It’s Raining Cats and Dogs Origins
Many sources claim that it’s raining cats and dogs is an extension of the term “like cats and dogs” from the later 16th century. “Like cats and dogs” was commonly used to describe strife or enmity as a reference to dogs being the natural enemy of cats—and thus a nod to their violent fights.
In “The Schoole of Abuse, Conteining a plesaunt inuective against Poets, Pipers, Plaiers, Iesters and such like Caterpillers of a Commonwelth,” this animosity is first documented in a figurative manner. This particular reflection was written by Stephen Gosson, a Church of England clergyman, in 1579:
He that compareth our [musical] instruments, with those that were used in ancient times, shall see them agree like Dogges and Cattes, and meete as iump as Germans lippes.
The oldest known use to describe weather occurred in 1651 in “Olor Uscanus,” a collection of poems by Henry Vaughan in which he alludes to a roof that was secure against “dogs and cats rained in shower.”
Jonathon Swift was also a fan of the expression, often including it in his various publications. It is seen in his satirical poem “A Description of a City Shower,” published in the 1710 collection of the Tatler magazine. The poem was a satirical denunciation of contemporary London society.
Sweeping from Butchers Stalls, Dung, Guts, and Blood,
Drown’d Puppies, stinking Sprats, all drench’d in Mud,
Dead Cats and Turnip-Tops come tumbling down the Flood.
Swift also uses it in POLITE CONVERSATION IN THREE DIALOGUES, published in 1738:
“I know Sir John will go, though he was sure it would rain cats and dogs”
When you use the idiom it’s raining cats and dogs, you are describing a torrential or heavy downfall of rain. It creates an emphasis on the storm and also adds interest and description to your speech (or writing) in a figurative manner.
Although the exact origins are questionable, the term is likely an extension of the figurative use of dog and cat fights, which can be quite violent and intense.
