They say blankets are bad for cold blooded animals since they're meant to reflect the heat that a body produces and cold blooded animals dont produce any heat. So why does my dragon, and I assume others as well, run absolutely wild when they dont have a blanket to be under? Or in the case of mine socks, blankets, shirts, pants, hats, and if she can them she WILL try to hide under your body all together lol ... but otherwise just goes for the materials.
