A three year old, non-descript female cat, neutered seven months back was presented to the University Veterinary Hospital, Kokkalai with history of purulent vaginal discharge for the last four months and repeated oestrous signs. No palpable abnormalities could be detected on physical examination of abdomen. Abdominal ultrasonography revealed an anechoic sac located posterior to the bladder. Vaginal smear examination revealed presence of numerous degenerated neutrophils. The case was presumptively diagnosed as stump pyometra. Two ovaries along with distended remnant uterine horns and uterine stump were removed by laparotomy. Post operatively the animal was treated with antibiotics, fluids and analgesics for a week. The animal had an uneventful recovery.
