The Siberian tiger is a nocturnal hunter and will not share its range with other tigers. It will use its teeth, like its ancestor the saber-toothed cat, as a vital tool in hunting. When the tiger makes a kill, it will store leftover prey under brush or bury it under loose leaves until it can return to feed again. Males will leave all the cub rearing to the females. A Siberian cub is ready to hunt on its own at 18 months but will stay with its mother for two to three years.
