Raining Cats and Dogs - Meaning, Origin and Usage

Is the rain pouring down outside right now? If so, you could say that it's "raining cats and dogs." This post unpacks the meaning and origin of this expression.


If you're driving through a severe rainstorm, then you can say it's "raining cats and dogs." It's a somewhat peculiar expression since cats and dogs don't rain from the sky. Some people believe the phrase comes from a cat's avoidance of water and its need to run for cover rather than remain outside in the rain.

When you tell someone that it's raining cats and dogs, you're telling them that it's raining hard. The saying doesn't apply to small thundershowers or light rains. If it's raining cats and dogs, it's a real downpour. The expression can apply to a storm whether you are caught in it or safe at home.

Example Usage

Language experts are unsure of the origin of the saying, "raining cats and dogs." However, they can trace the early forms of the expression back to as far as the 17th century, where Richard Brome used a similar version in his comedy play, "The City Wit or The Woman Wears the Breeches," in 1653.

The saying refers to being caught in stormy weather, using the following line.

"It shall raine... Dogs and Polecats".

While "polecats" are not the same as the housecats we assume in the phrase today, it's essentially the same meaning. The first use of the modern term appears in the writings of Jonathan Swift, in his book, "A Complete Collection of Polite and Ingenious Conversation," published in 1738
