Will anyone believe four cats are the source of Holly's trouble?Holly has a lot to deal with lately. Her mom has remarried and she has to get used to a new town, a new house, a new school, and a new stepdad. As if this isn't enough, she has to share her room with four pesky cats. Or rather, they have to learn to share their room with her. Max Cat always escapes. George Cat always disappears. Wilbur Cat eats socks. And Boo Cat is always somewhere you don't want him to be. These cats are driving Holly crazy. She can't get her homework done, all of her socks have holes in them, and the police even pay a visit to her house all because of the cats. Can Holly and the troublesome felines ever learn to get along?
After a difficult first week of third grade, Holly begins to adjust to her new life.
