Did you know that if you mention the term "Pet Cat" to fans of other teams you'll probably draw nothing more than a blank stare? Yet among Cowboys fans, almost everybody knows what a pet cat is. Why is that?
"Pet Cat" is a Parcells-ism, a term Bill Parcells popularized among Cowboys fans during his tenure as head coach in Dallas. The term initially referred to a prospect a coach, scout or owner had taken a particular liking to, often based on little more than a whim, and whom they would then try to draft, regardless of what the scouting consensus was.
