Hi - haven't posted in a while, but I'm going to start putting together some custom cage furniture for my bearded dragon so that he has more places to climb, different levels to bask, etc. and I had a few questions. I'm not the most handy person so I'm sorry if some of the questions seem a little silly or obvious. First - what is the proper way to make a retes stack? I've seen them made all different ways - with the diagonal pieces in the middle, with just straight levels, with holes through the middle, with thicker and thinner wood, etc etc. What's the best way to do it so that it works the best for allowing varied temps for thermoregulation? I've searched online and I haven't really found a definitive "best" way to make them. The other thing I wanted to ask was what are reptile-safe materials to make cage furniture? I want to make sure anything I use is safe. Is there a certain type of wood that's better to use? Do I have to seal all the wood pieces (like the stack)? For fake rocks and such I've gathered that polystyrene and grout are okay to use, sealed with polycrylic? I just want to be triple sure that anything I put in his enclosure is safe. If you have any other tips to throw out there for this kind of thing, go right ahead. Like I said I'm not the most crafty person and I don't usually do stuff like this so I could use all the help I can get, lol. Thanks!
