I feel weird asking about this but here we go. Pepperoni and Monster were both neutered at about 6 months old. They are now about 2 years old, about a month apart in age. Once the other day and again this morning I caught Pepperoni (boy) on top of Monster (boy) pretty much going to town (pardon the expression). I noticed this behavior often back soon before they were both neutered. But until recently, this behavior seemed to stop. Although Monster is a large Siamese cat, I am concerned that Pepperoni (average shorthair) might hurt him. And I'm also concerned about Pepperoni because that just doesn't seem normal. I have had many cats, but don't remember ever really having a problem like this before. Is it common for a neutered male cat to have this kind of behavior and urges? And does this mean Pepperoni is a homosexual cat?
