Simon has taken care of his owner, Andy, for many years. He's a good cat. Clean, responsible, and loyal. What more could a boy want? Even when Andy's dad moves out, Simon is certain that Andy doesn't need another pet. So why would Andy's dad adopt a DOG? To make matters worse, the animal is a rude, rowdy troublemaker.

Simon's job is clear: the beast has got to go. He decides to write him a letter. Strongly worded, of course. But when the dog's response sets off an unexpected correspondence, Simon realizes the beast may be here to stay. Can he make room for another pet in Andy's life?

This funny and heartwarming collaboration between Geisel Honor and Edgar Award-winning author Dori Hillestad Butler and bestselling illustrator Kevan Atteberry is a tribute to the love of a good pet - and the joy found in new friendship. With nine chapters and adorable full-color illustrations on every spread, the series is perfect for kids transitioning from picture books to chapter books.
