Lions are members of the cat family. Lions live in groups called prides including up to 18 animals. There is usually one older male and the rest of the pride are females and cubs. Young males are sent away from the pride at about age 2. Lions spend much of the day lying about, but are active in the late afternoon. When the pride hunts, males drive the prey antelopes toward the hidden females who pounce on the prey and kill them. The pride protects its hunting territory from other prides. Lions give birth to litters of two to three cubs, which take about one and a half years to grow up.
