Litters consist of two or three cubs that weigh about 3 pounds each. Some mothers carefully nurture the young; others may neglect or abandon them, especially when food is scarce. Usually two or more females in a pride give birth about the same time. A lioness will permit cubs other than her own to suckle, sometimes enabling a neglected infant to survive. Capable hunters by 2 years of age, lions become fully grown between 5 and 6 years and normally live about 13 years. Lions have long been killed in rituals of bravery, as hunting trophies and for their medicinal and magical powers. Although lions are now protected in many parts of Africa, they were once considered to be stock-raiding vermin and were killed on sight. In some areas, livestock predation remains a severe problem. Early written records described the giraffe as "magnificent in appearance, bizarre in form, unique in gait, colossal in height and inoffensive in character."

Family members look out for one another; if one becomes separated from the rest, the others search for it. The group adjusts its traveling pace to accommodate the old and the weak. The females within a family observe a strict hierarchical system. A dominant mare always leads the group, while others follow her in single file, each with their foals directly behind them. The lowest- ranking mare is the last in line. Although the stallion is the dominant member of the family, he operates outside the system and has no special place in the line. Zebras are avid grazers. Both Burchell''s and Grevy''s zebras are in constant search of green pastures. In the dry season, they can live on coarse, dry grass only if they are within a short distance (usually no farther than 20 miles away) of water holes. Grevy''s zebras are now mainly restricted to parts of northern Kenya.
