Dunno. Could be. I know we put out catfood and water for them on a daily basis. I even have to chase off the occassional raccon or possum. Tempted to pay the tax/registration and get a silencer/suppressor for my bolt action .22LR. I've never tried possum stew before...
LOL!
Sometimes, if animals are left to wander, they instinctively use things that help them. Sometimes they wallow in things, and we think they are scratching their backs.
I've heard possum stew was good, but...:o|
