Mom thinks that if she says a word twice, its easier for cats to understand.
I mean, when she wants my attention, she says, "Here Kitty-Kitty." Hey, I know I'm a Kitty. Maybe, I just don't want to come over there right now.
Or, she'll toss the toy mouse and say, "Go get your mouse-mouse." Well, it's a toy mouse. Duh. Maybe, I just don't want to chase it right now.
