Rabbit GI Stasis: Recognition, Prevention, and Emergency Response

Gastrointestinal stasis is a life-threatening emergency in rabbits that kills within 24-48 hours if untreated. Recognition and rapid response are essential for rabbit welfare.

Key Facts

GI stasis occurs when the rabbit's digestive system slows or stops, allowing gas to accumulate and gut bacteria to overproduce
The rabbit digestive system requires constant motion - even short periods of reduced movement can become stasis
Primary causes include low-fiber diet, stress, pain from other conditions, dehydration, or hairballs
Signs include reduced or absent fecal pellets, reduced or absent appetite, hunched posture, and tooth grinding
GI stasis is often misidentified as constipation - incorrect home treatment delays life-saving veterinary care
Mortality can occur within 24-48 hours without treatment - this is always a veterinary emergency

Welfare Considerations

GI stasis causes severe abdominal pain from gas accumulation and rapidly becomes fatal as the rabbit's condition deteriorates. The welfare urgency is extreme - rabbits that appear unwell in the evening are often critical or dead by morning if untreated. Because rabbits hide illness, mild cases are often missed until the rabbit is already in significant distress. Prevention is the welfare priority: high-fiber hay-based diet, stress reduction, regular exercise, and prompt treatment of any condition that causes pain or stress that could trigger secondary stasis. Rabbit owners must recognize that any change in eating or defecation habits in a rabbit warrants immediate veterinary assessment.

What You Can Do

Feed unlimited timothy hay as the primary diet (70-80% of food intake) to maintain gut motility
Never allow more than 12 hours without eating or defecating before seeking veterinary care
Know the location and hours of your nearest rabbit-experienced emergency veterinary clinic before you need it
Recognize early warning signs: reduced pellet production, food refusal, hunched posture, or visible bloating
Do not wait and see with GI stasis - contact a rabbit-savvy vet immediately if you suspect it
Keep your rabbit's environment stress-free and ensure daily exercise to maintain gut motility
