The Cat in the Hat is a children's book written and illustrated by Theodor Geisel under the pen name Dr Seuss and fi rst published in 1957. The story centres on a tall anthropomorphic cat who wears a red and white-striped hat and a red bow tie. The Cat shows up at the house of Sally and her brother one rainy day when their mother is away. Despite the repeated objections of the children's fi sh, the Cat shows the children a few of his tricks in an attempt to entertain them. In the process he and his companions, Thing One and Thing Two, wreck the house. The children and the fi sh become more and more alarmed until the Cat produces a machine that he uses to clean everything up and disappears just before the children's mother comes home. The book was published to immediate critical acclaim. Some reviewers praised the book as an exciting way to learn to read. The book was adapted into a 1971 animated television special and a 2003 live-action film.
