The idiom "rain cats and dogs" means that it is raining very heavily. It is used to describe a situation where it is raining so hard that it feels like animals are falling from the sky.
For example, you might say "I can't go out right now, it's raining cats and dogs outside!" This means that the rain is so heavy that it would be difficult to go outside without getting completely soaked.
The origin of this idiom is unclear, but there are a few theories. One theory is that it comes from the Greek expression "cata doxa," which means "contrary to experience or belief." Another theory is that it comes from the Old English word "catadupe," which means "waterfall."
