I wouldn't call it stress per se. I have all of my snakes in a rack setup so the temps etc.. are all the same, but I still have a couple of snakes, my male pastel and spider specifically that always seem to be out zooming around and checking corners etc... I just take it as part of their personality and not as anything negative. I've found them to be my most voracious eaters also, anyone else find this with their more active bps?
