Based on her previous bad behavior, the Society of Cat Aptitude has determined that Kitty is not only a bad kitty but a bad cat. In order to redeem her feline status, Kitty must take an aptitude test to determine if she deserves to be a cat. If she fails, she will no longer be able to be a cat. With the help of Chatty Kitty, who is the instructor at Cat School, and Uncle Murray, who thinks he's just there to renew his driver's license, Kitty learns all about being a cat and a little about herself.
