   Red pandas and giant pandas share a name and a fondness for eating bamboo，but they are actually not closely related.Red pandas do，however，have a lot in common with other animals.For example，red pandas are about the size of a house cat.They spend a good part of their day behaving like cats，too.They lick their paws and fur to clean themselves.Then when they sleep，they curl（卷曲） up just like a cat，using their tail for a blanket.Like raccoons（浣熊），red pandas dip（浸） their paws into water to wash their faces.And like skunks（臭鼬），who spray（喷射）a pungent scent（气味），red pandas will spray a stinky（发恶臭的） smell to defend themselves if frightened.
   Because red pandas have beautiful bright red colouring and look like foxes，they are sometimes called firefoxes.Their bodies are red and white，but their legs and stomachs are black.These colours help them keep safe among the branches of trees that are covered with a reddish-brown moss（苔藓）.
   Red pandas spend most of their time eating bamboo up in the trees of forests in India，Nepal and China.Since bamboo leaves do not provide a lot of energy，red pandas have to eat a lot of bamboo.In fact，some red pandas will eat about twenty thousand leaves a day!
