7．Cats are the most popular pets among Americans．So it is not surprising that there are many expressions about cats．Some cats like to catch small birds，like canaries （金丝雀）．If someone looks very proud or satisfied with himself，we say he looks like the cat that ate the canary．
Sometimes，a cat likes to play with a small animal it catches．
So if you play cat and mouse with someone，you change between different kinds of behavior when dealing with another person．For example，a child might offer something sweet to his little brother and then take it away when he reaches for it．
You may have known that cats spend most of their time sleeping．Sometimes people sleep for a short time during the day．This is called a cat nap．
If you tell about something that was supposed to be a secret，we say you let the cat out of the bag．If you are not able to speak or answer a question，someone might ask if the cat has got your tongue．
Have you ever watched children in the classroom when their teacher leaves for a few minutes？"When the cat's away，the mice will play．"will best describe that situation．
You may have heard this expression：curiosity （好奇心） killed the cat．This means being too concerned about things that are not your business might cause problems．
If your home is very small，you might say there is not enough room to swing a cat．But you probably should not try this at home!
