The Big Cat

Siberian tigers are the largest cats in the world. They live primarily in eastern Russia's birch forests, though some exist in China and North Korea. There are an estimated 400 to 500 siberian tigers living in the wild. The recent studies suggest that these numbers are stable.

Tigers live alone and aggressively scent-mark large territories to keep their rivals away. They are powerful hunters that travel many miles to find prey, such as elk and wild boar, on coats as camouflage and hunt by stealth. No two have exactly the same stripes. They lie in wait and creep close enough to attack their victims with a quick spring and a fatal pounce. A hungry tiger can eat as much as 60 pounds (27.2 kilograms) in one night.

Females give birth to litters of two to six cubs, which they raise with little or no help from the male. cubs cannot hunt untill they are 18 months old. They are remain with their mothers for two or three years, when they disperse to find their own territory.
