Cats are better because they THINK they are--it was something along the lines of:
A dog sees a human as the source of all of their food, water and affection and conclude the human is very powerful and important so he must be a god. Whereas a cat will take the same exact situation and conclude that "this human serves me--he brings food, water, care and is grateful when I allow affection...therefore, I must be a god...."
Anyway, that is not the exact quote but you get the gist of it.
