===Communication===
Visual communication involves '''facial and body postures''', as well as the '''visual aspects of''' certain behaviour such as '''spray marking''' and '''clawing'''. In general, visual communication is operates over a limited range, in line of sight and is rapidly modified. This gives the signaller a great deal of control over the signal, which can be changed according to the response it elicits. Visual signalling is less effective at night, in adverse weather conditions and dense undergrowth. The main disadvantage of visual communication is that it must be delivered face to face with a competitor, which increases the risk of conflict and injury.

Visual communication in cats therefore tends to be vivid. '''Whole body signals''' are used to make the signaller appear larger and more threatening, or smaller and less threatening. The most powerful signals are those at the extreme, such as the side-on body posture with arched back and tail erect.
