My cat is spayed and has been sinse he was 5 months old. He has never had this problem. I live in a small studio apartment and a big outside shared garden where there are many stray cats!! I have recently found a small 3 week old kitten outside and brought him in the house for 3 days until i had found him a home! Sinse my cat has started spraying? i know this is probably the reason but how do i stop him?
