Hi, I am wondering if a Greek Ibera could have gone into hibernation at 5 months when daytime temps are still 90F and nighttime around 55F. His routine did not vary in the days preceding his disappearance, as he still ate and I didn't notice any digging. His outdoor enclosure seemed undisturbed (chicken wire lids still in place and he could not have tunneled out). There are no locks on the lids, so I'm down to it being stolen or suddenly hibernating. I'm new to this, so I was expecting him to slow down and then I was going to bring him inside. I dug around in his usual spots and after 3 days, he still has not appeared. Any thoughts?
