Well, I think your temps are a little low. They should be more like 90-92 on the hot side, and 80-82 on the cool side. What do you measure with? Do you have a regulated UTH? I don't think it would be enough to make him stop eating though.

I would recommend feeding inside the enclosure. There really is no advantage to the snake moving him to feed. Ball Pythons stress really easily, and not all can be moved before feeding. I have some I can't even handle on feeding day.

Your post says he's active? Active means a stressed ball python. He should hide all day, and a lot at night as well. What kind of hides do you have for him?

It's also still coming out of breeding season for these guys, and most will fast. Since you just had snow recently i'm guessing he's still in winter mode. You could try a live mouse to bring him out, but he might imprint on them. I would give him another month and try a mouse. They are stronger scented, so might be able to bring him out of the fast quicker.

The brightness of the room could be stressing him out too. Do you feed during the day or night?
