You notice your rabbit is sitting hunched in a corner. Her belly looks bloated. She is not eating. She is not pooping. You have a rabbit showing signs of digestive distress. Gas and bloating in rabbits can be a sign of gastrointestinal stasis, a life-threatening emergency.
According to the RSPCA, gastrointestinal stasis is one of the most common and serious conditions in pet rabbits. The House Rabbit Society emphasizes that any rabbit showing signs of gas or bloating needs immediate veterinary attention. An affected rabbit can deteriorate rapidly without treatment.
This guide covers everything about rabbit gas and GI stasis: why rabbits get gas, how to recognize GI stasis, treatment options, and prevention strategies. For general illness signs, see sick bunny. For appetite loss and digestive issues, see why is my rabbit not eating.
Gas and bloating in rabbits can be a sign of gastrointestinal stasis, a life-threatening emergency. Symptoms include bloating, not eating, and not pooping. Immediate veterinary care is essential.
Do Rabbits Pass Gas
Do rabbits pass gas? Yes, rabbits can and do pass gas. However, unlike humans and some other animals, rabbits are not designed to pass large amounts of gas. Their digestive system produces gas as a normal byproduct of fermentation, but excessive gas is a sign of a problem.
Rabbits have a unique digestive system. Food passes through the stomach and small intestine into the cecum, a large pouch where bacteria ferment fiber. This fermentation produces gas. Normally, this gas is passed without issue. When the digestive system slows down, gas builds up, causing pain and bloating.
According to veterinary sources, a rabbit with excessive gas is showing signs of digestive distress. Gas buildup and GI stasis often reinforce each other. Slowed gut movement allows gas to accumulate, which causes pain that further slows motility. This is why prompt veterinary attention is essential for any rabbit with significant gas or bloating.

Why Is My Rabbit Gassy
Why is my rabbit gassy? Several factors can cause gas buildup in rabbits. Understanding these factors helps you prevent digestive problems.
Dietary issues: A diet too low in fiber or too high in carbohydrates can cause gas. Too many pellets, sugary treats, or starchy vegetables can disrupt the gut bacteria, leading to gas production. A sudden change in diet can also cause digestive upset.
Stress: Stress can slow digestion. Changes in environment, loud noises, new pets, or routine changes can cause stress-related digestive problems.
Pain or illness: Pain from dental disease, injury, or other illness can slow digestion. A rabbit in pain may not eat or move enough to keep the digestive system working.
Dehydration: A rabbit that is not drinking enough water can develop digestive problems. Dehydration makes droppings hard and dry, slowing gut movement.
Dental disease: Dental pain can prevent a rabbit from eating enough hay. Without enough fiber, the digestive system slows down. For more on dental issues, see malocclusion in rabbits.
Gut imbalance: An imbalance in gut bacteria can cause excessive gas. This can result from diet changes, stress, or antibiotic use.
Common causes of gas in rabbits include low-fiber diet, stress, pain, dehydration, dental disease, and gut imbalance. Identifying the cause is essential for treatment.
Rabbit Digestive System Explained
Understanding the rabbit digestive system helps you recognize why gas becomes dangerous. Rabbits have a unique digestive system designed for processing large amounts of fiber.
The digestive system starts with the mouth and stomach. Food passes into the small intestine, where nutrients are absorbed. Then it moves into the cecum, a large pouch where bacteria ferment fiber. This fermentation produces gas and nutrients. The cecum produces cecotropes, soft droppings that rabbits eat for nutrition.
The rabbit digestive system requires constant movement. Food must pass through the digestive tract continuously. When the system slows, gas builds up, and the rabbit shows signs of digestive distress. According to veterinary sources, the cecum is particularly sensitive to changes in diet and stress.

The rabbit digestive system requires constant movement. The cecum ferments fiber, producing gas. When digestion slows, gas builds up, causing pain and further slowing motility.
Gastrointestinal Stasis Overview
Gastrointestinal stasis, or GI stasis, is a life-threatening condition where the digestive system slows or stops. According to the Cornell University College of Veterinary Medicine, GI stasis is one of the most common and serious conditions in pet rabbits.
In GI stasis, the digestive system slows down. Food sits in the gut, ferments, and produces gas. The gas causes bloating and pain. The rabbit stops eating and pooping. GI stasis can become life-threatening within hours if left untreated.
GI stasis is not a disease itself. It is a symptom of an underlying problem. Common causes include low fiber diet, stress, pain, and dehydration. Slowed gut movement allows gas to accumulate, which causes pain that further slows motility. This cycle is why prompt veterinary care is essential.
GI stasis is a life-threatening condition where the digestive system slows down. It can become life-threatening within hours if left untreated. Gas and GI stasis often reinforce each other.
What Causes GI Stasis in Rabbits
Understanding what causes GI stasis in rabbits helps you prevent it.
Low fiber diet: The most common cause of GI stasis is a diet low in fiber. Hay is essential for digestive health. Without enough hay, the digestive system slows down. According to the Humane Society, a hay-based diet prevents most digestive problems.
Stress: Stress can slow digestion. Changes in environment, loud noises, new pets, or routine changes can cause stress-related GI stasis.
Dehydration: A rabbit that is not drinking enough water can develop GI stasis. Dehydration makes droppings hard and dry, slowing gut movement.
Dental disease: Dental pain can prevent a rabbit from eating enough hay. Without enough fiber, the digestive system slows down.
Pain: Any pain, from injury or illness, can affect digestion. A rabbit in pain may not eat or move enough to keep the digestive system working.
Gut imbalance: An imbalance in gut bacteria can cause GI stasis. This can result from diet changes, stress, or antibiotic use.
Common causes of GI stasis include low fiber diet, stress, dehydration, dental disease, pain, and gut imbalance. A hay-based diet prevents most digestive problems.
Early Warning Signs of GI Stasis
Recognizing the early warning signs of GI stasis helps you seek treatment before it becomes life-threatening.
Rabbit not pooping: A decrease in droppings is the most obvious sign. A rabbit producing few or no droppings, particularly alongside reduced appetite, lethargy, or abdominal pain, should be seen urgently by a rabbit-savvy veterinarian.
Appetite loss: A rabbit that stops eating or eats less may have GI stasis. Loss of appetite with other symptoms requires veterinary attention.
Lethargy: Lethargy is a common sign of illness. A rabbit that is less active or sleeps more than usual may have GI stasis.
Bloating: A rabbit may have a visibly enlarged abdomen. The rabbit may show signs of discomfort and reluctance to move.
Pain symptoms: A rabbit in pain may grind teeth, sit hunched, or be reluctant to move. Pain with other symptoms requires immediate attention.
Small droppings: The droppings may be smaller than usual. They may be irregular in shape or size. Small droppings indicate reduced food intake or slowed digestion.
For more on recognizing a sick bunny, see sick bunny.
Emergency warning: A rabbit producing few or no droppings, particularly alongside reduced appetite, lethargy, or abdominal pain, should be seen urgently. Do not wait to see if they improve.
GI Stasis Poop Changes
Monitoring your rabbit's droppings is one of the most important things you can do. Changes in poop are often the first sign of a problem.
Rabbit not pooping: A rabbit producing very few or no droppings needs urgent assessment.
Small droppings: Droppings that are smaller than normal indicate reduced food intake or slowed digestion.
Misshapen droppings: Droppings that are irregular in shape or size indicate poor digestion. This can indicate dental problems, dietary imbalance, or gastrointestinal slowdown.
Reduced fecal output: A decrease in the total number of droppings is a warning sign. Healthy rabbits produce a consistent amount daily.
Abnormal droppings: Droppings that are soft, sticky, or stuck together indicate digestive upset.
For more on droppings, see healthy bunny poop.
What this means for you: Poop changes in GI stasis include no droppings, small droppings, misshapen droppings, reduced output, and abnormal droppings. Any change requires attention.
Treatment for GI Stasis
Treatment for GI stasis requires immediate veterinary care. While travelling to the vet, you can keep your rabbit warm, offer fresh hay and water, and encourage gentle movement if appropriate. Do not attempt to treat GI stasis at home without veterinary guidance.
Emergency care: GI stasis is a medical emergency. Contact your veterinarian immediately. Do not wait to see if your rabbit improves.
Veterinary treatment: Your vet will examine your rabbit and may recommend fluid therapy, pain relief, and gut motility drugs. In severe cases, hospitalization may be necessary.
Fluid therapy: Dehydration is common with GI stasis. Your vet may give fluids subcutaneously or intravenously.
Pain relief: Pain medication is essential. A rabbit in pain cannot recover.
Critical care feeding: Your vet may recommend syringe feeding a recovery food like Critical Care, only if recommended by your veterinarian. This provides nutrition and stimulates gut movement.
Recovery care: After treatment, monitor your rabbit closely. Follow your vet's instructions for home care.

Veterinary tip: While travelling to the vet, keep your rabbit warm, offer fresh hay and water, and encourage gentle movement if appropriate. Do not attempt home treatment without veterinary guidance.
When It Becomes an Emergency
Knowing when to seek emergency care saves lives. Some signs require immediate veterinary attention.
Not eating: A rabbit that stops eating needs emergency care. Loss of appetite with other symptoms is serious.
Not pooping: A rabbit producing few or no droppings, particularly alongside reduced appetite, lethargy, or abdominal pain, should be seen urgently.
Severe bloating: A rabbit with a visibly enlarged abdomen needs urgent care. Bloating indicates gas buildup.
Collapse: If your rabbit has collapsed or cannot stand, this is an emergency. Seek immediate veterinary care.
Pain symptoms: A rabbit in pain may grind teeth, sit hunched, or be reluctant to move. Pain with other symptoms requires immediate attention.
Critical illness: A rabbit that is lethargic, unresponsive, or showing signs of severe illness needs emergency care.
Emergency warning: A rabbit with not eating, not pooping, severe bloating, collapse, or pain symptoms needs immediate veterinary care. Do not wait.
How to Prevent GI Stasis
Preventing GI stasis is easier than treating it. Good care reduces the risk of digestive problems.
Unlimited hay: Hay should be 80-90% of the diet. Timothy hay is best for adults, and orchard grass is another good option. Hay provides the fiber needed for healthy digestion.
Healthy diet: Unlimited hay, fresh greens, and limited pellets. Avoid sugary treats. Introduce new foods gradually.
Fresh water: Fresh water must be available at all times. Dehydration causes digestive problems.
Exercise: Several hours of daily exercise help maintain digestive health. A rabbit that moves freely is less likely to develop GI stasis.
Stress reduction: Provide a calm environment. Handle gently. Give hiding places. Keep other pets away.
Dental care: Annual dental checks by a rabbit-savvy vet are essential. Dental problems cause GI stasis. For more on dental issues, see rabbit teeth.
