Male cats if they are neutered make WONDERFUL pets and are no more mean than female cats. When females are involved, intact males can be pretty nasty as they are focused on the female. As a breeder, I personally think my neutered boys are sweeter than the girls. They love attention and people. Girls are more focused on themselves.
Please let me know if I can help further.
