I know it’s a no brainer for most people, but I am seriously concerned. I had a cat who I loved dearly and one month after his neutering operation he developed urethral obstruction and two months later he died despite the vet’s best effort. I couldn’t help but conclude that the operation had a hand in what happened somehow because before it he was perfectly healthy. I searched online and some websites say that the desexing operation narrows the urethra which makes it much easier for it to become obstructed. I recently adopted two adult male cats (ages 3 and 5 years old my old cat was 7 years old when he had the operation) and I am kinda terrified of getting them neutered. Would the operation really increase their chances of getting an obstruction?
