GASTROINTESTINAL STASIS IN RABBITS
Amy B. Worell, DVM, ABVP-Avian
Gastrointestinal stasis (GI Stasis) is one of the more common but preventable presentations that I treat rabbits for. GI stasis occurs when the speed of the material that moves through the gastrointestinal tact is altered; such that the stomach and cecum empty slower than normal or completely stop. This often will result in a decreased appetite for food items and a cessation in water drinking. The body then compensates for these changes by extracting water from the stomach and intestinal tract such that the contents of the entire GI tract become further dehydrated and impacted. The pet is then unable to pass the ingesta in the stomach, apparently feels full, uncomfortable and often is mildly to extremely painful in the cranial or front part of the abdomen, where the stomach is located. GI stasis can be a life threatening occurrence and immediate veterinary care should be sought.
Clinical signs of GI stasis vary but may include some or all of the following:
- Lethargy, not wanting to move or eat. NOTE: The nose is usually not wiggling.
- Fecal droppings may not be present or may be present in decreased numbers.
- Fecal droppings may be small or stuck together with hair.
- Gurgling sounds may be heard from the abdomen.
- Sounds of grinding teeth. (Usually suggests pain)
- Bloated or distended abdomen.
Causes of GI Stasis often involve one or more of the following predisposing factors:
- Inappropriate diet such that the fiber level is too low.
- Inappropriate consumption of items such as carpet or blankets.
- Lack of proper exercise.
- Stress such as changes in environment or loss of a companion.
Prevention of GI Stasis revolves around feeding your rabbit a proper diet. Alfalfa products (hay and pellets) are NOT recommended as they are too high in calcium and can result in other medical issues with rabbits. Diets that are timothy hay based (oat hay is ok also but many rabbits will not eat it) are the usual recommendation. This involves both the pellets that the pet eats and the daily hay that should be offered.
Specifically, we recommend a diet consisting of:
- Fiber levels between 18-24%.
- Controlled levels of carbohydrates and protein.
- Fresh leafy greens such as mint, basil, dill, cilantro, parsley, or lettuce. This should be fed at the rate of ½ cup per 5 pounds of body weight daily.
- Other veggies or fruits in limited quantities.
- Unlimited access to grass hay. Timothy, oat, meadow, rye or barley are all ok.
- Timothy based pellets. Should be offered either free choice or at the rate of ¼ cup per 4 pounds of body weight daily.
- Free choice fresh water at all times.
If at any time you feel that your rabbit is showing clinical signs that could be compatible with GI stasis, please make an appointment immediately, not tomorrow, for an examination with a veterinarian experienced in care of rabbits.
