As a country, we tend to worship unconditional love. As the old joke goes-lock your wife and dog in a trunk for an hour, open it up, and see which one still loves you. IMO, dogs are butt kissers. If you don’t love something, you don’t deserve their love back.
I think of myself as more a dog person, but we are down to a cat pet-wise, and I would say I agree with all of the above. Our cat is a very good company. Of course, she is the most dog-like cat I have ever come across, which does not mean she views her human family as anything more than "staff."
