"They say animals have a sense of impending earthquakes"
Yup. And there's some evidence for it. However, they're not long-range predictors. I think it's just that they feel earth movements too small for we big old humans can feel, so they feel the earthquake before we're aware of it.
I know my cats scurry under things during earthquakes. Now that my wife and I have moved to Minnesota, they'll probably be bored. Still, I can't wait for the first snowfall...just to see how they react to snow for the first time. I'm ready for some serious laughing.
Earthquakes for Snow? hmmm Your Kitties will proably think they will have one humongous clean liter box!
