I am so saddened and disheartened to learn that my best friend, JT, a Jackson's chameleon is on the brink of death due to metabolic bone disease. I am confused because the vet told us yesterday that he looked better than most chameleons he sees and it is in the early stages of the disease. He recommended using a Power Sol light bulb, which emits UVA and UVB. Everything we have previously read about on this forum recommends bulbs that emit UVB. Who knew about the need for UVA? I haven't seen it posted here, but regardless, I blame myself for JT's suffering and end of life condition. I just pray that he won't suffer any more. He has spent the past two days collapsed in his enclosure. We took him to the vet yesterday, and he gave him a shot in his swollen leg with Vitamin A, D, and Baytril (?) antibiotic. JT is so weak and lethargic that he can barely lift his head. We were told to force feed him some crickets today. It was terrible. He resisted as much as he could, but he never even hissed or tried to bite us. This is the sweetest chameleon we have ever owned. Is it my fault for not knowing about the need for UVA? I totally blame myself. My husband said we didn't know, but how could we miss this? I just hate to see him suffer. I can't bare the thought of losing him, but I feel even more strongly about not having him suffer. His leg is huge. The vet said this is not uncommon, but he said the lethargy today is not good. Does anyone know if all chameleons should have UVA and UVB lighting? It makes sense, though, since they would have exposure to both in the wild. I am beyond distraught as I feel like I have contributed to the demise of my best friend, which is unbearable. I don't know what's wrong with me, but I am so attached to this little guy that I am having a hard time functioning. I wish I could take on his pain and suffering so he wouldn't have to go through it. If anyone has any words of wisdom, they would be greatly appreciated.
