I was wondering how you can tell if your snake is stressed out when you handle them. He is still young so I hold him maybe once to twice a week just to socialize him and check his enclosure. What are some signs that they are stressed? He doesn't curl up into a ball and doesn't really roam around, he just lays on my lap, and I usually have my heating blanket on so he chills on that on my lap, or goes inside of it with just his head peeking out.
