A female tiger is called a tigress. Female tigers are smaller than their male counterparts, including the forepaws on their feet. A tiger's sex can be determined just from the pawprints that the tiger leaves behind.
Tigers are the largest members of the cat family. They typically live solitary lives within a territory that they mark as their own. Tigers of the same sex who intrude into another tiger's territory are likely to be met with hostility, especially females. A tigress lives with her cubs for about the first two years of their lives, until they can hunt for themselves. Then, they leave to look for territory of their own.
