Not anything like a Moccasin, but when we came back from the Springfield NSRA Memorial Day doings we found a strange "scat" by an upstairs doorway. I searched the whole house for a couple of hours, and finally told my wife that whatever it was must have gone out the way it came in. The next day (Monday) she was down stairs doing some routine cleaning and I heard a yelp - "Roger, I think I found it, and IT'S A SNAKE!!!" I went down and sure enough we had a 3' black snake curled up behind a box in a spare bedroom. I made a "snake catcher loop" from a polesaw trimmer, and in a few minutes had the snake captured, wrapped on the pole and restrained by the snare loop. I am not a snake fan at any level, but I know that black snakes, garter snakes and other non-venomous snakes do no harm so this one was catch and release. I learned later that snake scat is kind of unique, having both fecal and urinary material in one discharge making it easier to identify.
