4 Year Old Ball Python Stopped Eating

Hey guys! I have a 4 year old ball python that has always eaten like a dream. Every time I would bring the thawed frozen mouse into the room he would start pacing around the tank and flicking his tongue acting all interested and would eat immediately. For the past 6th months he has been living with my parents and eating weekly. I recently moved back home and when I went to feed him he stopped eating. Shortly after he went into shed. His skin just recently shed off and I attempted to feed him again today and he wasn't interested even though it has been 2 weeks since his last feeding.

Should I be concerned? Why do you guys think this is happening after years of easy feeding?

Thanks in advance for any help you can give me. :)

What's your husbandry like?
Has anything recently changed?

He could just not be too hungry yet. You say he just shed. Wait and offer again later.

Two weeks isn't really anything to worry over. Sometimes they just don't eat. As long as he's not losing weight it should be fine for a bit.
