Cute isn't he? Since we moved to our current house just over three years ago we have had so many possums in our roof that we bought our own trap. My sister feeds her family of possums but that is because she doesn't have them living above her head! They fight and make disturbing screeching mating calls, urinate everywhere (and it smells horrid) and I'm quite sure that our erratic loungeroom lighting has quite a bit to do with them tangling their toes in the wiring.
They are seriously easy to catch, it literally only takes minutes (they must have very sensitive nostrils). Take a slice of bread and smear it with peanut butter and some jam, set the trap and wait. You should soon hear thumping as it's bounding little body dances across the beams and then SNAP! the door shuts. Cute but not too bright. This morning I let this juvenile male go up a tree near the dam and he made light work of the climb.
