    There is little doubt that house cats first developed naturally from ancient wild cats. The closest relative is the African wild cat which still lives in Africa today. This is un?derstandable because the first house cats came from Africa.

    Cats first started to live around people in Egypt about 6 ,000〜7,000 years ago. From Egypt,cats started to move around the world. This is about the same time that Egyptians began storing grain (谷物) in buildings. Scientists used to believe that people tamed cats to catch mice and protect the grain. However,cats don't like to be told what to do!Now,scientists believe that cats followed the mice and learned to accept people. Finally,some of the cats began to grow comfortable around people. These were smaller cats that nee?ded protection. As these cats and people got used to each other,then they moved in together. Around 5,000 years ago,cats started to live with people.

   Soon cats were inGreece,then the Middle East andChina. They moved along Egyptian business roads keeping away mice and keeping people around them. After the Romans came toEgypt,they also accepted the cats and brought them to Eu?rope. These cats likely bred (繁殖) with other cats to form the many kinds of house cats we have today.

   Cats are relatively recent house animals. House cats still have a lot in common with their wild relatives. Cats sleep a lot to save energy just like wild cats. They will often get food at night as well. House cats are generally peaceful and friendly,but be careful!If a cat feels it is in danger,it will fight back —just like a wild cat!
