The gray wolf (Latin: Canis lupus) also known as the timber wolf, or western wolf, is a canid native to the wilderness and remote areas of North America, Eurasia, and northern, eastern and western Africa. While the gray wolf primarily feeds on medium to large sized ungulates, they are not fussy eaters and smaller sized animals may supplement their diet. Cannibalism is not uncommon in wolves; during harsh winters, packs often attack weak or injured wolves, and may eat the bodies of dead pack members. Wolves supplement their diet with fruit and vegetables. Digestion only takes a few hours, thus wolves can feed several times in one day, making quick use of large quantities of meat.
