Cats use the three sensory channels for communication; [[Eye - Anatomy & Physiology#Vision|sight]], [[Ear - Anatomy & Physiology#Function - Hearing|sound]] and [[Nose - Anatomy & Physiology|scent]]. Each of these has certain advantages and disadvantages for communication. Communication in the cat has evolved to enable cats to '''maintain distance from each other both in time and space''', primarily through a system of '''chemical signals'''.

===Affiliative Behaviour===

===Affiliative Behaviour===

In the typical affiliative behaviour, a cat will approach and then move its '''tail into a vertical position''' (tail-up). A '''quiet trill or chirrup''' is issued, and after getting to within around 0.5 metres the approaching cat will '''sit down'''. '''Slow eye blinking''' is also used to indicate that this is a friendly approach. Physical contact only occurs between cats in in about 30% of these approaches. Two cats may approach each other with tail-up, in which case they will often sit down in close proximity, but still without physical contact. When cats do make contact during a greeting, it is often only briefly; one or two rubs or a brief period of grooming. Cats that are younger than 2 years of age are more sociable and also more likely to engage in closer contact after a greeting, possibly even playing.
