Tornado predictors?

Those of us who have lived through tornadoes know that they are the most unpredictable weather phenomenon, and professional meteorologists would agree. Unlike hurricanes, tornadoes are “sneak attacks,” appearing suddenly, lifting and touching down with no rhyme or reason.

So how is it possible that cats sometimes seem to know a tornado is coming? There are several stories about mother cats moving their kittens out of a house or barn hours or even days before a tornado destroyed the site. Sheer coincidence, or do cats have a “storm sensor” that we humans do not possess?
