title: Spontaneous pneumoperitoneum in two cats.
abstract: Spontaneous pneumoperitoneum is an infrequently observed presentation in cats. This report details two cases of pneumoperitoneum in the cat. The first case was suspected to have been caused by a gastric perforation secondary to gastric lymphoma. The second case was caused by a perforated gastric ulcer in a cat that had been recently treated with corticosteroids and a non-steroidal anti-inflammatory drug.
