He has had recurrent problems of not being able to urinate. He keeps forming bladder stones that block his urethra so the wee can’t flow out, causing a large, painful, distended bladder requiring urgent medical attention. He has had all the correct management, but sometimes that is not enough, so surgery is needed.
Male cats have an S bend to their very narrow urethra, which is the most common place for a blockage.
Colin has opened out the S bend and widened the opening for urine to flow out so Ziggy should not have to suffer blocking again.
We wish him a swift recovery so he can wave goodbye to his bright blue collar!
