The cat makes himself as big and

aggressive as possible to try and frighten the dog away.
I recommend that you take advantage of your opponent's
reaction to you posturing and make your get away as soon as
possible. We have already spoken about the adrenal
syndrome, how it can effect the human body and how the
reasoning process mistakes adrenaline for fear, thus
triggering the 'flight' response. By giving an opponent an
adrenal release, we trigger the natural instinct to either freeze
or run. Both of these would have been very natural defences
against prehistoric beasts that were too fearsome to stand and
fight or whose eyesight was poor and would not be able to
see a frozen enemy, only attacking when they sensed
movement. In this society 'freezing' or 'running' is not always
an option and may only get you battered by an antagonist
that will use a frozen adversary as a punch bag.
