In 1961, a man found a strange cat on his farm in Scotland. The cat’s ears were folded, bent forward, on its head. In fact, this was a new kind of cat. People named it the "Scottish Fold(苏格兰折耳猫)".

The Scottish Fold has a round head and large eyes. Its neck and legs are short, which makes it look very cute. Interestingly, all the Scottish Folds are born with straight and unfolded ears. And when they are growing up day by day, some cats’ ears will begin to fold. So, the Scottish Fold comes in two types: folded ears and straight ears.

Besides, there is a nickname for the Scottish Fold. It is the " Messenger of Peace". Why?

Because the Folds are sweet and friendly animals. They can get along well with other cats. And

unlike some other cats, they can even get along well with dogs! In many different environments, such as at a noisy house, or in a cat show, you can see them playing with other animals happily.

Well, when you come to a new school, do you think it’s difficult to adapt to the new environment? Perhaps you can learn from the Scottish Fold. That is: always be sweet and friendly to others.
