Truffles the cat is the only pet in the house and reigns in peace and quiet, only exerting himself to find the best place to take a nice, long nap-preferably in a spot of warm sunshine. Then Poppy the puppy bursts onto the scene. Poppy is loud, enthusiastic, excitable, and-worst of all-a puptective! She's got an eye for crime and a nose to solve all mysteries that come her way... even though she's not completely sure what a mystery is. Truffles cannot let this intrusion stand. Poppy won't be able to continue disrupting his precious me-time if she's shipped to the North Pole! But could this irrepressible new companion be just what this grumpy cat needs?
