We've had Mimi now for two years and she doesn't seem to really get along with the other two cats. In fact, they all don't seem to really care about each other much. Bear is our second cat. He and Tabitha, our first cat (who has been gone now four years) loved each other very much and would cuddle together all the time. All three of the cats now will lay on the same bed, but pretty much stick to their own corners and don't really have much to do with each other while wandering around the house. Sometimes Cookie and Mimi will harass each other. But, I think that's just because Cookie gets bored and needs something to do...
