Hi. We brought a new kitten home from the shelter two days ago to be a playmate for a 3-year old stray we adopted last year. The kitten is 13-weeks old and we didn't follow the protocol for separating them. Needless to say, he (the older cat) is not happy. We do have a cage for the kitten and she sleeps in it at night. We do not allow her to use his dishes or toys, but she has romped around a bit and caused a stir. He growls and hisses - which he has NEVER done.
Is it too late to separate them and hope that they will work it out?
