GI Stasis in Rabbits: A Silent and Deadly Welfare Emergency

Gastrointestinal stasis — the slowing or stopping of gut movement — is the most common life-threatening emergency in pet rabbits. Understanding its causes and prevention is fundamental to rabbit welfare.

Key Facts

GI stasis occurs when normal gut motility decreases, allowing gas to accumulate and bacteria to overgrow
Common triggers include inadequate hay intake, stress, pain from other conditions, and dehydration
Hay should constitute approximately 80% of a rabbit's diet by volume to maintain gut motility
Signs include reduced or absent faecal pellets, hunched posture, tooth grinding, and refusal to eat
GI stasis can become fatal within 24–48 hours if untreated due to gas pain and systemic collapse
Treatment includes gut motility drugs, fluid therapy, pain relief, and hand-feeding of critical care formula
Rabbits are obligate herbivores whose digestive systems require constant movement to function
Muesli-style rabbit feeds (which allow selective feeding) are associated with dental disease that predisposes to stasis

Welfare Considerations

GI stasis is a welfare emergency that causes intense pain — the gas accumulation associated with gut slowdown is acutely uncomfortable, comparable to severe colic. Rabbits hide pain instinctively, so by the time owners notice signs, the condition is often advanced. The primary prevention is dietary: unlimited hay is the single most important factor in maintaining healthy gut motility, yet many rabbit owners provide inadequate hay and instead offer muesli mixes or excessive pellets that displace hay intake. Stress is a significant secondary trigger — rabbits kept in inadequate housing, with inappropriate companionship, or in environments with predator presence (including cats and dogs) experience chronic stress that predisposes them to stasis. Environmental enrichment, appropriate social bonding, stress-free handling, and rapid response to early warning signs are all components of responsible rabbit welfare. Rabbits are widely underestimated as companions with complex needs equal to or exceeding those of cats or dogs.

What You Can Do

Provide unlimited hay (preferably timothy or meadow hay) as the foundation of your rabbit's diet
Eliminate muesli-style feeds in favour of high-quality pellets in small amounts plus hay and fresh greens
Learn the early warning signs of GI stasis — reduced droppings and reduced appetite are red flags
Seek emergency veterinary care within hours, not days, if you suspect GI stasis
Minimise sources of stress in your rabbit's environment — housing, social bonds, and noise levels all matter
