Lions are the only cats that are social rather than solitary. They usually live in groups called prides, which vary in composition but may occasionally include as many as 30 individuals. The lionesses do a considerable part of the hunting. There is no definite breeding season. They inhabit grasslands, scrubland, and semidesert areas, where they hunt antelope, zebra, and other large herbivorous animals, as well as domestic stock. Lions ... eat carrion.
