Thank you for seeking help for your pet when your gut told you something was wrong. And a huge thank you for being open-minded to the suggestions you've received. The folks on here truly only want the best for the animals. It's pretty clear that Pretzel has a caring owner, and I'm sure that will translate to a healthy scaly friend.
I hope you stick around. I've been on this forum for months, and I swear I learn something new about these critters almost every day.
