An approximately four-year-old male castrated guinea pig (Cavia porcellus) was presented for painful defecation with a 24 hour history of hyporexia, intermittent episodes of rolling behavior, and decreased urination. Upon presentation the patient was quiet, alert, and responsive, and mildly hypothermic. Abdominal palpation revealed an approximately one inch long oblong mass effect within the caudal abdomen. Abdominal radiographs were performed and revealed gastric dilation without volvulus and a peritoneal mass effect. The patient was euthanized following gastric reflux of brown malodorous fluid from his nares and oral cavity. A necropsy was performed and confirmed a jejuno-jejunal intussusception causing mechanical gastrointestinal ileus, and gastric dilatation without volvulus. To the authorsÂ’ knowledge this is the first report of a jejuno-jejunal intussusception in a guinea pig.
