[[caption-width-right:350:"He knows a lot about, he knows a lot about, he knows a lot about that!"]]

An EdutainmentShow on Creator/PBSKids starring Literature/TheCatInTheHat (voiced by Martin Short), Sally, her new best friend Nick and Fish, plus cameos from Thing One and Thing Two. Each episode is composed of two twelve-minute stories, in which the Cat helps solve the children's problems by whisking them off in his helicopter-esque Thingamajigger to experience a relevant aspect of the natural world. This usually involves meeting and learning from an exotic animal, bird or insect.

The series is based loosely on a franchise of books called ''The Cat in the Hat's Learning Library'', which was later retitled to match the name of this television series.

!!This show contains examples of:

* AreWeThereYet: In "Itty Bitty Water," the Cat repeatedly moans this after the group has traveled across a long desert to reach a stream. Fortunately, the third time around, the answer is yes.
* BagOfHolding: The Cat's hat, as per the original, turns out to contain ''whatever'' might be needed for that day's adventure. The similarly-stuffed hatch at the back of the Thingamajigger probably qualifies too, given the Things apparently live there.
* CatchPhrase: When suggesting each new adventure, the Cat tells the kids "Your mother will not mind at all if you do..." [[CallBack referencing a similar repeated line from the books]]. Nick's constant variations on "That's ''so cool!''" may also count.
* ChristmasSpecial: ''The Cat in the Hat Knows a Lot About Christmas!''
* {{Cloudcuckoolander}}: Thanks to his role as responsible guardian to the kids, the Cat is actually quite a bit saner and more organized here than in the original... but he's still a Dr. Seuss character (as interpreted by Martin Short, to boot) and still prone to all it implies.
* ComeOutComeOutWhereverYouAre: Barry the barracuda sings a rap song that includes this phrase while he's hunting for his prey.
* DisembodiedEyebrows: Fish.
* DontTryThisAtHome: Before giving the kids bubble gum to help them stick to rocks like limpets, the Cat makes them promise never to try the same thing back home. "Your mother will most ''certainly'' mind if you do!"
* EdutainmentShow: Unlike a lot of the more recent offerings of this type, {{Aesop}}s or pro-social values aren't the primary goal. Instead, the show merely has some very interesting things to teach about science and nature, and particularly various types of animals. Even PeripheryDemographic watchers may learn something they didn't know before, such as the properties of the blue-footed booby's feet, or the various ways in which a wolf can find their pack.
* ExcitedShowTitle
* FantasyHelmetEnforcement: Part of the ritual preflight checklist before each adventure, as they settle into the Thingamajigger: "Buckle up! Flick the jiggermawhizzer!"
* LargeHam: Martin Short as the Cat. ''Good heavens'', Martin Short as the Cat.
* {{Leaning on the Fourth Wall}}: After they get permission from their moms to go on each adventure, the kids yell to the Cat "We can go! We can go!" and he ecstatically jumps into the air and bellows back "I know, I know!!". In one episode, they perform this ritual [[ItMakesSenseInContext in a small tent they've just finished putting up]]... leading the Cat to add a ''very'' calm "...and let's never do that in a tent again, OK?"
* MadLibsCatchPhrase: Used to set up the adventure in each episode:
-->'''Cat''': ...Your mother will not mind at all if you do!
-->'''Sally & Nick''': ''(running towards the back door)'' Mom! Can we go to [whacky place name] to meet/learn [specific skill] from [exotic creature]?!
-->''(Mom laughs and gives permission, with a quip that clearly indicates she thinks they're just kidding)''
* MobileFishbowl: Fish -- in this series apparently the Cat's companion rather than the children's pet -- travels with the group in a bowl that sits in a special cradle on the back of the Thingamajigger.
* OnlySaneMan: As per the original, Fish sees himself in this role in relation to the Cat's unbridled whimsy ("''Some''body's gotta take care of you!"). Sally also gets shades of it from time-to-time.
* PlutoIsExpendable: In "The Planet Name Game," the Cat, Nick and Sally travel into space and name the eight planets. Neither Pluto nor the controversy surrounding it are mentioned. Incidentally, this may be the first series of its type to touch the subject of naming the planets since the 2006 decision.
* RaceLift: In the books, the male child character was white, but the one in the TV series is black (and is a different kid, as evidenced by the fact that he's now Sally's neighbor instead of brother). Additionally, the new books being released under the banner of ''The Cat in the Hat Knows a Lot About That'' feature the the black youngster.
* RefugeInAudacity: In every episode, the Cat tells the kids to get a parent's permission before they can go on the day's adventure to meet [insert outlandish animal] in [insert whacky place name]. The parent always allows it, thinking they're just pretending.
* RhymesOnADime: The Cat, regularly and obviously, in the Seussian tradition.
* RuleOfThree: Relies fairly heavily on it as per most children's edutainment programs.
* RunningGag: See RefugeInAudacity above. Additionally, each episode features an interlude wherein Thing One and Thing Two are called on to get the travelers out of some difficulty, usually by building some wildly complicated contraption.
* SeldomSeenSpecies: Many episodes of the show are focused on animals and it often covers some more unusual ones, including the duck-billed platypus, booby birds, water striders... and, of course, the ever-rare hatted cat.
* TitleThemeTune: "Wherever you're going, wherever you're at, ''The Cat in the Hat Knows a Lot About'' (he knows a lot about, he knows a lot about, he knows a lot about...) ''That!''"
* ViewersLikeYou: Creator/{{PBS}} shows mandate a "thank you" at the end of the funding credits. The Cat takes this as yet one more opportunity to be supremely hammy. "And you and you and '''''you'''''! Thanks. So much. You're very kind."
* WhatHappenedToTheMouse: Originally, the main characters in ''Literature/TheCatInTheHat'' were the Cat, Sally, her brother, and their pet Fish. In this series, it's the Cat, ''his'' pet Fish, Sally, and a new African-American boy who lives next door, named Nick. What happened to Sally's brother? And when did Fish -- notoriously suspicious of the Cat in the original -- switch sides?
* WhosOnFirst: One of the quiz gags with Fish involves an owl that keeps hooting when Fish is trying to ask us his question about what sound an owl makes.
-->'''Fish''': You got it this time, but next time I'll stump you for sure.
-->'''Owl''': (''hooting'') Whooooo.
-->'''Fish''': Me, that's who!
* YouDidntAsk: In the Christmas special, this is Ralph the reindeer's explanation when Sally and Nick ask why he didn't tell them that he's one of Santa's reindeer.
