My 6 month old male hognose seems to always be trying to get out of his viv. He keeps sort of standing up and pressing himself against the sides as if he's trying to find a way out. The viv is the right size and temperature and he has plenty of hides, so I'm just wondering if there's anything else that might be making him unhappy? Obviously I don't know if he does this when I'm not there, but he usually starts up just after I get home from work and keeps doing it for several hours before he decides to "go to bed"!
