For anyone who loves cats, dogs (or both!), James Patterson's most pawsome story ever is set in a society defined by the oldest rivalry in the world: katts versus doggs! Oscar is a happy dogg—-a rambunctious kid who loves being a Dogg Scout. Thanks to his family, he knows that snobby katts are good for nothing but chasing up trees. Molly is a clever katt who just knows she's destined for fame and fortune as an actress. She comes from a family of well-bred katts who despise drooly, disgusting doggs! For their whole lives, Oscar and Molly have been told that katts and dogs hate each other. One day, they each get hopelessly lost in the woods, but those lifelong prejudices flare up when they cross paths. Slowly, they realize that the only way to survive and find their way home is to...work together?! Yeah, that's not going to happen!

In this funny and paw-some story, lifelong rivals Molly and Oscar are forced to team up and brave the great outdoors and help their families before it’s too late. Wilderness adventurers and expert trackers Molly the katt and Oscar the dogg go camping with their families: parents, siblings, cousins, aunts, and uncles. One big reunion! It would be fun if there weren't so many rules to follow at the campsite. ATTENTION KATTS AND DOGGS: No crossing the border, or you'll be asked to leave the Eastern Wilderness Reserve. If you're still alive. Molly and Oscar must outsmart the rule-makers when they discover that their katt and dogg cousins have run away together—for reasons only Molly and Oscar will understand. Now the clever pair must find and warn their cousins before all four of them are in need of a serious rescue mission.
