How do I get my old cat to accept our new cat?
My old cat is a little over 2 years old. I have had her since she was a little baby. Her mom was eaten by a mountain lion so I helped bottle feed her ad then soon adopted her. She is super spoiled and it is hard for my boyfriend and I to have guests over because she doesn't like anyone but us. She starts growling and sometimes hissing at our guests. We rescued a cat recently that is not quite a year old. She was abused and abandoned by someone. She is super sweet but can hardly meow and her nails are so worn down and not sharp at all. She is still under weight and has no way to defend herself. I I have tried everything and still cannot get my old cat to accept the new cat. We have them in separate rooms and do the room switch and have a cloth by their food bowls with the other cats sent on them and etc. We are afraid that our cat will never accept our new cat. Please help!
