Twelve-year-old Katie is dreading a boring summer alone in New York City while her best friend is away at camp—something that's way out of Katie and her mom's budget. That is, unless Katie can figure out a way to earn the money for camp herself. But when Katie gets a job cat sitting for her mysterious upstairs neighbor, Madeline, life gets interesting.

For starters, Madeline has 217 cats (!) and they're not exactly . . . normal. Also, why is she always out EXACTLY when the city's most notorious villain commits crimes?! Is it possible that Katie's upstairs neighbor is really a super villain? Can Katie wrangle a whole lot of wayward cats, save a best friendship (why is Beth barely writing back? And who's this boy she keeps talking about?!), AND crack the biggest story in the city's history? Some heroes have capes . . . Katie has cats!

With irresistible illustrations and laugh-out-loud humor, Katie the Catsitter is a feline-friendly adventure that shows how, with the right catitude, anything is pawsible!
