One Moose, Twenty Mice by Clare Beaton. She especially likes it when I meow every time she points to the cat. The cats are a little of hard to find on most pages so I just point and meow myself. When I get to twenty mice she points at the cat over and over and over and I end up meowing like a crazy cat and she ends up giggling like a crazy kid, it's fun. I think the repetative nature of the book keeps her really entranced. She loves it.
