I also mist my hands before I handle my White's Tree Frog. He seems to like that better compared to me not misting them, and my hands don't seem as dry after he is put away either.
1: Try not to abbreviate. Especialy White's Tree Frog. <_< >_>
2: I'm not sure I understand when it is and isn't safe to use distilled water. Sorry for all the questions but, could someone clerify?
