Cats are like oysters, in that no one is neutral about them; everyone is, explicitly or implicitly, friendly or hostile to them. And they are like children in their power of discovering, by a rapid and sure instinct, who likes them and who does not. It is difficult to win their affection; and it is easy to forfeit what is hard to win. But when given, their love, although less demonstrative, is more delicate and beautiful than that of a dog.
