Yep, I'm doing that! I spray 2-3 times a day for my BPs when they're about to shed, becuase I live in Colorado and it's stupid dry. I'm very conscious of it because I'm originally from Texas, and I figure if I'm uncomfortable and I'm NOT trying to shed my entire skin, they're even more uncomfortable.
My general rule is to spray tanks every time I put on hand lotion, lol. The BP girls don't mind much, but poor Totoro, he HATES the sky water!
