The Smog: A cat bred, quite simply, to fight other cats. Owing to an unexplained occurrence of Lamarckian heredity, the Smog lost its ears in the 16th century, its tail—which opponents could hang onto—in the 17th century, and most of its hair in the ring, while its claws and teeth lengthened and toughened. An ordinary cat, going up against a Smog, might as well run into an aeroplane propeller. Good with children.
Dachskatz: An affectionate pet, often referred to as the “sausage mog”. Popular in the home that can't afford draught excluders. Also, the only cat that can brush up against the front and the back of your legs at the same time.
The St Eric: Many a weary traveller, half-buried in the snow, has hauled himself out and kept himself warm at the sheer rage of seeing a St Eric curl up and go to sleep twenty yards away. They were never a great success, since they depended on a cat's natural sense of charity and benevolence.
The Pussky: Much used by lazy Eskimos, trappers, Mounties, etc. Refuses to go out in cold weather.
The Snufflecat: This breed came into its own in the American South, when it was used to track escaped slaves and convicts, who were very lucky escaped convicts and slaves indeed because, although the Snufflecat has a superb sense of smell, it doesn't know what to do with it.
The German Sheepcat: Never very good with sheep, actually, but a great favourite with police departments across the world. The cat's natural tendency to rub up against people has, in these 150lb specimens, become a desire to smash open doors and knock people to the floor, where they are drooled on.
(The most famous German Sheepcat was the film star RanCanCan, who had a spectacular if somewhat brief career in the 1940s. Faced with bridges being washed away ahead of speeding express trains, or fire breaking out in tall orphanages, or people being lost in ancient mine workings, RanCanCan could be relied upon to wander off and look for something to eat. But very, very photogenically.)
The future of the Real cat
If you're prepared to accept the Schrodinger theory, then it is rosy—in fact, the last man on Earth will probably look out of his bunker and find a cat sitting there patiently waiting for the fridge to be opened.
Actually, theories don't come into it. Real cats are survivalists. They've got it down to a fine art. What other animal gets fed, not because it's useful, or guards the house, or sings, but because when it does get fed it looks pleased? And purrs. The purr is very important. It's the purr that does it every time. It's the purr that makes up for the Things Under the Bed, the occasional pungency, the 4 a.m. yowl.
Other creatures went in for big teeth, long legs or over-active brains, while cats just settled for a noise that tells the world they're feeling happy. The purr ought to have been a pair of concrete running shoes in the great race of evolution; instead, it gave cats a rather better deal than most animals can expect, given Mankind's fairly unhappy record in his dealings with his fellow creatures. Cats learned to evolve in a world designed initially by nature but in practice by humans, and have got damn good at it. The purr means “make me happy and I'll make you happy”. The advertising industry took centuries to cotton on to that beguiling truth, but when it did, it sold an awful lot of Cabbage Patch dolls.
You've got to hand it to Real cats.
If you don't, they wait until your back is turned and take it anyway.
It's nice to think, though, that if the future turns out to be not as bad as people forecast, ie, if it actually even exists, then among the domes and tubes of some orbiting colony, hundreds of years from now, dynamic people with sturdy chins, people who know all about mining asteroids and stuff like that, will still be standing outside their biomodule banging a plastic plate with a spoon.
And yelling “Zut!” or “Wip!”, if they've got any sense.
