Hi everyone. So I have a shared housing situation and I just got a new roommate who has a possibly not neutered 4 year old male cat. I've been living here for quite a while and my cat is the resident kitty. My soon to be 3 neutered male cat is very skiddish. So it's hard to say whether he actually owns everything in my house or what. Anyways, so I tried to introduce the two cats again tonight, but the not neutered cat kept growling at my cat. I used the door method with a slight crack so they could see each other. Was this wrong? It's the second day here and the other cat gets more free run because he is an outdoor cat and mine is strictly indoor. I need so help please!
