All tigers are carnivorous, and their diet consists mostly of animals weighing about 45 pounds or more. It is estimated that tigers kill about 50 deer-sized animals a year, or about one a week. Because they may not make another kill for days, tigers can eat up to 40 pounds of meat in one sitting.

Female tigers tend to stay in their own territory when hunting, while males may encroach upon the territory of other tigers. Tigers are solitary creatures and usually prefer to hunt alone. They are native to Asia and are mostly found in the swamps, grasslands and rain forests of Southeast Asia, China, Korea and Russia. The Bengal, Siberian, Sumatran, Malayan, Indochinese, South China tigers are the last six living species of tiger out of the previous nine living species of tiger. The diet of these six living species depends greatly on where they live and what foods are available. If food is scarce, tigers may resort to eating rodents, small birds or insects. Tigers more commonly eat sambar, chital, sika deer, nilgai, buffalo, gaur, monkeys, civets, porcupines, fish, frogs, crabs, monitor lizards and snakes. A tiger may attack a baby rhino or elephant if it happens to be vulnerable. They may also eat berries, grasses or different types of fruits when food is not available or to aid their digestion, though vegetation is not a normal part of their diet.
