Dave Mitchell and his father disagree on almost everything—and every time their fighting sets off his mother’s asthma, Dave ends up storming out of the house. But when Dave meets a big, handsome tomcat, he decides to bring him home, no matter what his father has to say about it. With adventure-loving Cat around, Dave meets lots of new people—like Tom, a young dropout on his own in the city, and Mary, the first girl he can talk to like a real person. And as his eyes open to those around him, Dave starts to understand his father a little better. They still don’t see eye-to-eye on a lot of things, but there is one thing they can both agree on: Having a cat can be very educational—especially when it’s one like Cat.
