I am glad to hear that your beardie is doing better! I have been trying to get answers from all different sources as to the cause of this untimely death. I am FAR from being ready to get another one, but I would like to avoid this sorrow in the future. One source thought that the substrate I was using could have been the problem. I was using the calcium sand that is sold in most reptile stores. I guess they can't digest it and it becomes toxic to them? Any thoughts/ideas about this?
