两只顽皮的坏老鼠阿秃和阿灰，有天趁着小娃娃小露和小珍不在，跑到漂亮的娃娃屋子里捣蛋。他们敲碎了石膏做的火腿，弄倒了小罐子，把小珍的衣服丢到窗外，还把小露枕头里的羽毛掏出来……。两个娃娃回家后，面对乱七八糟的家里，只能苦笑和瞪眼，一句话也没说。不过，后来两只老鼠再也不会这样淘气了，因为过意不去的她们，不仅赔偿了她们打破的东西，而且每天一大清早，阿灰还会去打扫娃娃屋子呢。

Beatrix Potter is regarded as one of the world's best-loved children's authors of all time. From her first book, The Tale of Peter Rabbit, published by Frederick Warne in 1902, she went on to create a series of stories based around animal characters including Mrs. Tiggy-winkle, Benjamin Bunny, Jemima Puddle-duck, Mr. Jeremy Fisher and Tom Kitten. Her humorous, lively tales and beautiful illustrations have become a natural part of childhood.
