Every morning, we put on our clothes, and then go to school or work. What about animals? What do they wear? Fur? Yes, fur（皮） or hair is the animals’ clothes. Just like our clothes, fur or hair can keep animals warm. However, not all animals have fur or hair. A few animals, like the sphinx cat(狮身猫), are hairless. That’s because they grow up in a special way. Some sphinx cats have very fine hair, but if you don’t look carefully, you can’t see it. The fur of this kind of cat Feels like the fur on fresh peaches. Another animal, the elephant, doesn’t have any fur. They live in hot places, so they don’t need fur to keep warm. They use mud and water to keep themselves cool. Whales(鲸) spend all of their time in water. Their body fat keeps them warm, so they Don’t need fur either. Do humans have hair? Yes, of course. But our hair is shorter and thinner than animal hair.
