In regard to the origin of the domestic cat, naturalists have squabbled and fought for centuries, and the best thing possible, I think, is for every man steadfastly to retain his own opinion, then everybody is sure to be right. For myself, I really cannot see that it would either assist us in breeding better cats, or render us a bit more humane in our treatment of the pretty animal, to be assured that she was first imported into this country from Egypt or Persia in the year one thousand and ever so much before Christ, or that the father of all the cats was a Scottish wild cat, captured and tamed by some old Highland witch-wife a thousand years before the birth of Noah's grandfather. What matters it to us whether the pussy that purrs on our footstool is a polecat bred bigger, or a Polar bear bred less? There she is,-- The rank is but the guinea stamp, And a cat's a cat for a' that. But, and if, you are fond of pedigree, why then surely it ought to satisfy you to know that, ages before your ancestors or mine could distinguish between a B and a bull, pussy was the pet of Persian princes, the idol of many a harem, and the playmate of many a juvenile Pharaoh. What classification, then, are we to make of cats? We search around us in vain for something to guide us; then, fairly on our beam-ends, are fain to clutch at the only solution to the question, and fall back upon coat and colour, with some few distinctive points of difference in the size and shape of the skull and body. Colour or markings, then, and quality of coat, are the guiding distinctions between one breed of cat and another; and to these we add, as auxiliaries, size and shape. _Colour_.--Whether we understand it or not, there, undoubtedly, is nothing in this world left to chance alone, and nothing, I sincerely believe, is done by Nature without a purpose. The same merciful Providence that clothes the lambs with wool, the reason for which we can understand, paints the rose's petal, the pigeon's breast, or even the robin's egg, for reasons which to us are inscrutable, or only to be vaguely guessed at. We can tell the "why" and the "wherefore" of the rainbow's evanescent hues, but who shall investigate the laws that determine the fixed colours of the animal and vegetable creation? Who shall tell us why the grass is green, the rose is red, that bullfinch on the pear-tree so glorious in his gaudiness, and that sparrow so humble in his coat of brown?
