The African Lions are the most social of the cats, with related females remaining together in prides, and both related and unrelated males forming coalitions. Gestation is about 100 to 120 days after which the lioness gives birth to a litter of 1 to 6 cubs, with the average being 2 or 3. The cubs weigh less than 5 pounds and their eyes open in about three weeks. After three months, cubs accompany their mother on hunting trips. They will stay near their mother for the first 2 years.
