Cat Perineal Urethrostomy Welfare

Perineal urethrostomy is a surgical procedure for male cats with recurrent urethral obstruction, with welfare implications pre and post-surgery.

Key Facts

PU surgery widens the urethra to reduce recurrence of obstruction
Male cats with two or more obstructions are candidates for PU surgery
Post-operative care includes pain management and litter tray management
Most cats have excellent quality of life post-PU surgery
The decision for surgery involves balancing chronic obstruction risk against surgical risk

Welfare Considerations

Recurrent urethral obstruction causes repeated acute suffering through inability to urinate. PU surgery effectively prevents recurrence in most cases, trading one-time surgical recovery for freedom from repeated crises. When cats have experienced multiple obstructions, the welfare case for PU surgery is strong. Post-operative pain management is essential.

What You Can Do

Discuss PU surgery with your vet after a second urethral obstruction in a male cat
Ensure appropriate pain management during recovery from PU surgery
Monitor post-PU cats for urinary tract infection which is more common after surgery
