The quiet, however, is broken before long by a peculiar and suggestive cry. We do not hear it yet ourselves, but Stalker, our black cat and familiar, has caught the well-known accents, and with a characteristic crooning noise, and a stiff, perpendicular erection of tail, he sidles towards the door, demanding, as plainly as possible, to be let out. Yes, it is the cats-meat man. 'Ca' me-e-et--me-yet--me-e-yet!' fills the morning air, and arouses exactly thirty responsive feline voices--for there is a cat to every house--and points thirty aspiring tails to the zenith. As many hungry tabbies, sables, and tortoise-shells as can get out of doors, are trooping together with arched backs upon the pavement, following the little pony-cart, the cats' commissariat equipage, and each one, anxious for his daily allowance, contributing most musically his quota to the general concert. We do not know how it is, but the cats-meat man is the most unerring and punctual of all those peripatetic functionaries who undertake to cater for the consumption of the public. The baker, the butcher, the grocer, the butterman, the fishmonger, and the coster, occasionally forget your necessities, or omit to call for your orders--the cats-meat man never. Other traders, too, dispense their stock by a sliding-scale, and are sometimes out of stock altogether: Pussy's provider, on the contrary, sticks to one price from year's end to year's end, and never, in the memory of the oldest Grimalkin, was known to disappoint a customer. A half-penny for a cat's breakfast has been the regulation-price ever since the horses of the metropolis began to submit to the boiling process for the benefit of the feline race. By the time the cats have retired to growl over their allowance in private, the daily succession of nomadic industrials begin to lift up their voices, and to defile slowly along Our Terrace, stopping now and then to execute a job or effect a sale when an opportunity presents itself. Our limits will not allow us to notice them all, but we must devote a few paragraphs to those without whom our picture would be incomplete.
