What is it about cats that so fascinates humankind? Those who love them extol their fiercely independent natures, their lithe and beautiful lines, intelligence, and adaptability. They show endlessly cute pictures of kittens and cats playing, purring, cuddling, and meowing. On the other hand, I have seen Facebook posts where cat haters talk about how stealthy, unintelligent, nasty, and evil they are. Those people describe some of the things they would do if a cat was ever unlucky enough to sneak in their houses. That kind of polarity has been around for eons.
