Favorite and Dumb Butt

I have a favorite. That's right. Maybe I shouldn't say that out loud, but I do. She is definitely a Mama's girl.

Now Sally is ok. She is sweet to everybody but Kiki. Kiki I think wouldn't mind having a friend, but Sally hisses and pounces at her. I want to change Sally's name. I just don't like it. I thought that maybe we should call her something that rhymes, but she doesn't even look when we call her by her name. So when I finally said, "Hey Dumb butt look at me." She looked at me a bit annoyed, but she looked. So should her name be Dumb Butt?
