Last night around dusk, I was out the front of my property picking up some branches off the footpath. Suddenly there was a thud, less than a meter away from me on the concrete path. Looking down I saw a very young Ring tail, lying motionless. I picked it up and it opened it's eyes, so I raced it into the house and placed it in a ( sorry, Mary Anne ) box, with some old rags. Thinking it most likely was injured from it's fall, I rang the vet, but they just put me off, saying they would only take it if it was injured. I kept it over night in the computer room, and i could here the occasional scratching coming from the box. This morning when I woke I jumped on line and the possum was still giving the occasional scratching. I decided it was time to let it go, so I took the box to the base of the tree from which it fell and opened it. Alas! no possum. Now my computer room is also the junk room and houses my massive rock collection, my massive stamp collection and a collection of 100's of 1000's of Met tickets. It also contains many boxes and book cases. No where to start. My first quick scan of the entire room did not locate said possum. Then a though came to me, the door has always been open. It could be anywhere in the house. At this stage I though, " hopeless looking for it, I will just have to wait until we here it. I do not know how it escaped from the box, as I had an elastic band around it and one of my stamp stock books standing on it. So does any one have a solution to my problem.
