Wild tigers can eat as much as 40 pounds of meat at one time. After eating a lot, they often do not eat again for several days. Over much of the tiger's broad geographic range, wild pig, wild cattle and several species of deer are its major prey. Unlike wild tigers which kill their prey and then gorge, tigers that live in zoos eat a prepared diet of horse meat and vitamins daily. They may eat as much as 10 pounds of meat per day.
