Madam Scratchy Peaches runs a tight castle. She has her humans well-trained, her treats on schedule, and her belly scratches exactly when she wants them. But when Homie the dog moves in, everything changes. He's loud, he's messy, and he's completely unaware of who's in charge. Just when the Queen of Everything is ready to call for a royal revolt, she discovers that having another creature in the castle might not be so bad after all.
