I doubt it; it would probably just be a natural competitive advantage to be against others having more or getting treated better, which is a kind of more. Grooming in mammals is a survival benefit, after all. And I think that what we consider animals "learning from humans" is mostly them just learning how to get the most out of their magical food/shelter source. I mean, when a cat rubs its head on a person, it's just sharing its scent with the pack. And when a dog licks your face, it's just finding out what you ate, hoping that you'd share, you unsharing alpha bastard with the pizza and chicken. And that leads to the real difference between cats and dogs. Dogs have gained their survival advantage because they make you believe you're the alpha, cat's don't give a crap, because they know they're the alpha. And if you think you're the alpha in the dog relationship, just stop feeding them for a few days; you'll quickly find out who is who, my friend :-)
