A tiger's favourite prey is deer and wild boar.Depending on the habitat, tigers may also eat antelope, buffalo, domestic livestock, peafowl, monkeys, civets, porcupines,(ouch) fish, frogs, crabs, large monitor lizards, pythons, and young elephants or rhinos. Grass, fruits, and berries are also eaten.
Prey living in dense, forested areas (where tigers are found) tend to be more scattered in distribution. Because of this, tigers will attack most any animal that places itself in a vulnerable position. Tigers kill animals of all ages and physical conditions, including animals in their prime.
