Animals are known to act strange before an earthquake. They run off. Those in confinement get irrate.
Dogs are also being studied to smell cancer in urine. They've been known to try to chew cancer moles off their owners.
My brother reciently babysat a friends kid over night. His dogs chewed the pant legs off the kids pants. These are nice dogs, and have never done anything like that before.
The next day, the kid got hit by a car at his aunts house, and both his legs were shattered.
Weird huh? It's a true story. Happened about 2 weeks ago.
