A baby lion is called a cub. A mother is a lioness, and a father a lion. All live in a social group called a pride, which consists of about 25 members.
After 100 to 119 days of gestation, litters of two to four cubs are born. The cubs are blind for three to four weeks and are born covered with light, spotted fur. Several factors contribute to high cub mortality, including extremely painful teething and starvation, because once the cubs are weaned, they feed last. Cubs begin to hunt with adults at one year, and they are sexually mature at age two.
