A symptom of a SuperDeformed ArtShift, where occasionally a character will sprout UnusualEars or other animal features (paws, tails, etc.) during certain moments to accentuate certain aspects of their personality. What ears symbolize what varies from culture to culture, but generally they break down into three groups:

* '''Cats''': {{Genki| Girl}}ness, excitability, occasionally irritation. Usually accompanied by a CatSmile.
* '''Dogs''': Hyperness, clumsiness, affection. Generally done to a character who is loving, but [[{{Cloudcuckoolander}} not all there in the head]].
* '''Foxes''': Mischief, wisdom, slyness. May be either friendly or malevolent.

Other variants usually depend on the character and whatever is associated with them. If the character can actually ''transform into'' said animal it can sometimes be a clue of their true nature, though usually this is played for comedy and not meant to be taken seriously.

[[folder: Anime And Manga ]]

* Mimi and Kuro have been known to sprout bunny and cat ears, respectively, in ''Kodomo No Jikan''. With Kuro, it can be hard to tell if it's a case of HyperspaceEars or not, since she does occasionally wear a cat ear accessory.
* In ''Manga/RurouniKenshin'', Megumi's NoblewomansLaugh is occasionally accompanied by growing fox ears. Her nickname on the show itself is "Kitsune-onna" (literally "Fox Woman") or "Vixen" in the English version.
* The cursed characters in ''Manga/FruitsBasket'' sometimes take on characteristics of their animal selves in comedic situations:
** Kisa, the tiger-girl from, pops out her ears and tail at one point, when she perked up at hearing Tohru (her surrogate mother) come home.
** Kyo the cat will sometimes visibly bristle ears and tail up when angered, or flatten his ears when embarrassed.
* Hayama in ''Manga/KodomoNoOmocha'' occasionally sprouts leopard ears and tail when acting especially cool.
** And once, after Sana outright asks him to kiss her, he sprouts mouse ears, a mouse nose, and whiskers. Sana remarks in amazement that she didn't know "you could do mouse, too! I thought you only did leopard."
* Tamaki (who's basically a GenkiGirl in a {{bishonen}}'s body) does this with puppy ears once in a while in ''Manga/OuranHighSchoolHostClub''.
* Happens a few times with Hazuki in the first part of ''Tsukuyomi'', before she gets into the habit of wearing a CatEaredHeadband. This was initially intended to be only an occasional gimmick, sometimes done with headbands and other times with this trope, until the Anime made it a central aspect of the entire design, and then went on to add cat ears to everything, with absolutely no exceptions.
* In the ''Manga/DescendantsOfDarkness'' anime series, Tsuzuki gets dog ears and a tail a few times when acting especially {{keet}}ish. This has apparently lead some fans to think he can actually turn into a dog if they don't get the visual metaphor.
* Ichigo literally has her kitty features (ears and occasionally a tail) pop up when she gets excited or nervous in ''Manga/TokyoMewMew''. Later on, it accelerates to actually becoming an adorable kitten. Unlike others, this is actually canon, and a plot point, and also leads to a lot of awkward scenes of her having to stick her head in bushes or suddenly having to find a quick way to hide them.
* Yuzuriha in ''Manga/{{X1999}}'' (especially when trying to cheer Kamui up) has pointy dog ears because her spirit animal is a dog.
** And in one of Creator/{{CLAMP}}'s earlier works, ''Manga/MagicKnightRayearth'', Hikaru would sometimes get cat ears. Her figma even came with cat ear parts!
** You know what, Creator/{{CLAMP}} in general. ''Manga/{{Suki|ALikeStory}}'' has the main character sprout dog ears and tail almost every chapter.
* Shuuichi from ''Manga/{{Gravitation}}'' occasionally sprouts them, and at one point turns totally into a cat for comedic effect.
* Yuriko Oozura from ''Anime/MaoChan''. In the manga, she also has a Sprouting Tail.
* ''Manga/AiYoriAoshi'': Aoi sprouts nekomimi (and a tail) when she's rolling around in Kaoru's bed.
* ''Manga/HidamariSketch'': As a one-time thing, [[http://img81.imageshack.us/i/hidag.jpg/ Sae sprouts cat ears and tail]] purely out of surprise/confusion when Yuno's dad angrily points at her and shouts "[[YouExclamation It's YOU!]]" as she walks in. (He mistook her as Yuno's boyfriend based on a stray hair he found in Yuno's room.)
* Lately in the ''Manga/MahouSenseiNegima'' manga, a number of the students use magic to sprout animal ears and/or tails in order to not be recognized on wanted posters. The sad thing is that it ''[[ClarkKenting works]]''.
** Sort of inverted with Kotaro. He ''really has'' dog ears which he is somehow able to hide in his hair.
* Hayate of ''Franchise/MagicalGirlLyricalNanoha'' had tanuki ears (and sometimes tail) pop up every so often during the ''[=StrikerS=]'' [[ComicBookAdaptation manga]] when she's feeling mischievous.
* All the Hounds in ''Petit-Hound'' have this, and no, it's not for comedic purpose.
* Liza Wildman of ''Manga/PrincessResurrection'', is half werewolf. Besides her transforming forearms, her only wolf-like feature are her wolf ears that only pop up when she is embarrassed/annoyed, or listening intently.
* Ikeda Kana from ''Manga/{{Saki}}'' sprouts two cat ears whenever she has [[LesYay intimate interaction]] with Mihoko, complete with purring.
* In ''Manga/HayateTheCombatButler'', when burgers are mentioned around [[spoiler:Machina]], he sprouts what are likely dog ears and tail.
** When his master praises him or he's contemplating something ''trickstery'', he gains fox/tanuki ears and a tail. [[spoiler:And his alternate form is that of a giant snake.]]
** Hayate was trying to conceal an involuntary change in his appearance, and told [[GenkiGirl Izumi]] that [[SuspiciouslySpecificDenial he had nothing to hide]]. (Probably) fox ears popped up and she began trying to pull away the cloak he was wearing.
* ''Manga/{{Nana}}'' has Nana K sprouting dog ears with some regularity. It's part of the [[UsefulNotes/{{Hachiko}} origin]] behind her nickname Hachi.
* This occurs to a large amount of various characters in ''Manga/AliceAcademy''. It's more prevalent in the manga than in the anime.
* ''Manga/KatekyoHitmanReborn'': Whenever Gokudera's really happy (usually because of praise from Tsuna) he [[http://media.photobucket.com/image/gokudera/Akatsuki-Chika/Katekyo%20Hitman%20Reborn/Gokudera_puppy.jpg?o=224 grows doggy ears and a tail]].
* In ''Manga/HunterXHunter'' Killua does this at least twice in the anime.
* [[ThatOneGuy Hiroki]] [[ButtMonkey Komachi]] from ''ChuBra'' grows cat ears and tail whenever he's nervous, which is the result from being surrounded by [[AllergicToLove girls]] [[AccidentalPervert who deal with underwear on daily basis.]]
* Tsubasa Hanekawa of ''LightNovel/{{Bakemonogatari}}'' develops feline characteristics after being possessed by a 'meddlesome cat' who would take control after an accumulation of severe stress.
* Maron/Jeanne does this several times in the ''Manga/KamikazeKaitouJeanne'' manga. Usually when thinking of Kaitou Sinbad.
* Tsumiki in ''Manga/PlaceToPlace''.
* Kyoko from ''Manga/SangatsuNoLion'' sprouts cat ears to show her excitability and affection toward Gotou.
* In ''Manga/KotouraSan'', from [[DirtyMindReading Haruka's point of view]] at least, Manabe's entire head often goes into werewolf-mode when he's feeling lustful.
* It occasionally happens to Yurine in ''Manga/AnoKoNiKisuToShirayuriWo'', especially when she is with [[SingleTargetSexuality the girl she loves]], Ayaka.
* Played with in ''Manga/NabariNoOu''; when he's feeling mischievous, protagonist Miharu Rokujou frequently sprouts little devil wings and a tail. No ears, though.

[[folder: Video Games ]]

* Though it doesn't happen in the finished game, the [[http://pics.livejournal.com/nunuu/pic/0021hfqk/g33 storyboards]] for ''VideoGame/FinalFantasyVII Crisis Core'' show Zack sprouting dog ears and a tail to fit his nickname of "Puppy".


[[folder: Visual Novels ]]

* From ''[[VisualNovel/{{Tsukihime}} Kagetsu Tohya]]'', Len -- the {{Really Seven Hundred Years Old}} {{Elegant Gothic Lolita}} semi-[[HornyDevils Horny Devil]] -- is half cat, and thus would occasionally add CatGirl to the list when surprised enough [[http://static.tvtropes.org/pmwiki/pub/images/ear_today_gone_tomorrow.gif to pop out her fuzzy ears]].
* In ''VisualNovel/LittleBusters'', Rin's angry sprite includes cat ears, while Kud's upset/hurt/flustered sprite has her with dog's ears and a tail.
* In ''VisualNovel/MajiDeWatashiNiKoishinasai!'' Kazuko often sprouts dog ears when happy or depressed.


[[folder: Webcomics ]]

* Morgan [=McKnight=], from ''Manga/AoiHouse'', tends to grow cat ears, as befitting her GenkiGirl personality.


[[folder: Western Animation ]]

* In a 1930s ''WesternAnimation/{{Popeye}}'' cartoon, a Creator/MaeWest expy is brazenly flirting with Popeye and smacking around Olive Oyl, who finally downs a can of spinach and momentarily sprouts cat ears while [[DesignatedGirlFight yowling and hissing!]]
* In the WesternAnimation/BugsBunny short "The Hare-Brained Hypnotist", after Elmer learns to perform a HypnoticGaze and tries it on Bugs, Bugs reverses the hypnosis and mind-controls Elmer into acting like a rabbit. Elmer's ears briefly grow into rabbit-like ears to set up a [[SwappedRoles role-reversal]] scene.
