hand misting is fine especially for just one enclosure. I purchased one of those 2-gallon sprayers and go enclosure to enclosure because I have more than one... my hand would get tired hand-pumping for all.
Nope... maybe if it were night-time when they are active and not mostly asleep, and I allowed the baby to walk in front of him, or walked away without monitoring them. They're a very slow moving species.
