This is a figurative statement, 'cattles falling from the sky'. Although, there has been cases of some other animals falling from the sky but not a cattle. This is even laughable to a certain extent, because the weight of a cattle is enormous.
I have witnessed something similar to people but it was not like this about a pigeon and all, it was a catfish. Some had the opinion that the fish fell from the sky, but that seems too extreme.
