The Cat in the Hat Knows a Lot About That! is a Flash-animated musical preschool television series featuring Martin Short as the voice of The Cat in the Hat, that premiered on Treehouse TV in Canada on August 7, 2010, also airing on YTV in Canada on weekday mornings from 2012 to 2013, and on PBS Kids and PBS Kids Go! in the US on September 6, 2010. It also aired on CITV and Tiny Pop in the UK. The show is based on Random House's Beginner Books franchise and The Cat in the Hat's Learning Library, itself based on the 1957 children's book The Cat in the Hat.

The show was produced by Portfolio Entertainment, Random House Children Entertainment, and Collingwood O'Hare Productions, in conjunction with KQED, PBS, Treehouse TV, and Kids' CBC. The first season has 40 half-hour episodes and ended on September 17, 2012.

In early 2012, the show was renewed a second season of 20 episodes, which premiered on September 10, 2012. However, episode 2 of the second season began airing on September 24, 2012. The second season ended on June 23, 2015. In September 2015, the series was canceled after two seasons.

A year later, the show resumed production. In September 2016, the show was renewed nine months later for a third and final season with 20 episodes. The third season premiered on March 2, 2018. In September 2018, the show was canceled again, ending after three seasons, and the series finale aired on October 14, 2018.

Premise
In the show, The Cat in the Hat leads neighbors Nick and Sally (and sometimes the Fish and Thing One and Thing Two) on a variety of adventures in his "Thinga-ma-jigger".

Researcher Natalie Jones stated that the "Thinga-ma-jigger" is a Seussian contraption that can sprout wings, fly, pontoons, booster rockets, change size and do just about anything else necessary to further the adventure (and accompanied by a rock tune composed by Harold Beckett under the title of "Traveling Song" that appears in each episode), which is prompted by a question posed by either Nick or Sally at the beginning of each episode, which inevitably leads them around the world to make natural science discoveries.

Like other PBS Kids-produced shows (such as Curious George and Sid the Science Kid), the show focuses on introducing preschoolers to various science and learning concepts.

Episodes

Characters

Main
 The Cat in the Hat (voiced by Martin Short) is a knowledgeable, adventurous, anthropomorphic cat. He loves to discover the world and act as Nick and Sally's guide, and he frequently speaks in rhyming patterns reminiscent of the Dr. Seuss character on which he is based.
 Nick (voiced by Jacob Ewaniuk in seasons 1 & 2 and Deandray Hamilton in season 3) is an African-American boy and Sally's next-door neighbor and best friend.
 Deandray Hamilton replaces Ewaniuk for season 3.
 Sally (voiced by Alexa Torrington in seasons 1 & 2 and Halle Nunes in season 3) is a blonde-haired girl and Nick's next-door neighbor and best friend.
 Halle Nunes replaces Torrington for season 3.
 Fish (voiced by Rob Tinkler) is a moderately pessimistic fish who is loosely based on the fish in the original story and whose color is changed to red starting with the show. However, he appears to belong to the Cat instead of Sally or Nick; he is also much more cooperative in the Cat's adventures and (along with Thing One and Thing Two) sometimes joins the Cat's adventures.
 Tinkler also voices Thing One and Thing Two, a pair of blue-haired creatures in red suits who are the Cat's helpers. They speak their own language (the one similar to incoherent gibberish) and (along with Fish) sometimes join the Cat's adventures.

Supporting
 Nick's mother (voiced by Tracey Hoyt) appears in some episodes. Whenever Nick asks permission to go on an adventure with the Cat, the answering voice is heard; she speaks with a Caribbean accent.
 Hoyt also voices Sally's mother who (like Nick's mother) appears in some episodes and, whenever Sally asks permission to go on an adventure with the Cat, the answering voice is heard.

Home media
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 the exception of a few, in Dolby Digital, in 5.1 surround and Dolby surround stereo in Spanish); each has the bonus segments from the show.
