Are you wondering why a stray cat pops up at your front door as soon as you get home from work? Or perhaps it is propped up against the door with a look of “where the heck have you been, human? I’ve been waiting for you for hours!” Your first thought might be to shoo it away, so it doesn’t get too familiar, or give it a treat and send it on its way. But have ever asked yourself what exactly does it mean when a stray cat comes to your house?
