Yeah it is so obvious to me that it’s not necessary for healthy animals for exactly this reason. Yet when I posted on r/ballpthons that the benefits of UVB are disputed and that many many balls have been kept without it for years with no ill effects, my comment was removed for being wrong or offering dangerous advice! I’ve done some research on this issue and so far have decided that it seems worth providing but I definitely take your points about the fact that it must not be necessary otherwise all those no uvb snakes would be dead. And that lighting provision is multifactorial and we may not be providing the benefit we think we are. I’ll def continue to do research on this topic!
