Cattus petasatus

The Cat in the Hat is a 1957 children's book written and illustrated by American author Theodor "Dr. Seuss" Geisel. The story centers on a tall anthropomorphic cat who wears a red and white-striped top 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 fish, 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, take over the house. Geisel created the book in response to a debate in the United States about literacy in early childhood and the ineffectiveness of traditional primers such as those featuring Dick and Jane. Geisel was asked to write a more entertaining primer by William Spaulding, whom he had met during World War II and who was then director of the education division at Houghton Mifflin. However, because Geisel was already under contract with Random House, the two publishers agreed to a deal: Houghton Mifflin published the education edition, which was sold to schools, and Random House published the trade edition, which was sold in bookstores. Geisel gave varying accounts of how he created The Cat in the Hat, but in the version he told most often, he was so frustrated with the word list from which he could choose words to write his story that he decided to scan the list and create a story based on the first two rhyming words he found. The words he found were cat and hat. The book was met with immediate critical and commercial success. Reviewers praised it as an exciting alternative to traditional primers. Three years after its debut, the book had already sold over a million copies, and in 2001, Publishers Weekly listed the book at number nine on its list of best-selling children's books of all time. The book's success led to the creation of Beginner Books, a publishing house centered on producing similar books for young children learning to read. In 1983, Geisel said, "It is the book I'm proudest of because it had something to do with the death of the Dick and Jane primers." Since its publication, The Cat in the Hat has become one of Dr. Seuss's most famous books, with the Cat himself becoming his signature creation, later on becoming one of the mascots for Dr. Seuss Enterprises. The book was adapted into a 1971 animated television special, a 2003 live-action film, and an 2026 upcoming animated film, and the Cat has been included in many pieces of Dr. Seuss media.
