Interesting article, if my snake isn't showing affection or love then he sure is showing respect for his care taker. I can assure you that my snake is not stressed out at all as he eats fine and seems perfectly healthy. When I take him out he seems to enjoy his time out and when I put him back he just "smushes" on the front glass like he wants to come out for more missions. To me that says having 3 hours out doesn't stress him out because after I put him back he just wants out for more. I gradually gave him more and more missions as he grew up so it's not like he started off getting 3 hours out a day, I know that would probably stress out a young snake but he grew into getting more and more over a 5 year period.
