I am looking at building a cage for some beardies. I am planning to make it so that it can sit on top of my BP tub rack. This means the floor space dimensions will be ~36"x15 3/4". I am wondering what a good height would be. I am planning on using Melamine and the widest boards I have found at my home depot are 23 3/4". This would likely end up being the height. I am thinking of 2 beardies because a local shop that breeds them is doing BOGO Free. Would this be tall enough for them? I have seem people talk about melamine sheets but I can't find them at my home depots near by so I would have to come up with something else for the back and sides to make the height.
