Red pandas are native to the south-west of China and the eastern Himalaya region. According to estimations, there are some 10,000 left in nature, but their numbers are going down. Their habitat becomes smaller as trees are being chopped, and red pandas are being hunted for their fur. Some end up in traps intended to catch other animals.
