You know Rhapsody - I've been thinking about your point about the dogs. I tried to research this (hope you have better luck than I do Pat! Let me know!) and didn't come up with much, but when you mentioned the dogs, then yes, it has to have some scientific foundation. Dogs can also sense when someone is about to have an epileptic seizure. I think our cats sense when something is wrong, and dogs seem much more... don't know... astute about emotions than cats do so it would stand to reason.
