Here is one I have never come across, lol. Oscar my sulcata, is now in the house pretty much for the rest of winter, so, for the next six months or so. I just hooked him up a new Mega Ray, now the question I have is, he wears Depends diapers. Do you think I should take them off and lock him in his room for a couple of hours throughout the day so he can bask under his lamp? I am not sure the uvb will penetrate through Depends, if I had to guess I would say no. He cannot free roam my house without diapers because he does gross disgusting things to inatimate objects in my house. He also traumatizes the kids, and myself, lol, when he drags around his "stuff". So the option of no diaper, is not an option. I know he will have a fit if he is not allowed to wander wherever he wants, whenever he wants. So what is your opinion on the diaper and the uvb penetrating through it?
