Hi, I'm still on my first reptile. Bowser is a ball python that just turned 1 in July. Currently he's in a 10 gal. viv which he is just slightly starting to outgrow. I asked my brother in law if he would help me build a new enclosure for him sometime in the near future, and being the handyman that he is, he's coming up with all sorts of ideas for it. Before we get into too much planning I was just wanting to make sure that nothing we build this out of can hurt Bowser in any way. We've planned a 4x2x2 wooden enclosure with two plexiglass front frames and 2 lifting lids with a latch on each one and a mesh screen on it. We're going to put a hole in each side of the enclosure from the back just big enough to fit a heating fixture through. And sections so that I can change the size of his side of the enclosure so that it's not too big until he grows some more. My questions are; 1. should i put a safety screen around the ceramic heaters that i put through so that he can't get to them? And 2. What sort of materials should i stick to so that it will keep him safely inside, but not hurt him in any way (I've heard many people say materials that snakes shouldn't be kept around for allergic/safety reasons, but never a definitive list of what I can or can't use). Also if you have any suggestions I'm open to anything. I just want Bowser to be safe and happy in his new home once it's finished.
