Never underestimate a possum!

So...despite our serious attempts, yesterday evening, to block off Jnr's new sleeping quarters guess where she slept today? No, not the compact and bijou possum box I lovingly built, no, back in the same place she slept yesterday. Yes, behind the bit we blocked off! It must have been a tight squeeze because when it came time for her to rise this evening she couldn't get out again! We heard her trying to bite her way out then we heard her wriggling all over the ceiling trying to find another way out!Will was furious and was all for throttling her! We had to lever open the gap she got in to widen it and I tempted her out with some banana. We then set about stuffing any gaps we could find with socks. I seriously doubt she will find a way in now...but I've said that before. I've learned you should never underestimate a possum!
