Hi I joined this forum specifically to ask this question since I couldn't find any info online... So sorry if I make mistakes on here or use it incorrectly... I'm new :^P

Onto my problem... I have a male ball python. I've had him for a little over 2 years and he's only refused to eat 2 or 3 times ever and always ate the next week. I feed him small frozen rats currently since those are he best size for him. He's never encountered a live rat or mouse and is content with frozen. He eats once a week or sometimes a week plus a few days. Last month I went to a camp for 2 weeks. He ate when I fed him before I left but when my parents tried to feed him he refused. They tried multiple times. When I got home I tried to feed him and he immediately ate. He 2 weeks in a row for me... But I'm not in the house anymore. I'm going to school and I'm in a dorm where I can't keep him. My parents are taking care of him. They know his care routine and everything. But I've been gone for 3 weeks and he's been refusing to eat again. I've never heard of a situation like this before. I've always heard snake's don't have the capacity for emotions beyond really just fear. Is there any way he's upset because I'm not the one feeding him? Is it a coincidence? I don't want him to starve. I know they can fast for a long time but he's never fasted for more than a week for me. He hasn't lost weight yet but if he keeps going like this... I'm worried about him. Does anyone have any advice? I'm going to be gone for 2 years. I'll be back on breaks and probably about once a month. I haven't visited home yet so I'll have to test it when I get to visit.

As for more info about him... I don't have much info about his background because he's a pet store snake (I'm sorry I know it's bad.) He's probably between 2 and 3 years old. He has a nice large tank (sorry don't know exact dimensions) and his set up is pretty nice. He has a warm side and a cold side with an identical hide on each. The cold side is also the wetter side with a cool mist humidifier sometimes turned on and a water bowl. His substrate is coconut fiber and he has a strange obsession with trying to dig tunnels so I have it decently built up (for some reason he isn't satisfies with only having one exit in his hides.) He has an uth as well as lights on the hot side (His tank actually is supposed to be a fish tank. it has good ground space it's very deep so I use the light to keep it warm enough throughout all the air) On the inside bottom of the tank under the substrate there's a terrarium liner so that if he burrows he won't touch the glass and burn. He has a few fake plants because he likes to climb as well as a safe piece of driftwood in the center of his tank. Nothing has been changed recently. He's been healthy the whole time I've had him. He's never had any sickness or mites or anything and he's always eaten well.

Thank you for your help! If you need any more info about him please ask! I really need advice
