This is the story of a young boy called Peter, who is knocked down by a car. To his considerable astonishment, when he recovers, he is not a young boy, but a cat!

Fortunately, he meets Jennie, a cat who had been abandoned by her family when they moved away, who educates him in the wiles of the feline world. Will he stay a cat with Jennie, or return to being a human boy?
