is an animated musical educational children's television series feature starring Martin Short as The Cat in the Hat.

The series premiered on Treehouse TV in Canada on August 7, 2010, also airing on YTV and Nickelodeon Canada on weekday mornings from 2012 to 2013,[2] and on PBS Kids and PBS Kids Preschool Block in the US on September 6, 2010; it also aired on CITV and Tiny Pop in the UK, and Disney Junior India.

In the show, The Cat in the Hat leads neighbors Nick, Sally (and sometimes 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, fly, pontoons, booster rockets, change size and do just about anything else necessary to further the adventure.

Each episode is prompted by a question posed by either Nick or Sally at the beginning of each episode (along with the "Travelling Song" — a rock-'n'-roll song written by Harold Beckett, with The Cat in the Hat saying a varied quote from Dr. Seuss that ends with a vowel —),[5] that in turn inevitably leads them around the world to make natural science discoveries.

NCircle Entertainment released DVDs from October 25, 2010 to June 27, 2016: each being in region 1, subtitled in English and Spanish; approximately 60 minutes (with a few exceptions); in Dolby Digital, in 5.1 surround and Dolby surround stereo in Spanish.
