


Rabbits have high fluid requirements. Dehydration from insufficient water intake concentrates gastrointestinal contents and slows motility.

Ensure unlimited access to clean drinking water daily. Change water dishes frequently and rinse thoroughly.

Offer hydrating vegetables like cucumbers. In warm weather, use frozen water bottles and tiles to encourage drinking.

Intestinal blockage

Foreign objects like carpet fibers, packaging, or ingested toys can obstruct the intestines. This causes a dangerous backup.

Rabbit-proof your home to remove hazards. Watch for evidence of blockage like small, painful poops or lack of output. Seek emergency vet diagnosis and removal.


Excess weight stresses the entire body including the GI system. Overweight rabbits are more prone to GI statis, especially when coupled with poor diet.

Maintain your rabbit at optimal body condition through measured pellet rations, ample exercise, and vet wellness checks. Support healthy digestion and motility.


Some rabbits are genetically prone to ileus based on selective breeding. Dwarf breeds and rabbits with short facial structures tend to be most at risk.

Ask your veterinarian to suggest breeds with lower GI sensitivity. Provide extra diligence with diet and stress reduction for vulnerable rabbits. Stay alert to early signs of problems.

The most effective way to prevent GI stasis is to optimize your rabbit's diet, environment, exercise, and veterinary care. Focus on steady, ample hay consumption, plenty of water, and minimal stresses. With prompt treatment when signs arise, most rabbits recover well and avoid recurrences. Stay alert to subtle appetite or behavior changes that may indicate GI disruptions before they become severe. Partner closely with an experienced rabbit vet for the healthiest digestion and happiest bunny.

What to Do If You Suspect GI Stasis

If your rabbit is displaying any symptoms that may indicate GI stasis, take the following steps immediately:

  • Withhold food, treats, and supplements until seen by a vet. Provide unlimited timothy or orchard grass hay.

  • Give simethicone anti-gas medication if gurgling, tight belly, or hunching is seen. Follow product dosing instructions carefully. Massage the belly gently to help dissipate gas bubbles.

  • Offer small amounts of tepid water frequently via syringe or bowl to encourage fluid intake. Electrolyte solutions help replenish losses.

  • Do not give over-the-counter human medications unless specifically recommended by your vet. What is safe for people can be toxic to rabbits.

  • Check for normal body temperature. Hypothermia is dangerous. Use supplemental heat sources if below 101 F.

  • Get your rabbit examined by an experienced exotics vet immediately. Waiting or trying home remedies risks serious progression and complications.

  • Be prepared to leave your rabbit for in-clinic diagnostics, possible x-rays to check for blockages, and initial treatment including IV fluids and motility drugs.

  • Expect prescribed medications to take home including GI motility aids, pain relievers, probiotics, appetite stimulants, and/or antibiotics. Follow dosing carefully.

  • Assist with syringe feeding recovery food as appetite returns. Give fresh greens in limited amounts at first. Gradually return to normal hay diet over 2-3 days.

  • Be diligent with follow up exams to check recovery progress and determine any needed diet or lifestyle changes to prevent recurrence.

GI stasis should be treated as a veterinary emergency requiring professional diagnosis and appropriate medical care. With rapid action, most rabbits recover fully and avoid lasting GI problems. Stay alert to signs of trouble and never hesitate to call your vet if concerned. Proper diet, hydration, exercise, and stress reduction also support healthy ongoing digestion.
