Cats, Part One Cats are interesting animals. Many people have cats at home as pets. These are domestic cats. They may seem quite independent,# but they depend on you for food and shelter. They meeow when they want to be fed,# or want to go out. Sometimes they seem quite wild# and go out looking for birds or mice. They might bring them back home,# offering them to you as a present. You may not want a half-eaten mouse as a present,# but your cat does not know this. Cats also like to be stroked. They sometimes like to sit on your lap. Quite a few like to be tickled under the chin,# or behind their ears. Then they will purr, often quite loudly. Imagine doing that to a tiger,# or a lion, or a cheetah! But tigers, lions and cheetahs are also cats. They are not domestic cats, of course. Though some foolish people# try to keep them as pets. They are wild cats. In scientific terms, they are called big cats. There are plenty of similarities# between your cat and the big cats. Both have very strong jaws for their size. Both have long canine teeth# for piercing and ripping flesh. Both have claws which they can sheath #for padding along the ground# or up a tree,# and then suddenly reveal when they need to attack. But there are also differences of course. You may think that is obvious:# big cats are big and domestic cats are small. You are right,# but this is not actually the main distinction.
