It’s this cat’s turf and don’t you forget it.The word ‘cat’ is also used for other felines. Felines are usually classed as either big cats or small cats. The big cats are well known: lions, tigers, leopards, jaguars, pumas, and cheetahs. There are small cats in most parts of the world, such as the lynx in northern Europe. The big cats and wild cats are not tame, and can be very dangerous.
