Some little boys and girls do not clean their nails every day. Then sometimes a piece of dirt gets in under a nail and causes a sore. But the tiger and tigress are wiser. If part of a piece of meat that they have torn up were to remain under a claw, it would fester and cause a sore. So the tiger and tigress clean their claws every day. _The Feline Has Padded Paws_ The paws of every feline have also a special quality. The under part of each paw is thickly padded with powerful muscles. That gives the feline three advantages. First advantage: it enables the feline to _stalk_ its prey. That is, the feline can creep up to its prey quite silently. As its paws are padded, they make no sound on the ground--just as your footfall makes no sound when you wear rubbers over your shoes. Second advantage: the padded paw enables the feline to strike down its prey with a severe blow. When it wants to strike down its prey, the feline hardens the muscles under its paw; the blow of its paw is then something like that of a hammer. A tiger has often been known to smash the skull of a buffalo with a single blow of its paw. Third advantage: the padded paws enable a feline to leap farther. After a feline has crept up as near to its prey as it can, it has still to leap upon its prey to seize it. Then the muscles under the paws act like springs, and enable the feline to give a big leap. Even in running, the muscles act somewhat like springs. You must have noticed that, in running, a dog _gallops_, but a cat _bounds_. That is, the dog moves its legs very quickly, but each space of ground it covers is not very long. A cat moves its legs not quite so quickly, but the space of ground it covers at each bound is much longer. The cat and all felines can give a bigger bound because of the muscles under their paws. Having told you all the qualities common to animals of the Cat Tribe, I shall now describe some of these animals in detail. CHAPTER VI The Tiger The tiger lives in most of the countries along the south coast of Asia, that is, all the way from Persia to China. Some tigers are also found in the northern countries of Asia, such as Siberia; but there are very few of them there. And, of course, these few tigers in the cold northern countries of Asia are a little different from those in the hot southern countries. For the tigers in the cold countries have thick fur on their skin, and a layer of fat under their skin--just to keep them warm. So they are too fat to be as muscular and active as the slim and lithe tigers that live in the hot countries in the south of Asia. Now please remember one thing more about the dwelling place of the tiger: _there is no tiger in Africa_. Even clever people do not always know that. When ex-President Roosevelt went on a hunting trip to Africa a few years ago, he shot many wild and ferocious animals there, and some newspapers said that he had shot several tigers.
