I dont know about an issue, or not. Like previously stated they are from Yemen and that is a real desert environment where temps can consistantly reach over a hundred degrees. Actually, the summer days will rarely drop below hundred. I know when I was stationed In the middle east it was rare that the temp drop below 110 in the summer, it was actually easily 118 or 120 at times. You would probably have to consider the thermometers I was going off of where ones hanging on the wall that could have b3en there for no telling how long, but I sure they couldnt have been to far off because they all read about the same. I believe the reason people keep their basking sites at the temps we know is because one: it gets the job done and keeps them healthy. Two: It is safer because it is a little sketchy trying to get those high temps without burning your cham.So I believe we settle on these temps since they do in fact do a good job, but I dont feel like it is anything out of the ordinary for veileds to experience these higher temps. I know that at times the temps in my house change and I will find the basking site will be at 105 and my guy is just hangingout basking and doing just fine. I think he is just fine but it might be a good idea to monitor him as much as possible so he doesnt burn, or maybe lower it a tad just to be safe, but I thi nk he is perfectly fine and nothing to worry about!
