Dietary Habits

Tigers, regardless of their subspecies, are carnivorous animals. This means that they eat meat and will not ordinarily consider any sort of vegetation to be part of their diet. In order to eat, the tiger must hunt for its prey; a process that is taught to the cubs by the mother when they are only a few months old to train them for survival on their own

Diet
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. In cases where food is not available or for the purposes of easing digestion, the tiger will eat berries, grasses and different types of fruit.

Method of Feeding
Tigers mainly rely on their sense of sight and hearing rather than on smell when hunting prey. They cautiously stalk their prey from the rear in attempt to get as close as possible to their unsuspecting prey. Then they attempt to take down their prey with a powerful bite to the neck and/ or throat.
