The dog is sick today, but have no fear--the cat is happy to take his place! But when the book (who is very bossy) tells her to dig a hole, the dirt-averse cat finds a way to accomplish the task while keeping her fur pristine. And when the book demands that she fetch a stick (in the water!) or guard a sheep (from a wolf!), the cat responds in very un-doglike ways. Can the book and the cat reach a happy ending?
