From morning till night, the warthog moves in search of food. Its diet consists of herbs, fruits, soft barks, roots, and bulbs. It uses its muzzle and tusks to dig some of its food, and it is often seen kneeling down while eating. Geophagous and osteophagous, it may chew soil and bones to supplement nutrients. The piglets also eat their parents' feces to strengthen their digestive system with useful bacteria.
