Thanks, i agree we need more on the other side. It loves to curl up on the leaves to sleep and at night climbs around the glass side.
We use the stick on thermometer to measure the humidity and the black wire in the pic is the digital thermometer. I put it by Rexy and got a bit of a shock, it reads 14.3 but it seems to like it there! It's amazing how the markings can completely disappear sometimes, it can sometimes look the same colour as the vine (you can just about see him in the big pic).
The skull was my son's idea!
Off to try out the plastic & kitchen roll idea.
