Although we have never experienced a time when it literally rained cats and dogs, it actually has poured frogs, fish, and other creatures.
Raining animals is a rare meteorological phenomenon where you have flightless animals “rain” from the sky. One hypothesis explaining this phenomenon is that strong winds traveling over water sometimes pick up fish, frogs, or other creatures, and carry them for up to several miles. But this main aspect of the phenomenon has never been witnessed or scientifically tested.
Some witnesses of raining frogs describe the animals as startled, though healthy, and exhibiting relatively normal behavior shortly after the event. In some incidents, the animals are frozen to death or even completely encased in ice.
