Males may follow a female. Eventually fighting for reproductive rights can take place (Nowak, 1997).
Depending on the region, leopards may mate all year round (India and Africa) or seasonally during January to February (Manchuria and Siberia). The estrous cycle lasts about 46 days and the female usually isin heat for 6-7 days. Cubs are usually born in a litter of 2-3, but infant mortality is high and mothers are not commonly seen with more than 1-2 cubs. The pregnant females find a cave, crevice among boulders, hollow tree, or thicket to give birth and make a den. Cubs open their eyes after a period of 10 days. The fur of the young tends to be longer and thicker than that of adults. Their pelage is also more gray in color with less defined spots. Around 3 months the infants begin to follow the mother out on hunts. At one year of age leopard young can probably fend for themselves but they remain with the mother for 18-24 months (Nowak, 1997, Guggisberg, 1975).
The females of this species tend to take care of the young but there have been reports of males helping the nursing mother and child, by bringing them kills for example (Guggisberg, 1975).
