Nugget of Knowledge: Animal instinct for weather

Animals can sense changes in air pressure before storms

(WYTV) - How does your cat know a storm is coming, say, an hour before you do?

What magic is at work here?

Not just cats, but many other animals are much more sensitive than humans to sounds, to smells and to changes in atmospheric pressure. That's why your dog wants to come inside before it rains.

Their heightened senses can allow them to pick up hints that a storm is just over the horizon well before you catch wind of it, and we warn you on TV.

Before a storm, your cat's inner ears may detect the sudden fall in atmospheric pressure, and she may have learned to associate this with a storm on the way.

Birds and bees apparently sense this drop in barometric pressure as well. They take cover in their nests or hives. 

If a storm is already raging some distance away, your pet will hear the faint rumble of thunder before you do.

And, your cat may be able to smell the incoming rain, maybe miles away, or get a whiff of ozone gas. That's the sharp, metallic odor that lightning creates.
