This little guy showed up over a week ago. The persistent feline stayed around despite the fact that we didn't feed him for 6 days. He slept on top of Chubby's heated outdoor house, soaking up the leftover warmth. With 20-something degree highs and over 6" of snow, we relented and began to feed him. He hasn't let us get close enough to pet him yet, but he stays close and is quite the conversationalist.
Chubby (in the background) is not thrilled, but tolerates him.
