A Kosher animal
Kosher Animals by Category
Only those with cloven hoof and that chew their cuds, such as oxen, sheep, goats, deer, gazelles, roebuck, wild goats, ibex, antelopes, and mountain sheep. Pigs — the best-known non-kosher mammal — are not kosher because they do not chew their cuds.

Jews observing kashruth may eat only those fish that have both fins and scales (i.e., not shellfish), certain birds, and mammals that chew the cud and have cloven feet. These mammals and birds must be slaughtered according to a ritual that, if violated, makes the meat “unfit” for use. Food ritually unfit, for whatever reason, is called “forbidden” (terefah), the opposite of kosher (“fit,” or “proper”). Because animal blood may not be eaten, meat must undergo a ritual process of presoaking and “salting” (meliḥa) to draw off any blood that may remain within the meat after the ritual slaughter (shehitah).
