Urinary sphincter mechanism incontinence is the most common cause of urinary incontinence in dogs and cats. Artificial urethral sphincter implantation is a surgical procedure that has been performed in humans for decades, and has more recently been used in dogs to correct urinary incontinence. While there is much research on dogs, there is very little literature on the procedure and success rate in cats. This case report is focused a cat with urethral sphincter mechanism incontinence that underwent artificial sphincter implantation. The patient was 90% continent at the 6 week recheck, and 100% continent 6.5 months post-operatively with one minimally invasive sphincter adjustment. The artificial urethral sphincter implantation had an excellent short term outcome in this patient, but additional studies are needed to look at long term outcomes in both cats and dogs to fully assess the benefits of this procedure over other treatment options.
