Advice/experience greatly appreciated!!!
A friend of ours found a kitten and took it in. She had it all checked over etc but it didnt get along with her cat. She was getting desperate to get rid of it so we took it. We already have 2 cats. I brought it in tonight, isolated it in the bathroom but one of the cats has thrown a right paddy. Keeps growling and hissing at me. I'm going to start scent familiarisation with them for a few days and not let them have contact but do you think it will get better or was i being a bit naive???Vet has said kittens a boy and my other 2 are girls.
Help!!!
