A thunder storm, a power outage, several break-ins, and a missing pet launch Stephen Noble and Renée Kobai into action. All the crime victims are Noble Dog Walking clients who, one by one, find other ways to exercise their dogs. Unless Stephen and Renée find the real criminal fast, they may find themselves cat sitting instead. The local animal control department turns out to be no help either. All they care about is their annual cat sale. When Stephen and Renée lose their favourite clients, Jack Russell Ping and rescue greyhound Pong, they pin their hopes on gathering all the suspects at the animal control and a real cat-astrophe ensues.
