Jen, you are 100% correct!!! That six pound girl, Mimi, who is 13 years old, hisses at him every single time he walks near her. And Butter, who is probably 15 pounds, is scared of her!!!! LOL!!! I'm glad. Because if he hurt her a single time, he'd be out. She was here first. They have learned to co-exist, but she hates him. And on occasion, he just can't stand it, and must chase her!!! Wish he wouldn't, but she puts him in his place very quickly!! :D
Butter got his name, originally, because of his "butterscotch" highlights.........but your mom's reasoning is much more sound!!! LOL!!! I do love him though......don't get me wrong about that.
