Hi, I have a question about neutering my cat. He is getting it done today but I am worried about when he gets home because I have another cat that is very bitchy about cats she doesn't know (she is spayed BTW). In fact my cousins cat came to live with us for a good 6 months and she would stalked and growled at him none stop (luck for us and him he was an inside/outside cat and most of the time he was here it was nice out). Anyway I heard that after a cat is neutered there smell changes. Will my other cat is recognize him when he gets home?
