“When a man loves cats, I am his friend and comrade, without further introduction.”
Mark Twain was a known lover of cats. This is a common trait of geniuses. Albert Einstein, Isaac Newton, Albert Schweitzer, Ernest Hemingway, T.S. Eliot, … the list is long and distinguished.
There are fundamental differences between cats and dogs that explain why some of us love them so. A dog consists primarily of unconditional love and absurdity, in equal measure. His life is devoted to pleasing you and earning your company. He will often reward even the meanest person with loyalty and devotion. A cat consists of grace, cool self interest, and independence. A cat’s respect and love must be earned and maintained, which makes a cat very like an emotionally healthy human.
Ideally, a person will love both cats and dogs, but among those with a strong preference for one or the other species, there are definite tendencies. Those who desire control over others and want to feel superior tend toward dogs, while those who prefer to treat all as equals and prefer to earn the respect of all, even the non-humans among us, prefer cats. This is a generalization, and like all generalizations is not to be relied on too heavily, but I’ve found it quite accurate in practice.
