A stuck-up cat and a good-natured dog are pen pals from a distance, until a disastrous sleepover brings them together in this playful illustrated chapter book told in letters. Andy has two pets and two houses: a cat, Simon, at his mom's house and a dog, Baxter, at his dad's house. But when Andy's mom goes on a business trip, Simon must spend a few nights at Andy's dad's house. A sleepover with the beast? Simon says, "No, thank you." Baxter, on the other hand, is sooooo excited to play together.
