Induced ovulation is a reproductive adaptation shared mostly by members of the Mustelidae, Leporidae, Felidae, and Camelidae families. Whereas female humans and other mammals that exhibit spontaneous ovulation have predictable cycles of fertility and non-fertility, induced ovulators only become fertile in response to sexual stimulation. While this arrangement may seem beneficial, some species take this strategy to an extreme.

Female ferrets, for example, enter into estrus at around 6 months of age and stay in estrus until they engage in copulation. Essentially, this means that once they start their period, it doesn’t stop until they get laid. Keeping in mind that prolonged estrus can result in anemia, immunodeficiency, and even death, females are under a lot of pressure to a hook up.
