Kosher animals

Kosher animals are those that comply with the regulations of Jewish dietary law and are considered fit to eat. These food regulations ultimately derive from various passages in the Torah with various modifications, additions and clarifications added to these rules by traditional Jewish law.

Leviticus 11:3-8 and Deuteronomy 14:4-8 both give the same general set of rules for identifying which land animals (Hebrew: בהמות Behemoth) are ritually clean. According to these, anything that "chews the cud" and has a completely split hoof is ritually clean, but those animals that only chew the cud or only have cloven hooves are unclean.

Both documents explicitly list four animals as being ritually impure:

Camels are actually both even-toed ungulates and ruminants, although their feet aren't hooves at all, instead being two toes with a pad. Similarly, although the bible portrays them as ruminants, the hyrax, hare, and coney, are all coprophages, and do not ruminate and lack a rumen. These obvious discrepancies, and the question of whether there is a way to resolve them, have been investigated by various authors, most recently by Rabbi Natan Slifkin, in a book, entitled The Camel, the Hare, and the Hyrax.

Unlike Leviticus 11:3-8, Deuteronomy 14:4-8 also explicitly names 10 animals considered ritually clean:

The Deuteronomic passages mention no further land beasts as being clean or unclean, seemingly suggesting that the status of the remaining land beasts can be extrapolated from the given rules. By contrast, the Levitical rules later go on to add that all quadrupeds with paws should be considered ritually unclean, something not explicitly stated by the Deuteronomic passages; the only quadrupeds with paws are the carnivorans (dogs, wolves, cats, lions, hyenas, bears, etc.), and all carnivorans fall under this description.
