I have no problems with wild animals outside, but not in the house. I also do not want to feed them.
One year the cats had ripped a hole in the screen door and I was a bit slow fixing it. All was fine until the coon came in. Hardware cloth was installed over the screen the next day.
Possums are quite likely the stupidest fur bearing animal still alive on the North American continent. My dog Buster, AKA the barking fool, has a head count well into double digits of possums that get into his pen. Too bad they're not worth skinning out these days.
