Where does 'raining cats and dogs' come from?
The origin of the idiom ‘raining cats and dogs’, which means to rain heavily, is unknown. One theory is that in old England, cats and dogs would sleep on the roof. When it rained, the roofs got slippery and the cats and dogs would slide off of the roofs, therefore it was, ‘raining cats and dogs’. A similar theory is that during the middle ages, when houses had thatched roofs, animals would hide in the roofs when it was raining and sometimes fell through the flimsy roofs on to the streets below.
