Question regarding my snake?

its normal for some snakes. Don't worry. If its cold, it will move to a warmer spot. And if you're that worried (sometimes if freak because i think my snake is missing when its just hiding...) then buy a hubble or log or something it can use for cover. I've got a rat snake and he does the same thing even though he's got his log. I think he does it to mock me because i named him Ninja.
