No favorites here.......I love Mimi because she is just so easy, and seems to fit into whatever situation she is faced with. She is 13 years old (young) and is as lovable as the day she came to live with me (six weeks old). But Butter came as a mean adult cat, and I mean, MEAN. But I love him dearly and since our move, three weeks ago, he has become a different cat. No meanness to him anymore. Hurray!! I've always said that if I had to choose only one of my multiple pets (3 dogs, 2 cats, 2 Cockatiels and a hamster), it would be Mimi, but only because she has been here the longest and been through every life change with me. But I love them all equally.
