So far most of the animals I have described to you are vegetarians, that is, they eat vegetables of all kinds, for even leaves, herbs, and grass may be classed as vegetables. These animals are the elephant, the buffalo, the deer, the antelope, and others. The bear is the only animal I have so far described to you (in Book I) that eats both vegetables--that is, the roots of trees--and the flesh of other animals as well. But now I shall describe to you quite a different class of animals, namely, animals that eat only meat. Among these animals the most important group is the Cat Tribe, or the _felines_, as they are sometimes called. They possess many of the qualities of the ordinary cat. The principal felines are the tiger, the lion, the leopard, the puma, and the jaguar. All felines have a special kind of fangs, tongue, claws, and paws, which I shall now describe in detail. _The Feline Has Strong Fangs_ Besides the ordinary teeth, every feline has two pairs of strong fangs which look like big projecting teeth. One pair of fangs is placed on the upper jaw, pointing downward; they are wide apart. The other pair of fangs is placed in the lower jaw, pointing upward; they are not quite so far apart as the fangs of the upper jaw. Why? So that the animal can close its mouth comfortably without striking the lower fangs against the upper fangs. These fangs are three to four inches long in a tiger or a lion; they are not quite so big in a leopard or other feline. The fangs of the tiger or the lion are so strong that he can hold down a heavy bullock by gripping it with his fangs. He can also drag the bullock along the ground by gripping it in that way, and can use the fangs to tear out a large piece of meat from the body of his prey. When the tiger or the lion gets a piece of meat into his mouth, he uses the upper fangs to pierce the meat: that is, the meat lies on the ordinary teeth on the under jaw, and the two fangs of the upper jaw come down on the meat and cut it into two or three pieces. The tiger or the lion could chew the meat a little more, with the help of his ordinary teeth, but he does not need to. Every animal of the Cat Tribe has a strong digestion; so the tiger or the lion merely cuts up the meat a few times with his fangs and then swallows it. _The Feline's Tongue is Rough_ A feline's fangs, however, are too big to tear off _small_ pieces of meat from a bone. So it uses its _tongue_ to scrape off the small pieces of meat. That is the reason why a feline's tongue is very rough. So again you see, as I told you in Book I, that every animal has the gift it needs. If the feline did not have a rough tongue, it could not eat the small pieces of meat on a bone; and so a portion of its food would be wasted. No inhabitant of the jungle wastes food. It is only _we_ who waste food. _The Feline's Claws are Retractile_
