Why is my male cat's neuter area swollen again after surgery?

Updated On September 23rd, 2025

My male cat was neutered about two weeks ago. We have already had to take him back in for swollen testicles. They said it was a blood clot. A few days later, the area is swollen again! What is going on?

He may have a bleeding disorder and the scrotum may be full of blood again. It may also be infected or inflamed. Do not let your cat lick the scrotum as it irritates it and may introduce infection. If the swelling is cool, you can just observe it and over time it should shrink again and the body will have reabsorbed the blood. If the swelling is hot or painful or red, then you will need to take your cat back to the vet for a recheck.
