I'm sure he enjoys the moss and feeling the "closeness" with moss in the hide. And partly I think snakes also enjoy the natural "plant fragrance" that moss has. Misting it now & then- not overkill- shouldn't hurt anything, at least I hope not. Just wanted to clarify that it's not something I've been doing with mine, so I can't "promise". Deserts just aren't humid, normally. But I'm not one to say "it's my way or the highway" either, lol. I think this TP is in good hands w/ you & I hope you enjoy him as much as I enjoy mine.
