Hot summer days make us tired and lazy.Animals feel hot too.Most of them have thick fur（厚厚的皮毛）and always stay outside.To beat the heat，animals have many great ways.Let's take a look!
    Koalas-hug（抱聚）trees
    Can hugging a tree help to cool off？Koalas say， "Yes!" Trees are cool in hot weather.So koalas hug trees to give part of its heat to the trees.The trees also give shade to the cute animals.When it's not very hot，koalas usually lick（舔） their legs to cool off.
    Tigers - swimming
    You are not the only one who likes to swim in hot days.So do tigers.During the hottest part of the day，tigers often swim in a river for some time and then stay in the shade（樹蔭）.They hunt（捕食）at night，early morning or late evening.
    Cats-shedding（褪毛）
    If you keep a cat at home，you may find that it sheds a lot more in summer.Do you know why？In cold weather，most house cats grow thick fur to stay warm.But in summer，they shed to cool off.Cats also lick their paws to keep cool.
    Pigs—mud baths（泥?。?br />    We think pigs are dirty when they have fun in the mud.But in fact，they do that to cool themselves.With a lot of body fat，pigs have a lot of heat in their bodies.Staying in mud cools a pig's body by up to 3.6℃.It is really useful.
