Gastrointestinal (GI) stasis is one of the most common and dangerous health conditions affecting pet rabbits. It occurs when the normal movement of the digestive system slows down or stops entirely, allowing harmful bacteria to build up in the gut. Left untreated, GI stasis can be fatal within 24-48 hours. Every rabbit owner should know how to spot the warning signs and act quickly.
What Is GI Stasis?
GI stasis, also called gastrointestinal hypomotility, happens when a rabbit's digestive tract slows or stops processing food. Rabbits rely on a constant flow of fiber through their system to maintain healthy gut bacteria and keep things moving. When that process breaks down, gas builds up, bacteria multiply, and toxins can enter the bloodstream.
GI stasis is almost always secondary to an underlying issue β it's the rabbit's digestive system reacting to something else going wrong in the body.
Common Causes
- Poor diet β Not enough hay or fiber, too many pellets or sugary treats
- Dehydration β Insufficient water intake dries out gut contents
- Stress β Changes in environment, loss of a bonded partner, loud noises
- Pain β Dental problems, urinary infections, arthritis, or other hidden pain sources
- Lack of exercise β Sedentary rabbits have sluggish digestive systems
- Ingesting fur β Especially during heavy shedding seasons
- Sudden diet changes β Rapid shifts in food can disrupt gut flora
Symptoms to Watch For
Recognizing GI stasis early is critical. Watch for these signs:
- Decreased appetite or refusing food entirely (especially treats)
- Reduced or no fecal pellets, or very small/dry droppings
- Bloated or tight-feeling belly
- Teeth grinding (a sign of pain)
- Hunched posture or reluctance to move
- Cold ears (indicating low body temperature)
- Lethargy or hiding more than usual
Important: If your rabbit hasn't eaten or produced droppings for more than 4 hours, treat it as an emergency.
What to Do If You Suspect GI Stasis
At Home (First Aid)
- Administer simethicone (baby gas drops) β Available at any pharmacy, these help break up gas bubbles. Give 1-2 mL every hour for the first 3 hours.
- Syringe water β Gently offer water via syringe to keep your rabbit hydrated.
- Gentle belly massage β Carefully massage your rabbit's abdomen in slow, circular motions to help stimulate gut movement.
- Encourage movement β Let your rabbit hop around in a safe space. Exercise naturally stimulates the digestive system.
- Offer fresh herbs β Cilantro, parsley, or dill may tempt a rabbit that has lost its appetite.
Veterinary Treatment
If home care doesn't produce improvement within a few hours, get to a rabbit-savvy vet immediately. Veterinary treatment typically includes:
- Fluid therapy β Subcutaneous or IV fluids to rehydrate your rabbit and the gut contents
- Pain medication β Meloxicam (Metacam) is commonly prescribed to address abdominal discomfort
- Motility drugs β Medications like metoclopramide (Reglan) to help restart gut movement
- Critical Care feeding β Syringe feeding a high-fiber recovery formula like Oxbow Critical Care
- X-rays β To check for blockages or severe gas buildup
Prevention Tips
The best treatment for GI stasis is preventing it from happening in the first place:
- Unlimited hay β Timothy hay (or orchard grass) should make up 80% or more of your rabbit's diet. Hay keeps the gut moving and wears down teeth.
- Fresh water always available β Some rabbits prefer bowls over bottles. Make sure water is clean and accessible.
- Daily leafy greens β Offer 2-4 cups of fresh greens per 5 lbs of body weight. Greens add moisture and nutrients.
- Limited pellets β Use high-fiber pellets (22%+ crude fiber) sparingly, about 1/4 cup per 5 lbs of body weight.
- Regular exercise β Give your bunny several hours of free-roaming time daily in a bunny-proofed space.
- Groom during shedding β Regular brushing reduces fur ingestion.
- Minimize stress β Keep a consistent routine and provide hiding spots for comfort.
- Regular vet checkups β Annual exams with a rabbit-savvy vet can catch problems early.
Keep an Emergency Kit Ready
Every rabbit owner should have these supplies on hand:
- Simethicone (infant gas drops)
- Syringes (for feeding and hydration)
- Oxbow Critical Care or equivalent recovery food
- Your rabbit-savvy vet's emergency contact number
GI stasis is scary, but with quick action and proper prevention, most rabbits recover fully. Stay observant, keep that hay rack full, and don't hesitate to call your vet if something seems off. Your bunny is counting on you.
