There's a problem that arises in stories featuring reasonably anthropomorphic animals, both of the plain old [[TalkingAnimal talking]] and [[FunnyAnimal funny]] varieties. Many writers want to include romantic plots or subplots in these works. For human characters, [[TrueLovesKiss a kiss]] often serves as [[SealedWithAKiss the closure]] to a WillTheyOrWontThey arc.

The problem arises from the fact that, unless you're writing [[EverythingsBetterWithMonkeys monkeys and apes]] (or fish, we suppose, but there are usually NoCartoonFish) most animals just ''don't have the facial structure required'' for a human-type, lip-to-lip kiss. So having animals "kiss" like humans isn't necessarily plausible. So what do writers do?

Well, usually one of two things:

* '''Ignore it.''' Anatomy? What anatomy? For the purposes of the work, a duck's bill can become just as pliant and squishy as human lips so that [[WesternAnimation/DonaldDuck Donald and Daisy]] can have their smooch. {{Funny Animal}}s, or just those in less-realistic works, tend to get saddled with this option.
* '''Come up with an alternate gesture with the same meaning.''' After all, real-world animals ''do'' have ways to express affection, so why not? Common choices for this one include: Licking (like [[AllAnimalsAreDogs dogs]]), rubbing noses/snouts, [[HeadbuttOfLove bumping foreheads]], or crossing necks (which can also substitute for a hug). Works with {{Talking Animal}}s, or more realism, tend to use this. Alternatively, it might just be more whimsical.

[[folder: Comics ]]

* [[ComicBook/DisneyDucksComicUniverse Donald Duck]], as well as many of the [=McDuck=] clan as writ by Creator/DonRosa. Birds deserve to kiss, too!

[[/folder]]

[[folder: Western Animation ]]

* In ''TheSwanPrincess,'' Lt. [[SpeciesSurname Puffin]] manages to give a kiss to the back of Odette's hand. The tip of his beak kind of... folds back.
* ''WesternAnimation/ChickenRun'' makes heavy use of the AlmostKiss because the animators weren't sure how to animate chickens kissing. The kiss at the end is staged so that the beaks are hidden from view.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has actually shown both variants of the trope. Spike fantasizes about kissing Rarity in "A Dog and Pony Show" and is kissed on the cheek twice by Rarity in "Secret of my Excess". Also, at the end of "Canterlot Wedding", Cadence and Shining Armor are shown kissing in the usual way.
* Two pigeons that show up in the ''WesternAnimation/{{Futurama}}'' movie, ''The Beast With a Billion Backs'' French kiss. Interestingly, the two pigeons are otherwise normal pigeons and their beaks don't get as pliant and squishy as human lips.
* ''{{Rio}}'' has its two main birds kiss despite the movie having a surprising amount biological correctness up to that point.

!!Examples of Type 2:

[[folder: Anime and Manga ]]

* ''{{Catnapped}}!'' has CatGirl Chuchu impart a quick lick on the cheek to Yasuo [[SmoochOfVictory after]] [[PuppyLove he saves their world]]. JustInTime, no less.

[[folder: Comics ]]

* Oddly enough, in ''ElfQuest'', the obviously humanoid elves are never shown kissing, even though the comic has some rather explicit sex scenes. WordOfGod states that elves do not kiss.

[[/folder]]

[[folder: Film ]]

* In ''Film/{{Godzilla 2014}}'', the MUTO couple nuzzle each other and touch noses, making beeping noises as their eyes flash towards each other.

[[/folder]]

[[folder: Literature ]]

* In ''Literature/WarriorCats'' the cats often rub their faces together or wash each other as a sign of affection. Which is pretty much what cats do in RealLife, so it works pretty well.
* Literature/{{Dinoverse}}: Bertram and Canadayce, in the bodies of short-beaked dinosaurs, spontaneously try a kind of beak-locking gesture from which Canadayce can tell that Bertram's eaten peppermint. Although Bertram had a crush on Canadayce he didn't feel anything from the kiss - ''dinosaurs'', not surprising - and it's not until they're human again and she can kiss with lips that he's actually affected. In other books with beakless dinosaurs there is face-nuzzling. A dinosaur does this a lot with a girl in a dinosaur's body; when the dinosaur ends up SharingABody with another kid, this happens.
--> He leaned in close and brushed his lips with hers. The part of him that had once been an Acrocanthosaurus didn't understand this odd custom.
--> But it felt certain it could grow to like it.
* Not animals, but in the future world of the ''{{Xenogenesis}}'' series, humanity has been altered by aliens, and as a result adults feel extreme discomfort if they make skin-to-skin contact with one another. Because of this, stroking someone's hair has become the default gesture of affection.
* Also not animals, but there are a lot of lipless aliens in ''Literature/{{Animorphs}}''. Andalites kiss by stroking each other with their palms. Hork-Baijir kiss by touching their foreheads against each other.
* For the dragons of the Literature/AgeOfFire verse, a crossing necks is the equivalent of a kiss, while folding wings over another is a hug.
* The [[OurDragonsAreDifferent Kantri]] of Literature/TalesOfKolmar have rigid faceplates, but have affectionate gestures similar to the above dragons, as well as twining together and touching faceplates.
* ''Literature/RaptorRed'' has the titular raptor and her fellow raptor kin performing things such as neck presses, muzzle bumps, grooming, and leaning into each other as gestures of affection. This is meant to evoke comparisons with present-day birds, due to similar physiology and equally similar limitations of that same physiology (most notably, a lack of lips or mouth motions beyond open and close).

[[folder: Webcomics ]]

* In ''Webcomic/SandraAndWoo'', Woo and his LoveInterest Lily are portrayed [[http://www.sandraandwoo.com/2010/04/01/0151-spring-fever/ rubbing palms]]. Since raccoons' palms are supersensitive, [[WordOfGod the author]] thought it would be a neat alternative.

[[/folder]]

[[folder: Video Games ]]

* In ''VideoGame/MassEffect2'', kissing is a problem for female Shepard and her optional [[InterspeciesRomance alien Love Interest]] Garrus, as his species doesn't really have lips and swapping saliva could lead to a fatal allergic reaction for both of them. They settle for a HeadbuttOfLove instead. [[http://nicca-11y.deviantart.com/art/How-to-kiss-a-turian-II-254551631 Fanart has fun with this]].

[[folder: Western Animation ]]

* ''Disney/TheLionKing'' uses the "crossing necks" variant, for both romantic and familial affection.
** The sequel does, at a couple points, have Kovu and Kiara kiss like humans, both on the cheek and on the "lips."
* In ''WesternAnimation/{{WALL-E}}'', a robotic "kiss" is more like a static electrical shock.
* In the ''WesternAnimation/{{Animaniacs}}'' movie, ''Film/WakkosWish'', Yakko rubs noses with Dot. As above, it's a sign of familial affection.
* According to WordOfGod, ''WesternAnimation/{{Gargoyles}}'' stroke hair, horns and brow ridges rather than kiss. This can be seen between [[spoiler:Goliath and Demona]] in the 5-part series premiere, "Awakening."
** Angela and Broadway's kiss was explained as Angela being raised by humans and Broadway having seen a lot of movies. (Admittedly, that doesn't explain the flashback of Demona kissing the petrified Goliath goodbye before leaving Castle Wyvern in the ''City Of Stone'' arc.
** [[spoiler: Elisa and Goliath share a very human kiss]] at the end of season 2. Well, it was more like she kissed him and he was too surprised to really respond ... but that didn't stop him from having a very goofy grin on his face after.
** [[spoiler: Elisa and Goliath kiss again]] in issue 7 of the Slave Labor Graphics comic book. This time she strokes his hair first, then he picks up and kisses her.
* The horses in ''WesternAnimation/SpiritStallionOfTheCimarron'' mostly use nuzzling or neck-crossing. Spirit also gives Little Creek a "hug" by putting his head over Little Creek's shoulder near the end; real-life horses actually do this.
* The ponies on ''WesternAnimation/MyLittlePony'' comfort each other by nuzzling and licking.
** In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Hearts and Hooves Day", pony couples are shown performing Eskimo kisses.
* Belle and the Beast in Disney's ''Disney/BeautyAndTheBeast'' never kiss, but the Beast frequently runs his hand through Belle's hair. He also does this as a human prince before he and Belle have their first kiss, which seems to reassure an understandably floored Belle that he ''is'' the Beast.
* Lampshaded on ThePenguinsOfMadagascar in the episode "The Falcon and the Snow Job." After rescuing Kitka (the GirlOfTheWeek falcon), Skipper goes in for the big kiss, only to be interrupted by King Julien mocking them (and making pecking gestures with his hands):
-->"Mmm.. Peck Peck. Pecky, love peck.. (I'm trying to kiss but I got no lips)... Peck...No, wait! I'm getting good at this pecking."
** Though a frame by frame shows that the animators know how to animate CGI penguin kisses by when Private kisses the Peanut Butter Winky in "Skorca."
-->"Mmm.. Nutty!"
** Hans the Puffin in Huffin' and Puffin:
-->'''Hans:''' You should know I kissed your sister. On the lips!
-->'''Skipper:''' I don't have a sister. And if I did, she wouldn't have lips.
-->'''Hans:''' Then who did I kiss?
* ''{{Jimmy Two-Shoes}}'': Cerbee and Jasmine kiss by licking.

[[folder: Theater ]]

* The musical version ''Theatre/TheLionKing'' follows the movie's model by having the lion's hug and nuzzle, despite them being played by human actors able to kiss now.

[[/folder]]

[[folder: Real Life ]]

* Dog owners often refer to their dog licking a face as getting "kissed", more so for small breeds. Cats nuzzling their owners is also often said to be this.
** Though cats have scent glands in their muzzles, and this is at least partly them marking you as "their property." Bumping the top of their head against you is more akin to actual affection. The page image shows Nala doing this to Simba (she's also rubbing her muzzle on him, but it starts as more of a headbutt).
* Among sociable mammals, such as chimps, baboons, or rats, mutual grooming can serve a similar function to human kissing.
** In fact, the male Crab-eating Macaque will groom the female so she'll agree to mate.
* Puffins 'kiss' using a process called 'billing'. Basically, they rub both their beaks against each other in a way that is similar to kissing. Awwwwww.
* Inverted by 'kissing fish'. What looks like a kiss is acutally [[HoYay two males]] [[FoeYay fighting for dominance]] and the right to breed with local females.
