Your morning adorable: Siberian tiger cubs at the Leipzig Zoo
These Siberian tiger cubs were born at Germany's Leipzig Zoo on March 2.
Siberian tigers (also called Amur tigers) are native to eastern Russia and parts of China and North Korea, where their wild population is thought to number only about 400 to 500 animals.
There were once eight tiger subspecies; three (the Caspian tiger, Javan tiger and Bali tiger) became extinct during the 20th century. The remaining five are all considered endangered; the rarest of these, the South China tiger, hasn't been spotted in the wild in more than 25 years. There are thought to be fewer than 20 South China tigers left in the world.
The Siberian tiger is the largest of the tiger subspecies. These little guys will stay with their mother until they're 2 or 3 years old.
