Okay, he didn't eat for the first time. I thought it was due to him getting ready to shed. However, that was Friday, and it is now Monday, and he has no other signs of shedding (considered his eyes getting cloudy on Friday). No pink belly, no skin coming off at the nose. I have raised the humidity in his tank using moss stuff from the reptile store. It keeps the humidity around 70 and above usually.
The next time I try to fed him will be on his regular day, Friday. Hopefully he will have shed by then, or he will eat. Or both of course.
