The Cat in the Hat The Cat in the Hat The Cat in the Hat is a children's book written and illustrated by Theodor Geisel under the pen name Dr. Seuss and first published in 1957. The story centers 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 fish, the Cat shows the children a few of his tricks in an attempt to entertain them. In the process he and
The Cat in the Hat read, and Spaulding provided Geisel with a similar list. Geisel later told biographers Judith and Neil Morgan that Spaulding had supplied him with a list of 348 words that every six-year-old should know and insisted that the book's vocabulary be limited to 225 words. However, according to Philip Nel, Geisel gave varying numbers in interviews from 1964 to 1969. He variously claimed that he could use between 200 and 250 words from a list of between 300 and 400; the finished book contains 236 different words. Geisel gave varying accounts of how he conceived of "The Cat in the Hat".
