Peculiar Raine/Origin

Origin
Raining animals is a rare meteorological phenomenon in which flightless animals "rain" from the sky. Such occurrences have been reported in many countries throughout history. One hypothesis offered to explain this phenomenon is that strong winds traveling over water sometimes pick up creatures such as fish or frogs, and carry them for up to several miles. However, this primary aspect of the phenomenon has never been witnessed or scientifically tested. The English language idiom, "It is raining cats and dogs" (referring to a heavy downpour), is of uncertain etymology, and there is no evidence that it has any connection to the "raining animals" phenomenon.
