Tigers, the largest of the Asian big cats, hunt primarily through sight and sound rather than smell. They usually hunt alone and stalk their prey. A tiger can eat more than 80 pounds of meat in one sitting. Every two years, tigers give birth to two to four cubs.Tigers typically achieve independence at around two years of age and sexual maturity at three or four years for females and four or five years for males. However, juvenile mortality is high—roughly half of all cubs die before reaching the age of two.
