Most lions have worms and are known for their high cub mortality rate. Lionesses begin reproducing at about 2.5 to 3 years of age. They reproduce once per year at any time of the year. A litter usually consists of 3 to 6 cubs after a gestation of 108 days. Cubs are weaned after about 3 months.
Some lions acquire the habit of eating people.
These animals must be killed promptly because they won't stop. Man-eaters can be old lions with worn down teeth or they can be lions in their prime. The lion has keen senses of hearing, smelling, and sight. Their night vision is extremely keen. The loud roar of the lion can be heard from the early evening throughout the night.
