Lions sleep up to 20 hours a day. They spend the remainder of their time hunting, socializing, mating and grooming. They are most likely to be active in the late afternoon and at night.
Lions spend most of their waking hours looking for food. An adult lion needs between 11 and 15 pounds of meat daily. Lions are predatory carnivores. Those that hunt as part of a pride are more successful than those that hunt as individuals. Also, lions may scavenge for food, rob other predators of food or eat animals that have died of disease. Adult lions have no natural predators.
