New in paperback, the second of an award-winning, hilariously funny middle-grade series about guinea pigs who act like other pets will move its author, Patrick Jennings, into the ranks of much-loved writers, such as Louis Sachar and Andrew Clements.When Rufus goes back to school, he learns that he and his guinea dog, Fido, are now celebrities. All his classmates want to see his pet, and some of them (the horrible Dmitri) even want to buy her. Rufus hates the attention so much he decides to remake Fido into a regular guinea pig, but then she disappears! Did she run away, did one of the kids kidnap her, or is she hurt? Never fear, Fido is found, and she is not alone! A new guinea pig is with her, and this one acts like a squirrel--just right for rodent-loving, chinchilla-brushing Lurena, the girl Rufus can't get away from.
