So this is proverbs explained.

Today, we're going to look at the proverb "It's raining cats and dogs."

Raining cats and dogs? No one ever thought this is actually possible, not even a long time ago, like, in the 17th century.

But in that time, people threw their waste on the streets, just like that, so the big cities were...a mess.

Between all that waste, there were animals living and—don't get scared—they died there as well.

Unfortunately, there was no one to clean up all the waste, so when it started to rain—no, no, like, rain a lot— everything would wash away, including those dead animals.

That's why when people saw heavy rain, they would say, "It's raining cats and dogs."
