I think due to the ridiculous cold that has hit much of the country, I see you're in NC and I believe it's been cold there too, a lot of us are having a little more difficulty with humidity than usual. I've added some sphangnum moss to my enclosures. It helps, but I'm still needing to mist the the pythons at least daily and the colubrids almost daily.

We might hit 50 here in MA today, nice break from the weeks of single digit and sub zero weather!!
