These cats are known for their orange and white fur with its black stripes. This pattern camouflages them in the tall grasses or forest undergrowth. Their diet consists of deer, pigs, antelope, buffalo and a variety of small mammals and birds. Amur tigers are found through eastern Russia, Manchuria and Korea. Unfortunately, these cats are listed as endangered due to poaching and habitat destruction.
