The Cat in the Hat Knows a Lot About That! has 40 half-hour episodes. PBS Kids renewed it for a second season of 20 episodes which premiered on September 10, 2012. A 20 episode third season is currently in development. Each episode features The Cat in the Hat (voiced by Martin Short), who leads neighbours Nick and Sally, the Fish, and Thing One and Thing Two on a variety of adventures in his "Thinga-ma-jigger", a Seussian contraption that can sprout wings, pontoons, booster rockets, change size, and do just about anything else necessary to further the adventure. The adventures are prompted by a question posed by either Nick or Sally
The Cat in the Hat (film) was being made that a live-action version of "The Cat in the Hat" just wasn't a great idea." Ebert had the same problem with the film that he had with "How the Grinch Stole Christmas", in that "If there is one thing I've learned from these two movies is that we don't want to see Jim Carrey as a Grinch, and we don't want to see Mike Myers as a cat. These are talented comedians, let's see them do their stuff, don't bury them under a ton of technology." Concerns were also raised over the PG rating of the film
