Jonathan has a very unusual dog. It likes to go to the park, watch TV, and eat toast crumbs. And it's invisible. When the entire family — including Dog, of course — visit Grandma one day, Jonathan spots a photo of a cat. The cat, says Grandma, was hers, but the cat died, and Grandma's apartment won't let allow pets. The next day, Dog is gone. Jonathan explains to his family that he left Dog at Grandma's to keep her company... and it's okay if she calls him Cat. Inspired by the author's real-life children, who had their own invisible dog when they were young.
