“A dog is a pitiful thing, depending wholly on companionship, and utterly lost except in packs or by the side of his master. Leave him alone and he does not know what to do except bark and howl and trot about till sheer exhaustion forces him to sleep. A cat, however, is never without the potentialities of contentment. Like a superior man, he knows how to be alone and happy. Once he looks about and finds no one to amuse him, he settles down to the task of amusing himself; and no one really knows cats without having occasionally peeked stealthily at some lively and well-balanced kitten which believes itself to be alone.”
