Tigers eat a variety of prey ranging in size from termites to elephant calves. However, an integral component of their diet are large-bodied prey weighing about 20 kg (45 lb) or larger such as moose, deer species, pigs, cows, horses, buffalos and goats. Occasionally they may consume tapirs, elephant and rhinoceros calves, bear species, leopards and Asiatic wild dogs.

Tigers may consume up to 40 kg (88 pounds) of meat at one time.

It is estimated that every tiger consumes about 50 deer-sized animals each year, about one per week.
