Tonight as we were watching the tube, a possum came on the front porch and started munching on the cat food for our outside cat. It just stared at us like we weren't there. Didn't seem to mind us at all. Our girls our out back locked up good in an enclosed coop, never had any trouble there. This is the first possum I've seen in 10 years, at least on our front porch. Is there a threat for our girls if there is this non- fearful critter around? And what should we do if it keeps hanging out? Any suggestions? Steven and Cheryl Williams.
