My husband's friend's parents wanted him to get rid of his 9-year-old cat & he asked us if we would take him. We said we would see how our current cat, Mama, reacted to him before we decided to keep him or not. He dropped the cat off yesterday and we let him out while Mama was in the room so she would not attack him (she does NOT like other animals). He immediately ran behind my desk to the window. We decided to leave him alone for an hour to see if he would come out. He did not. We finally let Mama out and she was pretty good.. she was sniffing around because she could smell him and when she finally found him, they had a VERY quick spat (in which I grabbed Mama and put her in the room). We left him alone all night with Mama in the room.. he went in the fireplace and stayed there all night (don't worry, it is clean and we haven't used it in the two years we've been here lol). We eventually got him out this morning and every time we would go near him he would hiss and growl at us. Even when I looked at him, he would growl at me. I have never had a cat do that. He won't let me pet him or even get close to him. It is almost like he's been abused. The friend's family doesn't seem like the type that would abuse animals (they are very rich and well-to-do) but you never know. He finally came out about 2 hours ago when we put Mama back in the room (she has pretty much been ignoring him) but he just went to the kitchen and jumped up on the fridge and hid in the very back. I went to pet him and he hissed and growled at me some more. He has been with us for 1 1/2 days now. Any advice? Is this normal? What should I do? He said he would take the cat back if it doesn't work out.
