This study details a case of priapism in a 3-year-old, male, crossbreed cat weighing 5,4 kg treated successfully with surgery. The cat was brought to the Afyon Kocatepe University Veterinary Health Application and Research Centre for general examination and castration. Clinical examination revealed a fully erect and hard/solid penis. Serum biochemistry, complete blood count, and testosterone results of the animal were within the reference ranges except for urea. When the conservative treatment was unsuccessful, it was decided to perform a perineal urethrostomy operation. Postoperative examination on day 10 revealed healing and comfortable urination; thus, the stitches and urinary catheter were removed. In conclusion, this report of successful treatment of priapism in a cat through perineal urethrostomy can contribute to veterinary literature.
