I picked this up from Wikipedia...It`s about cat`s body language
Many people fail to understand the silent body language of cats. In particular, people who are accustomed to the outwards signs of dog body language seem slow in detecting what a cat is telling them in its body language, which creates the false impression that cats are cold-hearted, unemotional, or unintelligent. To understand cats, one must observe a feline closely and learn what its body signals tell them. It is important to keep in mind that each cat may display its emotions with different body language. The flattened ears, teeth showing, baring belly for submission are easily 'read' by humans. Some characteristic signals, however, are often misunderstood. For instance, a cat rubbing its body along an arm or leg of its human is not only a way in which to attract attention and, perhaps, a morsel of food; it is also a way of 'marking' its human as its own. Using scent glands located around its mouth and elsewhere, it subtly 'marks' its human as part of its cat territory. Most cats prefer gentle rubs behind the ears. To inform their humans they need petting or attention, a cat may push its entire body weight up against the human as the cat snuggles next to his favourite person.
