Objective: A secondary ectopic pregnancy is defined as continuing development of a fetus in the abdominal cavity after rupture of the uterine wall, which may be associated with a history of trauma. Methods: A cat was referred to the veterinary teaching hospital of the University of Tehran with history of anorexia and vaginal bleeding. In clinical examination some masses werepalpated in abdominal cavity so the patient wasreferred to radiology and sonography for definite diagnoses. In ultrasonography examination three dead fetuses were detectedoutside the uterus. In US it so appeared that gestational sacs did not cover the fetuses and there was a rupture in cranial part of right uterine horn that made the case highly suspected to ectopic pregnancy caused by trauma. Results: Therefore the cat was prepared for aseptic surgery and anesthetized with isofulorane. After incision of the lineaalba three fetuses were seen outside the uterus that wereattached to abdominal wall (left and right wall) and mesentery. There was no sign ofgestational sac to cover the fetuses. The three fetuses were bluntly dissected from the attachments and all conspicuous vessels were ligated and the fetuses were removed. Ovariohysterectomy was also performed to prevent recurrence. Recovery was uneventful.
