ExactlyWhatItSaysOnTheTin: [[AttackOfThe50FootWhatever Really Big Cats.]]

Just the thing for dealing with RodentsOfUnusualSize, but be wary of CanisMajor. Subtrope of AnimalsNotToScale and/or CuteGiant.

This trope is about cats that are exceptionally larger than is the norm for their species. For the standard "lions and tigers" variety of big cat, see PantheraAwesome. Fictional CatFolk species do not count for this trope, however big they may be.

The name is a combination of ''Mega-'' from Greek ''megas'', meaning large or great, and ''Neko'' from the Japanese word for cat. It should not to be confused with {{Meganekko}} (two Ks, one word), which is about how bespectacled girls are cute. However, ''do'' compare with CuteKitten. If this trope and {{Meganekko}} do overlap, she'll be a FunnyAnimal, GeniusBruiser and CuteMonsterGirl.

!!Examples

[[foldercontrol]]

[[folder: Anime & Manga ]]
* The pictured cat's time as [[Anime/MagicalGirlLyricalNanoha Nanoha's]] mount proved to be short-lived, as it was quickly defeated by Fate in her first battle against Nanoha in one of the most tragically hilarious boss battles in the series.
** Got upgraded to a PantheraAwesome that could grow wings in TheMovie. It was probably a good thing that Fate went on the attack this time.
* The New Years Day Special episode of ''KimagureOrangeRoad'' has 'Jingorojira', a [[Franchise/{{Godzilla}} Godzilla-sized]] version of Jingoro, the Kasugas' much-suffering housecat.
* Kotatsuneko from ''Manga/UruseiYatsura'' and Maomolin the Bakeneko from ''Manga/RanmaOneHalf'' are both huge ghost cats.
* From ''Manga/AzumangaDaioh'': Chiyo-Dad![[note]][[MindScrew Except when he isn't...]][[/note]]
* Kamisama, the wacky, color-changing, vending machine-dwelling, KingOfAllCosmos cat-thing with a VerbalTic from ''PaniPoniDash''.
* Cait Sith in the ''Manga/{{ARIA}}'' series. As a King of Cats, it only makes sense he's more than human-sized.
* [[UnluckyEverydude Tasuke]] is attacked by one in ''MamotteShugogetten'' as a trial by a [[SealedGoodInACan newly-awoken spirit]].
* Saber Leomon and Bancho Leomon are Mega leveled Neko Franchise/{{Digimon}}. Regular old Leomon does deserve a mention though considering he's taller than most adults.
** Other digimon examples include the tiger Deva Mihiramon, Lynxmon, and [=DinoTigemon=], to name a few.
* The Cat Bus from ''Anime/MyNeighborTotoro'', which is ExactlyWhatItSaysOnTheTin. In Japanese folklore, cats, like {{tanuki}}, [[VoluntaryShapeshifting can change shape at will]] - so the Cat Bus is an ordinary cat who got bored and decided to spend some time being a bus. As you do.
** In the short film/sequel ''Mei and the Kittenbus'', the titular kittenbus is about the size of a child's toy car-- [[http://www.nausicaa.net/miyazaki/museum/mei/images/Page1_small.jpg just big enough to hold Mei]]-- but we also find out that there are [[http://www.nausicaa.net/miyazaki/museum/mei/images/Page2_small.jpg cattrains]] and what can only be described as a [[http://www.nausicaa.net/miyazaki/museum/mei/images/Page3_small.jpg catliner.]]
* Kyaa from ''PleaseSaveMyEarth'', the giant cat-like alien companion of Shion's adoptive father, named after the scream people let loose upon seeing him for the first time. (Shion uses Kyaa as a bed at one point.)
* Kirara from ''Manga/InuYasha''. Spends most of the time at normal cat size, but gets big enough to ride when needed.
* In ''Battle B-Daman'', Armada is a cat who appears to have his eyes closed all the time, whatever that means in anime. He's pudgy, which is set off somewhat by his head being about a third of his body, and he's tall in relation to the more humanoid characters.
* In ''Shinzo'' (''Mushrambo'' in Japan), Kutal is a cat creature who also has that type of eyes. His height isn't a whole more than his companions', but he's quite rotund. Then there's his leonine hyper-form, which is much less bulky and much more badass.
* ''Manga/CardcaptorSakura'' episode 31, a cat enlarged by the Big Card (playfully) attacks Syaoran and Meiling. It returns to normal once Sakura seals the aforementioned card.
** In another episode, Sakura is shrunk by the Little Card and runs into a cat which, compared to Sakura, is a MegaNeko. It tries to eat her.
** And [[FairyCompanion Kero]] himself, once [[TransformationSequence his powers are fully unlocked]], becomes [[CrowningMomentOfAwesome a fire-breathing winged lion]]. Too bad [[TheWorfEffect his powers often end up being useless]] against the MonsterOfTheWeek...
* In ''Ultra Maniac'', episode 7: 'Gigantic Pets', a magical growth-portion makes its rounds at the school. Among the 'victims' is Sakura's familiar, the usually-tiny kitten, Rio. By the time the girls realize what's happening, he's eye-height with them, and still growing. By the end of the episode, it can barely fit in the gym-hall.
* In general, ridiculously huge cat-like monsters are often used in the role of a MonsterOfTheWeek. Examples can be found in ''Anime/SailorMoon'', ''manga/TokyoMewMew'', ''BlueSeed'', and probably in other series.
* [[NamesToRunAwayFromReallyFast Kuma]] in ''{{Sketchbook}}''. When one of Sora's friends mentions coming across the bear-like cat, Sora corrects how big his head width was. Yeah, he's a big kitty (but still manages to beat Mike in a height superiority contest).
* The tank in ''ThoseWhoHuntElves'' gets possessed by a cat spirit. Just pause for a moment to consider the behavior of a tank that thinks it's a kitten...
** Under that same concept, one Ranma Saotome when he's been bugged by a cat that little bit too long..
* ''Manga/{{Naruto}}'' has the two-tailed beast Matatabi, who is a giant nekomata (a two-tailed cat)
* ''NagasareteAirantou'' has Taiga and Shima-tora, the Northern and Southern leaders, both giant two-tailed cats.
* The [[EvilMakesYouMonstrous Bakeneko]] of ''Anime/AyakashiSamuraiHorrorTales''. Unlike most of the examples on this page it is ''not'' cute.
* ''Manga/{{Rinne}}'' has Rokumon the black cat, who sometimes is one of these. Let's just say Creator/RumikoTakahashi seems to love this trope.
* The demonic cats sent by Emperor Ganishka to Vritannis to terrorize the denizens in ''manga/{{Berserk}}''.
* Nekomaru from ''KidouShinsengumiMoeyoKen''.
* In the first episode of season 3 of ''UFOPrincessValkyrie'', Cat-Eared Maid-Chief Sanada-san breaks out a [[HumongousMecha Mecha-]]MegaNeko in order to fight a [[{{Brainwashed}} Brainwashing]] {{Meganekko}}. She counters by giving it a gigantic pair of glasses, thus turning it into a [[OverlyLongGag Mecha-Meganekko-Mega-Neko]]. Perhaps a borderline example, but too awesome not to mention.
* Nyanko-Sensei from ''Manga/NatsumeYuujinchou'' is quite portly in general, being occasionally referred to as a 'pig-cat' - and when he jumps out of SleepModeSize, he's a huge ''[[CanisMajor dog]]''. But the point where he really turns into this trope is in episode 12, when he comes into contact with a curse-mark that screws his powers up. His SleepModeSize shrinks to the size of a teacup, making him [[RidiculouslyCuteCritter hilariously cute]], but when he attempts to assume his 'true' form, he instead winds up as... a severely overweight cat the size of a small elephant.
* The villain of the third arc of ''LightNovel/JinruiWaSuitaiShimashita'' uses a large number of {{blob monster}}s to turn into a giant housecat at one point. This MakesSenseInContext. Slightly.
* Kaen of ''Manga/CatParadise'' is a nekomata who's at least ten feet tall. He's apparently able to make himself smaller at will, but only exhibits this once before becoming monstrous. On another note, [[MightyGlacier Musashimaru]] can potentially grow to several stories with the help of his owner's PowerUpFood.
[[/folder]]

[[folder: Comic Books ]]
* Adrian Veidt's genetically modified pet Bubastis in ''ComicBook/{{Watchmen}}'', a large pink lynx.
* [[LightNovel/DirtyPair The ''Lovely Angels'']] have Mughi, their technician/partner/pet: He's essentially a huge alien puma with a sharp mind, claws that can tear through hullmetal, and mental command over the electromagnetic spectrum thanks to his facial tentacles. (He also has an addiction to bad soap operas, according to Warren and Ellis..)
* Rock Jaw in Jeff Smith's ''{{Bone}}''.
* Explored in the ''ComicBook/TheSandman'' short story "Dream of a Thousand Cats": According to Dream, cats were initially on top of the food chain, towering over humans like they now tower over rats. Humans changed this by [[ClapYourHandsIfYouBelieve simultaneously dreaming of a world]] where they were at the top. The cat protagonist then goes off to try to convince a thousand cats to turn the world back into what it was--but [[HerdingCats have you ever tried to get that many cats to all do the same thing?]]. The story ends with one kitten dreaming of that world... but no need to worry, since it's implied she's the only one.
* [[FrancoBelgianComics Franco-belgian comic]] ''[[{{Melusine}} Mélusine]]'' has the titular protagonist face at one point a giant black cat. Makes even more sense if you consider his assistant is superstitious and actually afraid of black cats.
* One Italian DonaldDuck [[ComicBook/DisneyDucksComicUniverse comic]] had Donald's pet tomcat Tabby (who had appeared in a few comics before, usually as a foil to Fethry) drink a mysterious growth serum and grow to be bigger than a tiger. Interestingly enough, Tabby did not return to his normal size at the end of the story, and has not appeared in any comics since then.
* Comicbook/{{Saga}} has Lying Cat, a giant blue-green cat resembling a Sphynx, and can tell if someone is lying or not.
[[/folder]]

[[folder: Fan Fiction]]
* Shamisen, Kyon's cat, at one point of ''Fanfic/KyonBigDamnHero''. [[spoiler:Achakura]] referred to it using the trope name, having read this very page.
* After it's Prologue, ''Anime/MagicalGirlLyricalNanoha'' fanfic ''FanFic/GameTheory'' begins with the same giant cat incident that occurred in the anime. In the fic, the cat in the trope image is a girl kitten named Vesta, and while she still doesn't stay giant for long she [[ChekhovsGunman reappears later in the story]] [[AscendedExtra with an]] [[OCStandIn expanded role]].
* FanFic/AGrowingAffection lets the Two-Tails from canon throw down at full size on two different occasions.
[[/folder]]

[[folder:Film]]
* In ''TeamAmericaWorldPolice'' the team is menaced by a "panther" that is very clearly just a regular house cat. In this case, the fact that the characters were all marionettes meant that they didn't even have to cheat to make the cat look big.
* [[http://tfwiki.net/wiki/Ravage_%28ROTF%29 Ravage]] from Film/{{Transformers}}, isn't he just adorable?
* One of the alley cats that threaten WesternAnimation/TomAndJerry during the BigLippedAlligatorMoment from the infamous ''WesternAnimation/TomAndJerryTheMovie'' for some reason, is the same height as a human.
* ''VillageOfTheGiants'' briefly has a giant cat as the result of the growth formula experiments.
[[/folder]]

[[folder:Literature]]
* Literature/TheCatInTheHat is a six feet tall housecat.
* Llyan, from Lloyd Alexander's ''Literature/ChroniclesOfPrydain''. Fflewddur tames her with his harp and rides her in lieu of a horse.
* Anne Bishop's ''BlackJewels'' trilogy features plenty of [[TalkingAnimal intelligent, telepathic animals]]. The most impressive of them is Kaelas, an Arcerian cat, described as "eight hundred pounds of feline fury".
* Although it's never specified in Bulgakov's ''TheMasterAndMargarita'' how big Begemot/Behemoth is, Vladimir Bortko's TV adaptation of the novel portrays him as really huge, the height of a small human when standing.
* ''Literature/TheDresdenFiles'': Harry Dresden's cat Mister is easily 30 pounds and is described by Harry as being possibly part-bobcat.
-->"He's huge! What do you feed him?"
-->"Sheep."
* ''Kat Kong'' is a children's book by Dav Pilkey featuring pictures of a "giant" cat running around a model city.
* ''Literature/TheBookOfLostTales'', the unfinished early draft of ''Literature/TheSilmarillion'', featured Tevildo, Lord of Cats. He was later replaced by [[Literature/TheLordOfTheRings Sauron]].
* Edgewood Dirk, the prism cat, in Terry Brooks's ''MagicKingdomOfLandover'' series.
* "F-lions", from ''WorldWarZ'' are feral felines descended from domestic housecats and/or wildcats, which grew almost to cougar size while surviving in the depopulated ruins of North America.
* Guenhwyvar, the animal companion of [[TheLegendOfDrizzt Drizzt Do'Urden]], may qualify as Mega Neko. She is described as being a six hundred pound panther. This would make her about the size of a large Siberian tiger.
* Bustopher Jones, described as the "stoutest of Cats" and a "twenty-five pounder" in ''Literature/OldPossumsBookOfPracticalCats''.
* Diesel of the "Cat in the Stacks" cozy mystery series is a 36-pound Maine Coon cat who is said to be about half the size of a full-grown Labrador and accompanies his owner everywhere on a leash. The small Mississippi town they live in are still adjusting to the sight of him. The kicker is that he's only three, meaning he could ''still be growing''.
* One of the stories from ScaryStoriesToTellInTheDark, called ''Wait Til Martin Comes'', featured three black cats. One of them is a normal-sized cat, the second is the size of a wolf, the third is the size of a tiger. [[spoiler: In the end, none of them are Martin, the story implies that Martin is the size of an elephant.]]
* The {{Redwall}} series features several felines. They're usually larger than the heroes, so in story context they might be MegaNeko, but keep in mind the heroes of Redwall are ''mice.''
* In [[EarthsChildren Clan of The Cave Bears]] sequel ''The Valley of Horses,'' Ayla rescues and raises a baby cave lion. The cave lions were larger than their modern counterparts to begin with, but [[FluffyTheTerrible Baby]] was supposedly gigantic even for his species; because Ayla always made sure he had enough food and was not menaced by other lions or the weather, he was able to grow to his full potential. He was described at his full size as being as tall in the shoulder as a horse, and considerably longer from head to tail.
* Firecats, the companions of certain Sun Priests in the ''HeraldsOfValdemar'' novels, are built like housecats (the book covers depict them as red-pointed Siamese) but stand as tall at the shoulder as a mastiff.
* ''Porterhouse Major'' is a children's book by Margaret J Baker concerning the cat Porterhouse who grows to gigantic size (and acquires sentience) as a result of his child owners performing a magic spell involving the skull of a giant.
[[/folder]]

[[folder: Live Action TV ]]
* The ''[[Series/StarTrekTheOriginalSeries Star Trek TOS]]'' episode "Catspaw" featured a SufficientlyAdvancedAlien who turned herself into a giant cat. Unfortunately, the drama was ruined by low budget special effects fail. The "giant" cat was very clearly just a regular house cat that was stuck in a box made to look like one of the hallways. It didn't help that we'd already seen her in regular-sized cat form - played by the same cat.
* ''Series/TheGoodies'' had Twinkle a.k.a "Kitten Kong".
* An episode of ''UncleMortysDubShack'' has giant kittens terrorizing the city, and are just too darn cute to do anything about.
* The enormous cat in a ''Series/MontyPythonsFlyingCircus'' animated segment which defeats the Killer Cars by walking on two legs. In a spectacular ReverseFunnyAneurysm, the cat looks very familiar to anyone who's spent time on certain {{Imageboard}}s. Yes, that's right: the Killer Cars were defeated by Longcat's Siamese cousin.
* The Smilodon Dopant in ''Series/KamenRiderDouble''. Unlike the other Dopants, who are human when untransformed, the Smilodon Dopant's true identity is a cat.
* Oversized black felines were featured on ''Monsterquest'', which concluded that the investigated sightings were either escaped pet leopards, jaguars returning to their historical range, or ordinary housecats mistaken for giants due to a lack of nearby objects to show perspective.
* Steve French in ''TrailerParkBoys''.
* In a parody of Franchise/SuperSentai's TransformingMecha tradition, the White Racer from Series/GekisouSentaiCarranger has Radiecar Robo, a car which transforms into a MegaNeko.
[[/folder]]

[[folder:Music]]
* The rather SurrealMusicVideo for {{MGMT}}'s [[http://youtube.com/watch?v=XVnRzEjpUmE "Time To Pretend"]] features a few MegaNeko, including one with a person ''riding'' it.
* A parody of "My Grandfather's Clock", "My Grandmother's Cat" tells of an overfed feline that grows to tiger-like proportions and attempts to eat its owner.
* Shonen Knife's album Genki Shock includes a song called Giant Kitty (though apart from the TitleDrop the lyrics suggest it's really normal sized).

* [[CallARabbitASmeerp Muaka]], the giant cyborg felines of ''{{Bionicle}}''
[[/folder]]

[[folder: Video Games ]]
* In ''EliteBeatAgents'', the Hollywood stage, "Makes No Difference", chronicles the making of the fictional action film ''Romancing Meowzilla''.
** ''[[OsuTatakaeOuendan Osu! Tatake! Ouendan! 2]]'' has a HumongousMecha, built by three guys in a warehouse, facing off against the giant cat monster Nyaragon. It doesn't ''have'' [[WidgetSeries to make sense]].
* The Catsaber in ''VideoGame/{{Disgaea 4| A Promise Unforgotten}}'' can become one if another monster fuses with it.
* ''FinalFantasyVII'': one of the combinations in Cait Sith's Slots Limit Break causes him to grow to enormous proportions.
* A subtle inversion can be found in the ''Anime/GhostSweeperMikami'' game, where one of the levels features the protagonist being shrunk to the size of an action figure, and forced to ride on a normal-sized (but relatively huge) calico.
** This is based in an episode of the anime, where Mikami is under a curse that progressively shrinks her. Only that she rides on ''Yokoshima'' instead, even using reins.
* Speaking of giant calicos, Nago from ''{{Kirby}}'s Dreamland 3'' and his subsequent game cameos count as well. He's unique from Kirby's other [[PowerupMount Animal Helpers]] in that he essentially ''rides you'' by rolling you into a ball. It gets bizarre once you have the Parasol power equipped...
* In ''SuperPaperMario'', [[{{Otaku}} Francis]] has two gigantic ROBOT cats called [=BigMeows=].
* ''GrimFandango'' features cats roughly the size of horses that are used in greyhound-style races.
* One of the enemies in ''VideoGame/MegaMan3'' is a robotic cat several times Mega Man's size.
* The boss Andre in ''ShadowHearts: Covenant'' is a cat that stands taller than any of the party members, leading to Yuri saying one of the [[CrowningMomentOfFunny funniest lines ever]]:
-->'''Yuri:''' ''"That... is one giant pussy."''
* Mao from ''ShadowHearts: From the New World'' is also a giant talking cat, but she's on ''your'' side, despite being a gangster capo DrunkenMaster under Al Capone.
* ''[[SonicTheHedgehog Sonic Adventure]]'' introduces us to a character actually named "Big the Cat."
* Persian, Espeon, Delcatty, Liepard, and a whole bunch of other leopard-sized kitties from ''{{Pokemon}}''.
* ''DarkSouls'' features a large talking cat (roughly the size of a grizzly bear) named Alvina, who is also one of the game's covenant leaders. The game also features enemies called Great Felines, who are a fair bit bigger than Alvina.

* [[spoiler: Otilia]] in ''Webcomic/GirlGenius'' eventually comes to inhabit the body of a giant, mechanical cat. [[http://www.girlgeniusonline.com/comic.php?date=20101213 Here]] is her appraisal of it.
* In the old {{Cat Nine}}, [[http://radstylix.deviantart.com/art/Myan-s-Dream-159248898 this is supposedly what Myan was dreaming about]].

[[folder:Web Original]]
* [[LOLCats Longcat]] is [[OverlyLongGag looooooooooooooooooooooooooooooooong]]!
** And Tacgnol, Longcat's [[DarkIsEvil Color Swapped]] EvilTwin.
* And then there is Longcat vs Tacgnol- The Movie: [[http://www.allbenchmark.com/video Catzilla]].
* "Second Wind". A man and a giant cat end up in a story about life & death http://www.youtube.com/watch?v=erUMp1WZ6l4&feature=related
* Ambassador Rythax of the WhateleyUniverse. When Gateway first summons him, he's like a black panther the size of a tiger. With wings. He can be other sizes.
* LoadingReadyRun: Baxter, Graham's (and Kathleen's) pet Maine Coon. Not only is he enormous, but he has enough tail for three cats his size, and he's not yet fully grown! As frequently mentioned by the LRR-Crew, Baxter is a [[DungeonsAndDragons 'Dire Housecat']]. [[http://seenive.com/v/1040782417276919808 Witness his majesty.]]
[[/folder]]

[[folder:Western Animation]]
* In at least one episode of ''GarfieldAndFriends'', Garfield becomes super-sized in an AttackOfThe50FootWhatever plotline. (Some would argue that ''normal'' Garfield is a MegaNeko already.)
** The regular comics already played on this. One comic cover shows him blotting out the sun, and in one long cartoon, he dreams he becomes large enough to [[PlanetEater eat Saturnus]]!
* The ''CaptainStar'' episode "Waiting for Sputnik" features a cat that grows so big it endangers the planet.
* ''WesternAnimation/MakingFiends'': Both the web series and television series feature a ginormous red cat as one of the titular "fiends".
* One of the costars in [[http://www.youtube.com/watch?v=FcOz-uC4R4k this short]]. The giant kitty is both adorable and [[BadAss terrifying]] when appropriate.
* In Tex Avery's classic ''WesternAnimation/KingSizeCanary'', the same growth formula which creates the title bird is also consumed by the cat who fed the formula to the canary; he is planet-sized by the end of the cartoon.
* Super Kitty in the FairlyOddParents.
* Fat Cat from ''WesternAnimation/ChipNDaleRescueRangers'' towers over his cat henchmen, as well as the other feline characters.
* On the ''Series/MonstersVsAliens'' series, a kitten gets infused with some of Ginormica's quantonium, turning it into "Ginormicat".

[[folder:Real Life]]
* While not as huge as some of the fictional examples, [[http://www.youtube.com/watch?v=9SZEPNYHMKQ Savannah Cats]] are pretty big as far as pet cats go.
* The Maine Coon breed is generally considered to be the largest domestic cat breed, with some weighing in at over 25 pounds and 4 feet in length. See [[http://www.snopes.com/photos/animals/bigcat2.asp here]] for a picture of one large-looking specimen.
** Most housecats stop growing at about a year old. Maine Coons don't stop growing until then are about four years old. The kitty in that picture was only about two.
* Ligers are so huge that they are even taller than humans when they stand up. [[http://www.maniacworld.com/liger.jpg This pic speaks it.]]
