Haven't ever encountered one during the day, so your vistor may be sick. We have them here. I live in the 'burbs, but possums are alive and well. We used to leave our garage door cracked for our kitties to come and go, their food was out there too. One time we caught a possum munching away WHILE kitty just WATCHED
Another time, we pulled up in the driveway....here comes mama possum under the garage door then quickly following....3 baby possums. Guess she was teaching them where the easy food was.
My father and step mother had them come INTO the house by way of a dryer vent. They were finding possums individually, and generally new poops indicated another visitor to look for. Now one time, they knew one was in the house, but hadn't discovered it's hiding place. My step mother pulls open a dresser drawer...guess who POPS up? Yep, Mr. (mrs?) possum. My step mother said she almost had a heart attack. And you think possum pee on the porch is bad....she had to wash everything in the drawer
