Nothing But Trouble, Trouble, Trouble — Patricia Hermes

Getting into trouble is Alex's specialty.

Alex is always getting into trouble -- but not on purpose. Especially not this time, because if she doesn't get into trouble it will prove to her parents that she's grown-up. Grown-up enough to baby-sit -- and maybe even get her ears pierced.

Alex thinks her special science project of taking care of a pet over the weekend will be just the thing to prove to her parents she's serious. But Alex's younger sister, Meg, is allergic to pets, so Alex decides to "borrow" two cats from the snobby girl next door. Before Alex knows it, the cats are loose in the house, Meg is sneezing nonstop, and her parents are furious. Staying out of trouble isn't going to be easy!
