Depending on clinical and ultrasonographic findings, unilateral uterine prolapse was diagnosed in both of the cats. Uterine prolapse was occured just after the last delivery in Case 1, and was occured 3 days after parturition in Case 2. Ovariohysterectomy was performed following manual reduction and intra-abdominal retraction of the prolapsed tissue in both cats.
