For anyone who has ever suspected that cats have their own secret society, this amusing book proves it. Three felines prepare to read Cat Secrets, a book so precious it's kept in a protective glass case. But first they need to make sure there are no non-cats around, and so they begin their investigations. They directly challenge readers to meow, purr, and stretch. The cats take some convincing and are so preoccupied with this that they do not see a mouse sneaking around them, angling to snatch the book himself. The cats' willingness to read their secrets aloud hinges on one final test — taking a nap — which they proceed to do, giving the mouse free access to the tome.
