This book is written from the perspective of a cat named Ego. Like it says on the cover, it's a bedtime story. It's a good bedtime story for children because it's very short so parents won't be up all night reading the book to them, near the end Ego yawns and we all know how contagious yawns are, and, at the end of the story Ego says 'it's time for me to go to sleep. And, shouldn't you be doing the same? Good night.
