1) So I moved in with a new roommate about 2 months ago. She has a cat; I have a husky mix dog. I also have a cat. The dog wanted to eat the cat, so after much patients and training the dog seems to be OK with the cat. Once in a while he’ll try and take a bite out of her, but usually he’s pretty good. My roommate is now kitten sitting a little kitten for her friend, and my dog wants to eat this kitten. I am wondering if there is a better way to adapt them to each other.

2) Now, for some reason MY cat has started to attack her cat (not the kitten) about a week ago. Yes, I moved into the apartment first, and my cat is most likely being territorial. However, she didn’t start this until a little while ago. She follows my roommate’s cat around and tries to attack her. We keep them apart when we are not home, but we want them to be able to be out together so ones not locked up for a long period of time in one room. Any thoughts on how to get my cat to stop beating the crap out of her cat? Both are females.

I would keep a very close eye on any interaction btw. your dog and the kitten. Your dog could very easily hurt or kill the kitten- by accident or because it really does want to kill it. I would strongly suggest keeping the kitten seperated in a room away from the dog.

The second part of your question.

Frankly I am surprised your cat got along at all with the other cat. For them to be acting up now is what I would have expected from the beginning. Cats are NOT likely to get along easily with other cats they were not raised with. They may be choosing a pecking order but in the mean time keep an eye on the 2 cats as well. Cats can hurt each other pretty badly if they decide to fight. I would keep all animals seperated when no one is home. When you or your roommate is home let them mingle but watch ALL OF THEM- your dog included. It may take some time for them to learn to live with one another- or they might never learn.
