to be the cat's whiskers 是一个老式表达，指某人成为了了不起的人物。
- Mary thought she was the cat's whiskers in her new coat.
- This is a posh school and everybody thinks its students are the cat's whiskers but the teachers know they are not!
值得注意的是，在英语里，人们用 look like something the cat dragged in 这个表达来形容某物很脏或看起来很邋遢。
- My friends and I went to Rio last year during the Carnival. After partying all day and all night, we looked like something the cat dragged in.
