Rabbit GI Stasis: A Life-Threatening Emergency Requiring Prompt Action

Gastrointestinal stasis is one of the most common and dangerous emergencies in pet rabbits. Understanding how to recognize and respond to it is essential for rabbit welfare.

Key Facts

GI stasis occurs when the normal movement of the rabbit's digestive tract slows or stops, causing gas buildup, pain, and potentially fatal gut damage.
Rabbits have a unique digestive system that must keep moving — any interruption becomes rapidly life-threatening.
Common triggers include inadequate hay intake, stress, pain from other conditions, or sudden diet changes.
Signs include reduced or absent fecal pellets, hunched posture, tooth grinding, reluctance to move, and a distended, painful abdomen.
GI stasis can kill within 24-48 hours without treatment — it is a veterinary emergency.
Treatment includes IV/SC fluids, gut motility drugs (metoclopramide, cisapride), pain relief, and syringe-feeding critical care formula.
Prevention centers on unlimited hay access — hay provides the fiber that keeps gut motility normal in rabbits.

Welfare Considerations

GI stasis causes significant abdominal pain in rabbits — the gas buildup creates intense pressure and discomfort. Rabbits are unable to vomit, making gas expulsion impossible except through normal gut motility. A rabbit in stasis is suffering acutely. The welfare tragedy is that GI stasis is almost entirely preventable through appropriate diet — rabbits fed unlimited grass hay have the fiber intake needed for normal gut function. Many cases develop in rabbits fed primarily pellets and fresh vegetables without adequate hay. Owners who recognize GI stasis and seek emergency veterinary care within hours have a good chance of saving their rabbit; those who delay face a much worse prognosis. Regular monitoring of fecal pellet production is the most important early warning system.

What You Can Do

Provide unlimited grass hay (timothy, meadow, or orchard grass) as the majority of your rabbit's diet — this prevents most GI stasis.
Monitor your rabbit's fecal pellet production daily — reduced or absent pellets are an early warning sign of GI slowdown.
Seek emergency veterinary care immediately if your rabbit shows signs of GI stasis — do not wait to see if it resolves.
Ensure your rabbit always has access to fresh water — dehydration slows gut motility.
Minimize stress in your rabbit's environment — sudden changes, loud noises, and new animals can trigger GI stasis.
Ask your vet to demonstrate how to assess gut sounds with a stethoscope — absent gut sounds indicate stasis.
