My cat (not quite a year old) will not leave the new cat (around 4) alone. My friend is getting divorced and needed a home for him, so I took him in. he is a big sweetheart and gets along with the other two, even the dog. He's a big love bug. I knew we would take him as soon as I heard she was moving. The kitten keeps biting the new ones tail and starting fights with him and when I put them in separate rooms the kitten did outside the door and yells and yells (chattering) I don't know what to do. They are both males, the kitten will be getting fixed soon, all the others are fixed already. I don't know how to get them to get along!
