* Being a CatGirl Nekomata, Koneko of ''Literature/HighSchoolDXD'' can go into this.

* ''Fanfic/TriptychContinuum'': In ''[[Recap/TriptychContinuumCutieMarkCrusadersAlphaPackLeader Cutie Mark Crusaders Alpha Pack Leader]]'', Apple Bloom winds up with just about every male dog (of a certain age) in Ponyville following her -- because unknown to her, Winona is in heat and AB's picked up the scent. They're waiting for her to lead them back to the border collie. ''She'' decides she may be on the verge of manifesting a mark for [[WrongAssumption canine training]]. Dogsledding ensues. Using a "borrowed" sleigh. On grass. [[DisasterDominoes In the summer.]]

[[note]]Some are apparently infertile and never go into heat, although it can be faked, albeit with some difficulty.[[/note]] Those that do emit pheromones that attract the attention of every man in the vicinity.

* It's briefly mentioned in ''Literature/TailchasersSong'' that Roofshadow avoids males during heat in order to stop herself from having a litter she doesn't want yet.

* In ''Literature/WorldWar'', [[LizardFolk the Race]] has a specific mating season, meaning they're [[HumansThroughAlienEyes disgusted by humans]] being "in season" ''constantly''. But when their females arrive on Earth, it's discovered that [[AlienCatnip ginger]], which is an addictive narcotic to males of the Race, causes females to go into heat immediately. This results in mass chaos from MakingLoveInAllTheWrongPlaces and introduces TheOldestProfession to their species, but also the previously-alien concept of monogamous relationships.

*** In the ''Series/StarTrekTheNextGeneration'' episode "[[Recap/StarTrekTheNextGenerationS2E19Manhunt Manhunt]]", Lwaxana Troi is going through the Betazoid equivalent of menopause (called "The Phase"), which causes a tremendous increase in her sex drive. She tries to mate with Captain Picard and get married to Commander Riker.
*** In the ''Series/StarTrekDeepSpaceNine'' episode "[[Recap/StarTrekDeepSpaceNineS03E10Fascination Fascination]]", Lwaxana suffers from what's basically empathic incontinence -- she inadvertently broadcasts her emotions to other people, [[LoveIsInTheAir causing various members of the cast to suddenly experience strong lustful urges toward people they're already attracted to]]. If they're with someone who has similar feelings for them, the results are merely unprofessional and embarrassing. If they're with someone with someone who ''isn't'' attracted to them, things get much worse. Chief O'Brien nearly attacks Quark after the latter sexually harasses Keiko.

* Older ''TabletopGame/DungeonsAndDragons'' monster manuals that go into detail about creature ecology sometimes mention this. For example, the world of [[Literature/{{Dragonlance}} Krynn]] has hatori, giant [[SandIsWater sand-swimming]] [[NeverSmileAtACrocodile crocodiles]], which are dangerous enough in normal circumstances, but every ten years congregate in the heart of the desert, where the males fight vicious battles over breeding rights.

* Subverted in ''Webcomic/{{Freefall}}'': Florence, an {{Uplifted|Animal}} wolf, has an estrus cycle, but when her human boyfriend's mother asks what it's like to be in heat she [[http://freefall.purrsia.com/ff3500/fc03487.htm turns it around]] and suggests that since humans constantly produce sex hormones a better question might be "what is it like '''not''' to be in heat?"
* In ''Webcomic/KevinAndKell'', [[ExplosiveBreeder all the rabbits enter a mating frenzy every March]], referencing the March Hare. Kevin's friskiness during that time is sometimes the subject of the strips.

* In the furry comic ''Webcomic/{{SSDD}}'' Annie, as an anthropomorphic red fox, goes into heat [[http://www.poisonedminds.com/d/20000131.html once a year]]. It starts out as her acting even hornier than normal but then turns into a massive case of PMS.

* ''WesternAnimation/StarVsTheForcesOfEvil'': Mewman females such as Star go through a process known as "Mewberty." It starts with them shedding little hearts whenever they're around attractive boys and ends with them transforming into a six-armed butterfly monster that captures and cocoons every male it comes across. Unfortunately despite how horrifying the whole event is for everyone involved, there's nothing you can do other than letting it run its course. After Star's Mewberty, she has tiny wings that she can barely use to flutter, and her mother later demonstrates the ability to go into six-armed butterfly mode at will.
