Research overview: induced ovulation across carnivores compared with felids

Induced ovulation is widespread but not universal among carnivores, and comparing felids with mustelids, some canids, and other groups clarifies how the mechanism evolved and varies. This overview surveys patterns of induced versus spontaneous ovulation across carnivore lineages and considers ecological correlates such as solitary living, dispersed populations, and the need to ensure a mate is present before committing to ovulation. It discusses how facultative spontaneous ovulation appears in several taxa and how the strict induced model in cats is more nuanced than once thought. The comparative perspective helps explain felid reproductive physiology in evolutionary context and informs which model species best guide assisted-reproduction work for rare cats.
