I searched online what it could mean, and many say it can indicate your Bearded Dragon's mood. My question is if my Bearded Dragon is happy or stressed. I want to make my Bearded Dragon comfortable (she is already full-grown since I've had her for a few years), so I need to know if she is feeling good or bad when her tail shakes like that. Her tails sometimes shakes when I put her on the windowsill, since she likes to look out the view. I'm taking this as a good sign, but I start to wonder when I pet her and that happens, if she's really enjoying it or not. Thank you :)
