AVClub: I got in an argument once with a friend over which was better: cats or dogs. My friend’s reasoning was, a cat is a ruthless, calculating predator, a hunter with only the barest trappings of domestication. A cat rarely comes when you call, and hardly ever seems happy to see you. A cat’s love, then, has to be earned. A cat won’t love just anybody, and that makes the affection it does show more valuable. Dogs? Dogs are easy. Dogs don’t take effort. A dog wags its tail at any idiot with a kind word.
