Following mating, the gestation period for tigers is approximately 103 days. One usually dies at birth. They live on their mother's milk for 6-8 weeks before the female begins taking them to kills to feed. They begin making their own kills at about 18 months of age. Young tigers leave their mother's range at anywhere from a year and a half to three years of age, depending on whether the mother has another litter.
Females tend to stay closer to the mother's range than males.
