thats funny!!! a few years ago we found a very young possum in our drive way that our dog had caught and tore up pretty bad. cleaned him up and put his butt in a big cage.kept him for a couple years. one nite i let him go in the woods in my back yard. 2 days layer i saw eyes lookin at me from under the old shop. that BIG guy had come back to live. he stayed there for a few years.
