The Cat in the Hat Knows a Lot About That! is an American/Canadian/British animated television series that premiered August 7, 2010 on Treehouse TV in Canada, on September 6, 2010 on PBS Kids in the US and also in the UK on CITV and Cartoonito. The award-winning series is based on Random House’s Beginner Books franchise, The Cat in the Hat’s Learning Library, and is developed by Portfolio Entertainment, Random House Children Entertainment and Collingwood O’Hare Productions. The first season has 40 half-hour episodes. PBS Kids renewed it for a second season of 20 episodes which premiered on September 10, 2012.
Each episode features The Cat in the Hat, who leads six-year-old 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 at the beginning of each episode, which will inevitably lead them around the globe to "make natural science discoveries." Similar to other PBS Kids series such as Curious George and Sid the Science Kid, The Cat in the Hat Knows a Lot About That! focuses on introducing preschoolers to various science and learning concepts.
