Haha, you got me there. I do--in fact--hate cats.
But, the moniker comes thanks to the long, flowy blonde mane that sat atop my dome during my senior year of college. I embraced the name bestowed upon me by my peers, and a las, The Big Cat was born.
On a related note, a girl I know here in Chicago has my exact same initials (all three) AND she acquired the nick name "Big Cat" around the same time I did, which was about two years before we met...amma right?
