Ruminants have chew their cud. All ruminants are two-toed (that is, if they have hooves, they are cloven). Cattle, sheep, goats, deer, ibex, mountain goats, bighorn sheep, and several other wild varieties. Camels and llamas have two toes, but they don't really have hooves in the sense of walking on their toenails the way hooved animals do; rather, their toenails resemble claws.
