I agree with Beckscat, Jossie, Nikkiukcat, and Sierra -- women get in catfights because they develop a dislike for one another, often due to rivalries and jealousies, based on what I observed happen between my mom, Lois, and her friend and neighbor, Fran. When Fran first moved to our neighborhood, she and mom became fast friends, but as they grew their beautiful, thick, shoulder-length hair longer and longer over almost 3 years, an unspoken competition developed between them, fueled by the ever-growing attention and compliments they received over their lengthy locks from their husbands (who complimented their rival on her lovely tresses, too), family, and friends. During the last 10 months Fran lived next door, their friendship soured and they became frenemies as their jealousy grew, along with their hair. When Fran announced she and her family were moving in 3 months, conditions ripened for Lois and Fran to settle their differences in a way they wouldn't have if they had continued to be neighbors. A going-away party for Fran's family, and an event involving Fran's poodle, provided the fuel and the spark to ignite an extraordinary hairpulling duel which I witnessed as a boy.
