The best answer is gastrointestinal obstruction. Click here to learn more.
- Dental disease is the most common cause of anorexia in pet rabbits and a normal oral examination in the conscious rabbit cannot completely rule-out dental disease.
- Ileus is a common clinical problem that can be a primary or secondary disease. Click here for helpful advice on distinguishing non-obstructive gastrointestinal disease from obstructive disease in the rabbit.
- Mucoid enteropathy is a condition typically seen in juvenile (~14 week old) rabbits fed inadequate dietary fiber and excess concentrate, although disease is occasionally seen in adults. Mucoid enteropathy is characterized by the presence of copious mucus in the colon despite minimal inflammatory changes. The cecum may be impacted. Gastric dilatation occurs in the terminal stages. Rabbits often present with a history of anorexia and depression. Although diarrhea or soft stools can be present early, rabbits often pass thick, gelatinous mucus or mucoid fecal material in the later stages of disease. Evidence of abdominal pain is often also observed. On physical examination the patient is hypothermic, dehydrated, and the cecum palpates firm or solid on abdominal palpation. This condition is progressive and usually fatal. Treatment is the same as for gastrointestinal ileus (Meredith 2008).
