Why Is My Rabbit Not Eating?

If your rabbit is not eating, don’t wait to see if it gets better. A rabbit not eating is often one of the earliest signs of serious illness and should be evaluated by a veterinarian as soon as possible.

Unlike dogs and cats, rabbits rely on a constant intake of food to keep their digestive tract moving. When a rabbit develops an underlying illness, they often eat less, which can contribute to gastrointestinal (GI) stasis—a clinical syndrome in which the digestive tract slows down or stops moving normally. Because GI stasis is often the result of another medical condition, prompt veterinary evaluation is essential to identify and treat the underlying cause.

Key Takeaway: A rabbit not eating is never normal. Even a decreased appetite or fewer droppings can be an early sign of serious illness and should be evaluated by a veterinarian as soon as possible.

What Causes a Rabbit to Stop Eating?

There are many reasons a rabbit may stop eating, and identifying the underlying cause is essential. One of the most common clinical syndromes associated with a rabbit not eating is gastrointestinal (GI) stasis. GI stasis is not a specific disease, but rather a slowdown or complete cessation of the normal movement of the digestive tract that can result from a variety of underlying medical conditions.

Common causes that can lead to GI stasis or a decreased appetite include:

• Dental disease or overgrown teeth
• Pain or injury
• Stress or sudden environmental changes
• Dehydration
• An inappropriate diet (too many treats or not enough hay)
• Intestinal blockage (foreign material)
• Infection or other illnesses
• Liver or kidney disease

When rabbits experience one of these underlying problems, the digestive tract can begin to slow down. As food and gas accumulate, the rabbit becomes increasingly uncomfortable and eats even less, creating a dangerous cycle that can quickly become life-threatening if left untreated. Because GI stasis is a sign of an underlying problem—not the problem itself—it’s important for your veterinarian to identify and treat the underlying cause.

Signs Your Rabbit May Have GI Stasis

If your rabbit is showing any of the following signs, contact your veterinarian promptly:

• Refusing hay, pellets, or favorite treats
• Eating less than usual
• Smaller, fewer, or no droppings
• Hunched posture
• Grinding teeth due to pain
• Lethargy or decreased activity
• A bloated or firm abdomen
• Hiding more than usual

When Is It an Emergency?

A healthy rabbit should eat throughout the day and night. A rabbit that has completely stopped eating should be considered an emergency. Unlike people or some other pets, rabbits do not typically skip meals because they “aren’t hungry.” If your rabbit is not eating, has a decreased appetite, or is producing fewer droppings than normal, it’s important to contact your veterinarian promptly.

Seek veterinary care immediately if your rabbit:

• Has not eaten for several hours or refuses all food
• Produces very few or no droppings
• Appears lethargic or weak
• Has a swollen or painful abdomen
• Is grinding its teeth due to pain
• Is having difficulty moving or sitting hunched over

Even if your rabbit is still drinking water or nibbling on treats, a decreased appetite is not normal and should not be ignored. Rabbits often continue eating small amounts even when they are becoming seriously ill.

Prompt veterinary care is critical, as rabbits can become seriously ill in a short period of time.

What Should I Do While Waiting for My Appointment?

Until your rabbit can be examined:

• Keep fresh grass hay available at all times.
• Offer fresh water.
• Monitor appetite and the number of droppings.
• Keep your rabbit warm and in a quiet, low-stress environment.

Do not force-feed your rabbit or give over-the-counter medications unless directed by a veterinarian. If an intestinal blockage is present, force-feeding can worsen the situation.

Can GI Stasis Be Prevented?

While not every case can be prevented, you can reduce your rabbit’s risk by:

• Providing unlimited grass hay
• Feeding a balanced, species-appropriate diet
• Scheduling regular veterinary wellness exams
• Monitoring eating habits and droppings daily
• Addressing dental disease and other medical conditions early
• Reducing stress whenever possible

Frequently Asked Questions

How long can a rabbit go without eating?

Rabbits should not go long without eating. Even several hours without food can become concerning because their digestive system depends on a constant intake of fiber to function normally.

My rabbit is eating treats but not hay. Is that okay?

No. A rabbit that suddenly refuses hay may be experiencing dental pain or another medical problem. Because hay is the foundation of a rabbit’s diet, this change should not be ignored.

My rabbit is eating less but still drinking. Should I wait?

Even if your rabbit is still drinking water, a decreased appetite is not normal and should be discussed with your veterinarian as soon as possible.

Will GI stasis go away on its own?

No. GI stasis requires prompt veterinary evaluation to identify the underlying cause and begin appropriate treatment. Waiting can allow the condition to worsen.
