I think it is incredibly rare (if not impossible) for two women to strike up a friendship after a catfight. It can be done with boxing and wrestling (and I've done it) because there is structure and rules, and an element (however faint) of respect for one's opponent. Catfights are all out bouts of passion, sometimes new, sometimes long festering. These are things that you either come out as the winner, looking down at your opponent, or as the loser, hating the victor and wallowing in your shame. I've been in a few catfights and not one among them was with a woman I'd ever declare to be my "friend".
