🚨 THIS IS A MEDICAL EMERGENCY
Seek immediate veterinary attention. Do not wait or attempt home treatment. Every minute counts.
GI Stasis in Rabbits
The most common and dangerous digestive emergency in rabbits. The gastrointestinal tract slows down or stops completely, leading to painful gas buildup, toxin accumulation, and death if untreated.

When to Act
🚨 Immediate Emergency Care
Symptoms & Signs
Not eating or drinking
Complete refusal of food including favorite treats — a rabbit emergency within 12-24 hours.
No or reduced fecal pellets
Small, misshapen, or absent droppings. Poop is the best indicator of rabbit gut health.
Lethargy and hunched posture
Rabbit sits hunched in a corner, reluctant to move. May press belly to the floor (pain response).
Abdominal distension
Swollen, firm belly that may sound hollow when tapped (gas) or feel doughy (impacted).
Teeth grinding (bruxism)
Loud grinding of teeth — a sign of significant pain in rabbits.
Behavioral Changes to Watch For
Pets can't tell us what's wrong. These behavioral changes are often the first clues that something is wrong.
🐾 Withdrawal and hiding
Rabbit hides and refuses interaction — a prey animal's response to feeling vulnerable.
What You May Notice:
Your normally social rabbit stays in a corner with their back to you, refusing treats.
🐾 Pressing belly to floor
Rabbit lies flat with belly pressed against the cool floor to relieve abdominal pain.
What You May Notice:
Your rabbit stretches out in an unusual posture and seems uncomfortable.
Causes & Risk Factors
Causes
- •Inadequate fiber intake (too many pellets, not enough hay)
- •Dehydration
- •Stress (loud noises, new pet, travel, temperature extremes)
- •Dental disease causing pain when chewing (common in rabbits)
- •Hairball obstruction from ingested fur during shedding
- •Underlying illness (infection, organ disease)
- •Lack of exercise
Risk Factors
- ⚠Diet low in hay/high in pellets and treats
- ⚠Obesity and sedentary lifestyle
- ⚠Chronic dental problems
- ⚠Shedding season (heavy fur ingestion)
- ⚠Recent stressful events
- ⚠Older rabbits
How It's Diagnosed
- 1Physical examination — abdominal palpation, auscultation (absent gut sounds)
- 2History of reduced appetite and fecal output
- 3Abdominal radiographs to assess gas patterns, obstruction, or masses
- 4Blood work — may show dehydration, liver enzyme changes
- 5Dental examination to rule out dental disease as underlying cause
Treatment Options
Fluid Therapy
Rehydrating the GI contents is the most important first step.
Steps
- 1.Subcutaneous or IV fluids (Lactated Ringer's)
- 2.Warm fluids to prevent hypothermia
- 3.Fluid bolus followed by maintenance rate
Expected Outcome
Rehydrated GI contents can begin moving again within hours.
Precautions
- !IV access is difficult in rabbits — SC fluids are more common
Syringe Feeding (Critical Care)
Nutritional support to restart gut motility — food in = food out.
Steps
- 1.Oxbow Critical Care or Emeraid Herbivore — syringe feed every 4-6 hours
- 2.Mix to a slurry consistency
- 3.Target: 50-100 mL/kg/day divided into multiple feedings
- 4.Continue until rabbit is eating hay and producing normal droppings voluntarily
Expected Outcome
Restarting gut motility within 12-24 hours with consistent feeding.
Precautions
- !Never force-feed a rabbit with a complete obstruction — may cause rupture
Pain Management and Prokinetics
Pain control is essential — rabbits in pain will not eat.
Steps
- 1.Meloxicam (Metacam) — NSAID for pain and inflammation
- 2.Simethicone (baby gas drops) — for gas relief
- 3.Prokinetics (metoclopramide, cisapride) — stimulate gut motility
- 4.Buprenorphine for severe pain
Expected Outcome
Pain relief allows the rabbit to resume eating within hours.
Precautions
- !Prokinetics are contraindicated if a physical obstruction is present
Common Medications Used
| Medication | Usage | Important Notes |
|---|---|---|
| Meloxicam (Metacam) | NSAID for pain and inflammation in rabbits | Well-tolerated in rabbits. Oral suspension given once daily. |
| Simethicone | Anti-gas medication to relieve bloat | OTC infant gas drops. Safe to administer at home while preparing to see a vet. |
Prevention
- ✓Unlimited timothy/orchard hay (80% of diet)
- ✓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
When to See a Veterinarian
- 🚨Rabbit hasn't eaten in 8-12 hours — treat as urgent
- 🚨No fecal pellets in 12+ hours
- 🚨Lethargy + hunched posture
- 🚨Loud teeth grinding
Frequently Asked Questions
I noticed my rabbit isn't eating — can I wait until tomorrow?
What should I have in my rabbit emergency kit?
Prognosis
Excellent with prompt treatment (within 12-24 hours of first signs). Delayed treatment beyond 24-48 hours significantly worsens prognosis. Most rabbits recover fully with appropriate supportive care.

Related Conditions
Dental Malocclusion in Rabbits
Rabbits' teeth grow continuously throughout their lives. When teeth don't align properly (malocclusion), they overgrow, causing severe pain, inability to eat, and secondary infections.
moderateHead Tilt (Wry Neck / Vestibular Disease) in Rabbits
A neurological condition where the rabbit holds its head twisted to one side, often with loss of balance. Most commonly caused by E. cuniculi infection or inner ear infection. Treatable if caught early.
severeFlystrike (Myiasis) in Rabbits
A devastating condition where flies lay eggs on a rabbit's skin, and the hatching maggots feed on the rabbit's flesh. Occurs rapidly in warm weather. A true emergency that can be fatal within 24-48 hours.
severeCanine Parvovirus (Parvo)
A highly contagious and life-threatening viral disease in dogs, especially puppies. Causes severe vomiting and bloody diarrhea. Immediate veterinary care is critical.
