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. If someone looks very proud or satisfied with himself, we say he looks like the cat that ate the canary.
在美国，猫是最受欢迎的宠物。所以，有许多关于猫的短语就不足为奇了。有些猫喜欢抓小鸟，比如金丝雀。如果有人看上去非常自豪，或者说对自己非常满意，我们可以说，他非常得意洋洋，像抓住金丝雀的猫一样(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 her little brother and then take it away when he reaches for it.
所以，如果你对某人欲擒故纵(play cat and mouse with someone) ，也就是说你在和某人打交道时行为反复。例如，一个小朋友可能给他的小兄弟一些糖果，但是小兄弟刚刚伸手够到的时候他就拿开了。
