Lions in mating season. Both sexes are polygamous and breed throughout the year, but females are usually restricted to the one or two adult males of their pride. In the wild, they usually breed no more than once in two years, and do not bother to hunt during the mating period. Females are receptive to mating for three or four days within a widely variable reproductive cycle. During this time a pair generally mates every 20–30 minutes, with up to 50 copulations per 24 hours. The gestation period is about 108 days, and the litter size varies from one to six cubs, two to four being usual.
