Humans can go to the hospital when they're ill．But as for animals，what should they do？To stay healthy，animals have their own ways to heal（治愈）themselves．Now let's get to know their special skills．

Skill One

Have you ever seen your dog or cat lick（舔）its wounds？Why do they do it？It probably feels good，but it's good medicine．Licking cleans a wound，and saliva（唾液）has chemicals that kill germs（细菌）．

Skill Two

To avoid diseases，many animals have good living habits．They hate to be dirty．Most animals separate their pooping（lF1E）areas from their eating areas．Horses poop far away from the grass they eat．Rabbits put their poop in special pooping areas．

Skill Three

Have you ever heard of the expression "starve a fever（发烧时宜饿）"？Many animals stop eating when they're ill．When a sick animal stops eating，it can stop germs from getting necessary things．

Skill Four

Another way that animals heal themselves is to raise their body temperature．High temperature can kill germs．Warm﹣blooded animals（like us）get fevers to fight with germs．Cold﹣blooded animals（like snakes）look for pieces of wood or rocks heated by the sun．Fish move to warmer waters．
