She looks okay to me, if her appetite is good and she's doing well activity-wise I wouldn't worry too much. Just like Cooper said, she will get a good amount of
hydration from the greens and gutloaded bugs. The pictures are a little fuzzy so it's hard to see her head.
Did you take her in to be seen at Petco or just tell them you've never seen her drink?
Both of my babies rarely lick the water off of their nose and never drink from their baths, and they are not dehydrated at all. I spray them both daily, most of the time I get an indignant look and they back away and sometimes they will lick a few drops and that's it.
Usually when they're dehydrated their appetite stalls, if that helps you feel better.
