There are about forty distinct kinds of wild cats known to inhabit the earth today. They range in size from the mighty Siberian tiger to several little spotted species about the size of the average domestic cat. The cats are the most efficient land predators left on earth. They combine power, speed, patience, camouflage, and considerable individual skill. All swim well, most climb with great agility, and at least for short distances, most can move with amazing swiftness.
