GI Stasis in Rabbits

What Is GI Stasis?

GI stasis occurs when the digestive system slows dramatically or stops completely. Unlike humans, rabbits need a constant flow of food through their gut. When they stop eating — for any reason — the digestive system can essentially "shut down."

This allows harmful bacteria to multiply, producing gas and toxins that cause:

• Severe bloating and pain
• Dehydration
• Organ failure
• Death (if untreated)

What Actually Happens

Unlike what many people think, GI stasis is not caused by fur balls. The truth is the reverse: fur balls are the result of reduced gut motility, not the cause.

When a rabbit's digestive system slows down, water gets pulled from the intestines. The stomach contents dehydrate and harden, combining with undigested food and any ingested hair to form an impaction. The slowdown also disrupts the delicate bacterial balance in the caecum — allowing harmful bacteria like Clostridia species to proliferate. These bacteria produce gas and toxins that cause bloating, pain, and further damage.

Early Signs to Watch For

• Decreased appetite — Refusing hay, pellets, or treats
• Reduced droppings — Poops become smaller, drier, or stop entirely
• Lethargy — Less active, sitting hunched
• Teeth grinding — Sign of pain or discomfort
• Hunched posture — Trying to relieve belly pain

Advanced Signs (Seek Emergency Care!)

• No eating or drinking for 12+ hours
• No droppings for 12+ hours
• Visible bloating or hard stomach
• Refusing to move
• Weakness or collapse
• Labored breathing

What Causes GI Stasis?

GI stasis is typically triggered by an underlying problem:

• Diet issues — Not enough fiber, too many pellets, not enough water
• Stress — Changes, loud noises, new pets
• Pain — Dental problems, GI obstruction, bloat
• Dehydration — From illness or insufficient water
• Illness — Infections, parasites, or other diseases

How a Vet Diagnoses It

A veterinarian will distinguish between two conditions that look similar but require very different treatment. This distinction is critical — giving motility drugs to a rabbit with a physical obstruction can rupture the stomach and kill the rabbit. A vet will always take X-rays before administering motility medications.

Your vet will also ask about diet, living conditions, recent life changes, and when the rabbit last passed normal droppings. A dental exam is essential because dental pain is one of the most common triggers of stasis — look for drooling, damp dewlaps, and matted fur around the mouth.

Treatment

Veterinary treatment may include:

• Fluid therapy — IV fluids at 100 ml/kg/day in severe cases; oral fluids for mild cases
• Pain medication — Doses for rabbits are very different from dogs and cats; never use OTC pain meds without vet guidance
• Motility drugs — Only after X-rays confirm no physical obstruction
• Assisted feeding — Critical Care, Recovery, or Emeraid syringe-fed formula
• Treating the underlying cause — Dental work, infection, stress reduction

Gas reduction drugs (similar to infant colic remedies) are sometimes recommended. Their effectiveness in rabbits is uncertain — in humans they work by letting gas collect into a single bubble that can be "burped" out, but rabbits cannot burp. They are not absorbed by the body and are unlikely to cause harm.

Home Care While Getting to the Vet

If you cannot reach a vet immediately, there are steps you can take while arranging care:

• Keep the rabbit warm — a rabbit in shock loses body heat rapidly. Wrap in a towel and hold against your body.
• Encourage eating — offer their favorite hay, fresh herbs (cilantro, parsley), or wet greens. Even a few bites help.
• Subcutaneous fluids — only if your vet has taught you and provided supplies
• Gentle belly massage — clockwise, for 2-3 minutes at a time, can help release trapped gas
• Movement — gentle walking or hopping can stimulate gut motility

Recovery: The 48 Hours After Treatment

After veterinary treatment, monitoring continues at home:

• Appetite should return within 12-24 hours of treatment starting. If your rabbit isn't eating by 24 hours, call the vet.
• Watch the droppings — this is the most reliable sign of recovery. 100-300 poops per day is normal. Look for pellets to return to normal size and quantity.
• Continue pain management as prescribed. Rabbit pain medication dosing is very different from dogs and cats.
• Assisted feeding continues until the rabbit is eating independently. Follow your vet's instructions for amount and frequency.
• Limit exercise for a few days — the gut needs time to fully recover.
• Follow-up — your vet may want to recheck in 48-72 hours, especially if the case was severe.

Prevention

• Unlimited timothy hay — Available 24/7. Fiber is the single most important factor in preventing GI stasis.
• Limited pellets — 1/4 cup per 5 lbs body weight
• Fresh water — Always available, changed daily
• Minimize stress — Stable routine, safe environment, avoid sudden changes
• Daily monitoring — Watch appetite and droppings every day
• Regular vet visits — Catch problems early, including dental checks
• Grooming — Reduces hair ingestion, especially in long-haired breeds

When the Prognosis Is Poor

GI stasis that goes untreated for more than 24-48 hours, or cases involving complete intestinal obstruction, may be beyond saving. Rabbits hide illness so well that by the time stasis becomes obvious, it may already be life-threatening.
