It's fun to be a Baby-sitters Little Sister! We Heart Cats! Karen's best friend Hannie just got a new kitten. Now all her friends have cats. And Karen has a great idea. She can start a club like her big sister Kristy. It will be a Kittycat Club! What will the club do? Karen can't baby-sit like Kristy . . . but she can cat-sit! Will anyone want Karen as a cat-sitter? They'd better-running a club is hard work!
