Imagine this: you are sitting around on your couch relaxing with your favorite animal companion. Your dog or cat is being really lazy, just lying there, when suddenly your pet jumps up and bolts for the door and you have no idea why. There have been no changes inside the house, and there are no noises coming from outside. You might get up and see what's at the front door, or you may just dismiss your animal as crazy. But could your pet's seemingly inexplicable flight be the first warning sign of an impending disaster?
