My big boy who we adopted was neutered after we got him. Well we have two unspayed females one who is in heat right now. Bauer(the male) mounted Aurora(the female) last night. She started screaming and I noticed he was in her. Can a neutered male even (for lack of a better term) get it up? We did get him when he was about 3 years old and he I'm sure when he was a stray got plenty of practice. Now I'm paraniod that was are going to have puppies!!
