If they are caught early, often medical therapy alone is very successful. Unfortunately, the prognosis for this procedure is only fair. So, if your rabbit goes off its feed, produces less stool than normal, has abnormal amounts of hair in its stool, or feels like it has a wadded sock in its abdomen, your rabbit needs to see its veterinarian immediately. Please note that rabbits produce two types of stools. The day stools are the dark brown firm pellets that you clean up every day.
Rabbits also have a mucus covered night stool that is generally eaten as they are produced.
These night stools are an important source of protein and vitamins. Although night stools are rarely seen, a few may drop to the cage floor. They should not be mistaken for diarrhea. Low fiber in the diet also predisposes rabbits to an almost always fatal diarrhea called proliferative enteritis. A low level of fiber changes the acidity of the intestines.
