A lioness in oestrus is closely followed by the males of the pride. When the female is ready to mate, an indication is given by her making advances to the male of her choice. Copulation is quick and noisy. After some 10 to 20 minutes, mating is repeated. This routine can continue unabated, day and night, for several days. The mating pair are reluctant to go off hunting with the other pride and usually remain behind. Interestingly, a pride will generally accept an outside lioness that is on heat!
