Origin of Raining Cats and Dogs

This expression became popular in the 1800s. However, this idiom has variations that occurred even earlier.

There is a lot of speculation about the origin of this idiom. One morbid theory has more evidence than the others. It proposes that heavy rains caused flooding that would carry dead animals in the water. Sanitation in cities used to be quite poor, and trash and dead animals would often be left in the streets.

The rains could cause these cadavers and other debris to float through town.
