Can pets read human emotions?

I certainly think it depends on the animal. But I have no doubt they cats can sense emotion. I've had cats through good times and had, and the cats I've had definitely know. I've never had much for dogs, but I've seen the same with some dogs and their owners.

And on another note, reptiles can definitely sense emotion in a way, though its completely different. There are people who say they can sense fear, and I think what ever it is they can sense is more based on slight physical signs.
