I GOT IT OFF!!!
Thank you VERY much for all your replies! I knew oil with a q-tip was the best option, but I truly was worried she wouldn't let me or it would be so stuck I wouldn't be able to do it.
But WHAT A GOOD BABY. She never once hissed, struck, or even pulled away sharply! She was SO patient! Sometimes I think we don't give our animals enough credit. I really think she knew I was trying to help her. The tape did pull away the very outer "layer" of the scales - almost like a piece of shed - but the scales themselves do not appear damaged and there was no tearing of her skin.
Needless to say, I have her in a lockable enclosure now......
Thanks again all!!
