The small gap he went through first wasnt in his enclosure but the gap he got through in the enclosure was only 10mm! smaller than the first, and was for ventilation, can you believe it! he is about the size of a 50cent coin at his fattest part. Have been looking for him everywhere and have turned the house upside down, i do hourly patrols with a torch at night and have set up some bottle traps with some pinkies around the house, the roof will be my next misson this weekend if he doesnt turn up.
