To gain the friendship of a cat is a difficult thing. The cat is a philosophical, methodical, quiet animal, tenacious of its own habits, fond of order and cleanliness, and it does not lightly confer its friendship. If you are worthy of its affection, a cat will be your friend, but never your slave. He keeps his free will, though he loves, and he will not do for you what he thinks is unreasonable. But if he once gives himself to you it is with absolute confidence and affection.
— Theophile Gautier
