CLINICAL PRESENTATION AND INVESTIGATIONS: An 11-week-old female domestic shorthair kitten presented with a history of constipation since weaning. Abdominal distension was noted on physical examination and abdominal radiographs revealed a large volume of faeces in the descending and transverse colon. Colonoscopy was unremarkable and euthanasia was performed at the owners' request.
Diagnosis: The histological diagnosis of large intestinal hypoganglionosis was made post mortem.
Significance: This appears to be the first reported case of congenital hypoganglionosis in a kitten with histopathological confirmation of the diagnosis. It may potentially be a more common cause of constipation in kittens and young cats than has previously been suspected.
