GI Stasis in Rabbits: The Silent Emergency

Rabbits Cannot Vomit -- Which Makes a Gut Slowdown Catastrophic

A dog with an upset stomach vomits. A cat vomits. A rabbit's GI anatomy does not include the muscle configuration or nervous system pathways that allow vomiting -- anything that enters the stomach moves forward, or it doesn't move at all. When gut motility drops, gas produced by bacteria in the cecum has nowhere to go. It accumulates, causes severe pain, the rabbit stops eating from pain, which reduces gut motility further, which causes more gas buildup. The cycle kills rabbits within 24-72 hours if the spiral isn't interrupted.

The earliest warning sign is simply not eating. A rabbit that ignores its hay for 4-6 hours, especially combined with reduced or absent fecal output, is showing signs that demand veterinary attention the same day -- not the next morning, not after the weekend.

What Triggers Stasis -- and the Hay Connection

GI stasis is not a disease but a symptom -- it can be triggered by pain (dental disease, urinary problems, musculoskeletal injury), stress (loud noises, changes in environment, predator presence), dehydration, hairballs (trichobezoars), or most commonly, insufficient dietary fiber. A diet high in pellets and low in hay produces a gut microbiome and motility pattern that is predisposed to stasis. A diet of unlimited timothy hay produces a gut that moves consistently and handles minor disruptions without shutting down.

Timothy hay should make up 80-90% of a rabbit's diet by volume and should always be available. The fiber content drives cecotrope production, healthy cecal bacteria, and the continuous peristaltic contractions that keep the gut moving. Pellets are a supplement, not a staple. Rabbits fed primarily pellets are significantly more likely to develop stasis, dental disease, and obesity.

Recognizing Stasis Before It Becomes a Crisis

Know your rabbit's normal baseline: how much it eats, how many fecal pellets it produces (healthy rabbits produce dozens daily), what its normal activity level looks like. Stasis announces itself as deviation from normal -- less food eaten, smaller or fewer pellets, reduced activity, hiding more than usual, and eventually a characteristic hunched posture with abdomen pressed to the floor and teeth grinding (bruxism) that indicates pain.

Feel the abdomen gently: normal rabbit guts feel soft with some gurgling if you press an ear against the side. An abdomen that is bloated, tight, or completely silent is an emergency. Bloated abdomen plus no gut sounds plus hunched posture = rush to an emergency exotic vet, not a morning appointment.

What Treatment Actually Looks Like

The treatment protocol for GI stasis in rabbits combines several approaches simultaneously. Fluid therapy (subcutaneous or IV) addresses dehydration and helps rehydrate gut contents. Pain management -- meloxicam (an NSAID at 0.5-1 mg/kg) or buprenorphine for severe pain -- is critical because pain itself perpetuates the stasis cycle. Gut motility drugs encourage peristalsis to restart. Syringe feeding of critical care formula (such as Oxbow Critical Care) maintains nutrition and provides fiber that continues to stimulate gut movement.

Never give a rabbit pain medication or simethicone (Gas-X) without a diagnosis from a vet -- simethicone for gas is sometimes recommended but requires confirming that the problem is gas rather than an intestinal blockage, which requires different treatment entirely. Do not try to massage the abdomen vigorously at home -- this can rupture a gas-distended cecum.
