Rabbit GI Stasis: Emergency Signs, Treatment & Prevention

GI stasis is the most common and dangerous emergency in pet rabbits. The gastrointestinal tract slows down or stops completely. Without treatment, a rabbit can die within 24-48 hours. Every rabbit owner must know the signs.

What Is GI Stasis?

A rabbit's digestive system must keep moving continuously. When it slows or stops, gas builds up, toxins accumulate, and the rabbit stops eating — which makes it worse. It's a vicious cycle. Unlike dogs and cats, rabbits cannot vomit. Their entire system is designed for one-way, continuous movement of food and fiber.

The #1 Sign: Not Eating

A rabbit that hasn't eaten in 8-12 hours is an emergency. Not "wait until morning." Not "see if they feel better." GI stasis becomes harder to treat — and more expensive — with every hour of delay. Check for: refusing even favorite treats, no fecal pellets or small/misshapen pellets (poop is the BEST indicator of gut health), hunched posture pressing belly to the floor (pain response), loud teeth grinding (bruxism — sign of significant pain), and abdominal distension (swollen, firm belly).

Common Causes

Inadequate fiber intake (the most common cause — not enough hay), dehydration, stress (loud noises, new pet, travel, temperature extremes), dental disease causing pain when chewing (extremely common in rabbits), hairball obstruction from ingested fur during shedding season, underlying illness (infection, organ disease), and lack of exercise.

At-Home Care While Preparing to Go to the Vet

Syringe feed Critical Care (Oxbow or Emeraid) — food in = food out. This restarts gut motility. Target: 10-20 mL per feeding, every 4-6 hours. Simethicone (infant gas drops) — 20-40 mg every 6-8 hours. Safe to give at home and helps relieve gas pain. Keep the rabbit warm — GI stasis causes hypothermia. Gently massage the belly if the rabbit tolerates it. Encourage movement — gentle exercise stimulates gut motility.

Never force-feed a rabbit who may have a complete obstruction. If you're unsure whether it's stasis or obstruction, go to the vet. And NEVER use yogurt or probiotics containing dairy — rabbits are herbivores and dairy makes things worse.

At the Vet

Subcutaneous or IV fluids (rehydrating GI contents is the most important first step), pain management (meloxicam +/- buprenorphine — rabbits in pain won't eat), prokinetics (metoclopramide, cisapride) to stimulate gut motility, syringe feeding with Critical Care, abdominal radiographs to assess gas patterns and rule out obstruction, and dental examination (dental disease is a common underlying trigger).

Prevention

Unlimited timothy or orchard hay — 80% of diet, always available. Limited pellets (1/4 cup per 5 lbs body weight). Fresh leafy greens daily. Constant access to fresh water (bowl preferred over bottle). Daily exercise — 4+ hours out of cage. Regular dental checks every 6-12 months. Reduce stress — consistent routine, hiding spots, quiet environment.

What Every Rabbit Owner Should Have

Critical Care (Oxbow or Emeraid Herbivore) — buy it BEFORE you need it. 1 mL syringes for feeding. Simethicone infant gas drops. Your exotic vet's phone number and the nearest 24/7 emergency vet that sees rabbits.

GI stasis is terrifying but survivable with fast action. The key: know the signs, have supplies ready, and don't wait.
