->''"Whoever heard of a six-foot cat!?"''
-->--'''Mr. Krinklebine'''

''The Cat in the Hat'' is a [=DePatie=]-Freleng 1971 animated adaptation of the famed Creator/DrSeuss [[Literature/TheCatInTheHat book of the same name]]. It was the first Dr. Seuss special not to be directed by Creator/ChuckJones, whose studio shut down during its production (Jones is still credited for storyboarding). It stars Creator/AllanSherman as the titular Cat.

The special, written by Seuss himself, [[AdaptationExpansion expands upon]] and [[PragmaticAdaptation drastically changes]] the storyline from a RandomEventsPlot to the Cat enlisting the help of two children to help him find his missing "[[MacGuffin Moss-Covered Three-Handled Family Gradunza]]." As with the book, the children join in the cat's chaos at the behest of their finicky fish [[NamedByTheAdaptation here named]] [[AlliterativeName Carlos K. Krinklebine]] (voiced by Creator/DawsButler), and the cat cleans up on his way out before their mother comes home to find them out.

This version of the Cat appeared in two other Seuss specials, ''Dr Seuss On the Loose'' (where he introduced adaptations of ''The Sneetches'', ''The Zax'', and ''Literature/GreenEggsAndHam'') and ''WesternAnimation/TheGrinchGrinchesTheCatInTheHat'' (in which the Cat matches wits with Seuss's [[WesternAnimation/HowTheGrinchStoleChristmas second most popular character]]).

!!The animation provides examples of:

* AdaptationalConsent: Non-sexual example. In the original, the Things had to be netted in order to return to the box. Here, they do so of their own volition as soon as they hear the kids' mother returning home.
* AdaptationExpansion: The only parts of the original book present in the special are the Cat playing "Up Up Up With A Fish," the characters of Thing 1 and Thing 2 and the Cat cleaning up after himself. The rest is a completely new story about the cat looking for his MacGuffin. Justified, in that the original book [[RandomEventsPlot didn't really have a plot]] to begin with.
* AsLongAsItSoundsForeign: In "Cat, Hat", the Cat gives accurate translations of his name in French, Spanish, German and Russian. But in the same breath he says that he's "a ''gwunka'' in a ''bunka-kwunk'' in Eskimo". No Inuit language has words remotely like this; this being 40 years before Google Translate, it seems Dr. Seuss just made up some gibberish to complete the rhyme scheme. Interestingly, you could still make a rhyme out of an accurate translation - in the Yup'ik dialect, for example, you could call him a ''kuuskaq'' in a ''nacarpiaq.''
* BigLittleSister: Sally appears to be at least as tall as her brother, although she is supposed to be younger than him.
* BilingualRhyme: When the Cat in the Hat is singing his name in different languages, he rhymes "chapeau" with "sombrero".
* BookEnds: The first scene of the special is the children sitting and staring boredly out the window as it rains, while their mother leaves. The last scene has the kids sitting by the window again as their mother returns, claiming she saw the Cat with the moss-covered three-handled gradunza, and the children have mystified expressions as they watch the Cat leave.
* CanisLatinicus: "Calculatus Eliminatus."
* DisneyAcidSequence: "I'm a Punk" and "Cat, Hat" both devolve into this.
* TheEndingChangesEverything: After the mom notices how a cat passed by with a "moss-covered, three-handled family gradunza" (his umbrella), you realize that The Cat made the entire ploy off the top of his head to give the kids some fun.
* FollowTheBouncingBall: Interestingly, ''The Cat in the Hat'' seems to have received the sing-along treatment more times than Dr. Seuss' other cartoons have; in addition to the Dr. Seuss' Sing-Along Classics VHS released in the '90s, the 2012 Deluxe Edition DVD and Blu-ray[[note]]released on the same day that the movie version of ''WesternAnimation/{{The Lorax|2012}}'' came to DVD and BD[[/note]] include an upgraded sing-along option.
* HaveAGayOldTime: A lyric in "Calculus Eliminatus" is "don't go to pot," which at the time was simply meant to mean "don't get worked up." The lyric in and of itself sounds a bit funny today, but as it happens ''a few seconds later'' one of the kids writes down "42-0" on the fishbowl!
* GratuitousForeignLanguage: "Cat, Hat" goes through ''several'' of them in rapid succession with his IAmSong. The chorus alone goes through Spanish, French, German and ''Eskimo''.
* IAmSong: In which the Cat lists the many ways to say his name in other languages, including with a [[https://en.wikipedia.org/wiki/Schnitzelbank Schnitzelbank]]-style ditty [[GratuitousGerman for German]].
* InformedAbility: According to the Cat, Thing 2 and Thing 1 can "find anything, anything under the sun." They spend most of their number playing with the fishbowl, and most of the next number acting as backup dancers.
* {{Irony}}: The kids are bored, but the first song that's played highlights all of the toys that are littered in the house that ''they aren't playing with!''
* ItWasWithYouAllAlong: Invoked. The special item the Cat wanted was his umbrella, thus with him always. But the kids didn't know that till the mom told them so.
* JerkassHasAPoint: Near the end of "Cat, Hat", the fish finally "gets it", then chips in with his own contribution by saying what the Cat would be called in Russian. The Cat is impressed on both counts.
* MacGuffin: The one he is searching for is his "moss-covered, three-handled family gradunza"... whatever that means.
--> '''Fish:''' Just what is a family gradunza?\\
'''Cat:''' Oh, they come in all sizes, from tripe-G to minus-aught.\\
'''Dick:''' Is it bigger than a--\\
'''Cat:''' Occasionally, but on most occasions, not.\\
'''Sally:''' Is it smaller than a--\\
'''Cat:''' They no longer make that kind, but one family gradunza is always smaller than another.
** When the mother returns, she notes that the Cat in the Hat had said MacGuffin in his hands. It's assumed that the item was actually his ''moss-green colored umbrella''. Which would explain the expression of the kids when they hear it.
* MusicalChores: "Sweep Up the Memories", as the Cat is cleaning up the house and restoring it to pristine condition before Mom enters.
* NamedByTheAdaptation: The Fish, unnamed in the book, is named Carlos K. Krinklebine here.
* NotSoAboveItAll: The Fish spends most of the special angrily demanding that the Cat leave, only to happily join in midway through the "Cat, Hat" number.
* OffscreenCrash: During the “Chapka in a Shlyapa,” the Cat goes through a doorway while trying to do ThatRussianSquatDance and the camera stays on the doorway while the screen shakes as the Cat crashes into stuff before hopping back out, disheveled.
* PerfectlyCromulentWord: The lyrics were written by Dr. Seuss, so of course. In a moment of dejection, the Cat sings that he is "a cretunkulous shnunk," and continues:
--> I agree, I'm a grifulous grofulous grue.\\
I'm a shmoozler! A smankler!\\
And a poopoobler too!
* RewatchBonus: After the ending twist, go back and notice how the Cat never actually explains ''what'' his Moss-Covered Three-Handled Family Gradunza" looks like, always cutting the kids off when they ask him questions on what it actually looks like.
* ShoutOut: The "Cat, Hat" number features quotations of Music/TheCancanSong, Schnitzelbank, and "O du lieber Augustin".
* StrangeMindsThinkAlike: The mother knows what a moss-covered, three-handled family gradunza is.
* ThoseTwoGuys: The kids are only given 1 scene apart from each other, and their personalities are essentially interchangeable.
