Comet, the cat, appears to be just about the sole feline in a Nantucket otherwise populated by nattily dressed canines. In search of a home, as well as adventure, the roaming cat meets with peril. Snoozing in a bookstore, he is buried under a pile of books; taking a ride on a scallop boat, he's swept overboard by a huge wave; visiting an ice cream shop, he falls headfirst into a milkshake. Though some of these scenarios have comic potential, all eight of them prove fatal to poor Comet, whose ghostlike, winged image is in each case seen fleeing the scene.

The Nantucket setting is lovingly shown and expertly woven into every picture. Elaborate borders are fashioned with shells, wildflowers, and fishing line; the island is populated by dogs, all quite realistic looking and all wearing human clothes.
