Leon was a postman．Every day Leon would wake up and feed his 37 cats．Leon didn't really want 37cats，but one by one they had appeared on his doorstep，and Leon had taken them in．

Every day，after feeding the cats，Leon would collect the mail from the red postboxes in the village and take it home．"If only I had 37helpers instead of 37cats，my job would be so much easier，"Leon thought．Just then，the cats started meowing for their dinner．That gave Leon an idea．That night，Leon worked late making 37cat﹣sized postal backpacks．Then，he went around to each postbox，putting up signs that read：Postbox closed! Please use the postal cat service．

The next day，Leon put a backpack on each cat and dropped off the cats around the village．Leon knew that the cats would be happy walking around all day．He also knew that they would always come home for dinner．Leon spent the day relaxing，waiting for his helpers to return．Leon was right．The cats did return，but they did not bring home many letters．Some got the letters wet．Some bit off the corners of the letters．Some even lost their backpacks．""Cats are just too unreliable（不可靠的），"Leon thought．

Just then，a strange sound came from the outside of Leon's door．A dirty dog was waiting to be invited inside．That gave Leon an idea．
