● A land animal is kosher if it has spilt hooves and chews its cud. It must have both kosher signs. Examples: cows, sheep, goats and deer are kosher, while pigs, rabbits, squirrels, bears, dogs, cats, camels and horses are not.
● Fowl: The Torah lists 24 non-kosher bird species -- basically all predatory and scavenger birds. Examples of kosher birds are the domestic species of chickens, ducks, geese, turkeys and pigeons.
● Fish & Seafood: A water creature is kosher only if it has fins and scales. Examples: salmon, tuna, pike, flounder, carp and herring are kosher, while catfish, sturgeon, swordfish, lobster, shellfish, crabs and all water mammals are not.
● All reptiles, amphibians, worms and insects -- with the exception of four types of locust -- are not kosher animals.
