This book is fabulous. I bought one for each of my grandchildren and myself. We live very far apart, but with each having their own book, I can read it to them over the phone and they can follow along on their end. The oldest is 5. The book's creators and illustrator had an imagination that would not quit. What a concept, a cat that is home alone all day decides to enter pictures on the wall and then with wit and rhyme describe his adventures. The pull out feature on the illustrations give you 3D vision of his journeys. This book may surpass Dr.Seuss, if you can imagine that.
