The life of the Masai revolves around cattle. Virtually all social roles and status derive from the relationship of individuals to their cattle. Cow's milk, together with blood, is the staple food of the Masai who eat no fruit or grain. Once a month, blood is taken from living animals by shooting a small arrow into the neck. This blood is then mixed with milk in a gourd which has been washed with urine to prevent spoilage.
