Finley wants--no, needs--a pet. But before Mom and Dad will even consider it, she'll have to prove that she's ready for some responsibility. When her next-door neighbor needs a last-minute pet sitter, it seems like the purr-fect opportunity. But Finley soon learns that taking care of a pet isn't all cuteness and cuddles--especially a cat like Goo-Goo. When Goo-Goo proves to be more than she can handle on her own, Finley enlists her brother and sister to help. While they don't always agree, together they come up with some creative ways to get the job done.
