Performer(s) Appeared in The Cat in the Hat is the titular character from the 1957 children's storybook of the same name, written by Dr. Seuss. As his name suggests, he is a six-foot-tall anthropomorphic feline wearing a stovepipe hat. As the book was one of Seuss' most popular stories, the Cat starred in a sequel, The Cat in the Hat Comes Back, published the very next year, and has since appeared in several other Dr. Seuss books and television productions (including one animated special where he battled The Grinch). However, he never starred in a Christmas production until the advent of his educational television series The Cat in the Hat Knows a Lot About That!, produced nineteen years after Seuss' death.
