I suspect that one of the dogs in this video isn’t real. So he’s bound to have atypical reactions.
The cats are all real, and seem to have an aversion to human feet… and socks. One of those funny faces that they make, by the way, is how they check out the smell with a sense organ that they have and we don’t. It’s called Jacobson’s Organ, only nobody named Jacobson actually has one.
