Cats.

As we cat owners now, we are simple servants that have been graced with task of servicing our feline superiors. For now.

Well, that may be true. I've heard that when a dog sees its master loving it, feeding it, caring for it (minus the vet visits, I guess), the dog thinks "My master must be god." When the cat sees its humans treating it well, the cat thinks "I must be god."
