* Being a CatGirl Nekomata, Koneko of ''LightNovel/HighSchoolDxD'' can go into this. However being also fairly under-developed puberty wise and small means that actually going through with it and getting pregnant would be ''very'' dangerous and thus she avoids actually going through with the instincts of heat.

* ''Fanfic/PreyMate'' starts when the half-demon Raven hits her second heat. She looks for someone to help with her heat and ends up attracted to Jinx, due to her magical abilities.

->As a young fela I scorned the young males in our tribe--they were overbold and self-satisfied. When I cams into my season I made sure to be far away from the clan, so I would not be betrayed by nature into bearing a litter that I did not yet desire. I found that I ''enjoyed'' being by myself; enjoyed the solitary way of the hunter.

This trope can also appear for animal or animal-like characters, ranging from {{Partially Civilized Animal}}s, PettingZooPeople, [[LittleBitBeastly humanoids with animal characteristics]], or aliens/monsters. In this case, heat is depicted as a more annoying version of menstruation. The trouble comes from the character's need to breed, as well as oftentimes heat itself being depicted as uncomfortably hot to experience. Mating season is prime humor potential because even normally mellow or sophisticated characters [[MyInstinctsAreShowing can't avoid their base instincts]].

* Male elephants go into a period called musth when they're ready to mate. The condition can be identified by what look like tear streaks on the head and dribbling urine. They're extremely dangerous and unpredictable during this time.

** In his first life, Toby lives in a compound with several other dogs. One day he notices that he's discovered a new "game" to play with his best friend, a female named Coco. She doesn't like it so much. Toby's annoyed that all the other males also want to play his new "game". As it turns out, Coco was in heat and all the males wanted to mount her. Coco, Toby, and a few other dogs are promptly neutered.

Another common joke is people in the wilderness during mating season. This usually leads to an animal attack due to the high-amount of animals in the area.

* ''Fanfic/TriptychContinuum'': In ''Recap.TriptychContinuumCutieMarkCrusadersAlphaPackLeader'', Apple Bloom attracts all the male dogs after her dog, Winona, has rubbed all over her while in heat.

** Vulcans experience ''pon farr'' every seven years, a hormonal imbalance that will kill them unless they mate or participate in a DuelToTheDeath.

Many animals have a mating season or an estrous cycle (referred as "going into heat"). Depending on the animal, this can be very messy, smelly, or (especially whsn it comes to males in rut) dangerous.
