I like 'possums too! Some years ago I lifted the top of the trashcan to find a cute little "baby Meezer" sleeping on the very stinky trash bags (it was 90-100 degree summertime). It hissed cutely but never really woke up. As I stood there looking at it, trying to figure out what was weird about it, I realized it was a baby 'possum!! To this day, I don't know how it got into the closed trashcan.
