1 1/2 y/o ball python feeding behavior

[the-shiny-snek]

So my 1 1/2 y/o ball pythons feeding behavior has been weird lately and i'd like to get some opinions on it. I've had this snake since he was just a month old and i had barely any problems with him eating since then, but in the last 2 months his beavior regarding food has completely changed.

He used to almost immediately take the food off the tongs, I was always super proud of how easily he would go through his feeding sessions but then he suddenly wouldn't eat off the tongs anymore, he didn't display any signs a bp normally displays when food is around (the s-position of the neck, high alertness etc.), he barely showed any interest at all, so I started showing him the mouse and then laying it on his branch and he'd gently take the food into his mouth and eat it from there.

Okay, I thought, as long as he eats it shouldn't be a problem right? but then he stopped eating completely about three weeks ago. So i'm wondering since he's 1 1/2 now that he might have gone on a feeding strike bc it's still winter, even though that would be pretty late, but i can't explain it any other way.

i haven't changed his food, his feeding schedule, husbandry or anything else when those changes in his behavior started, so i'm honestly at a loss of knowledge rn. do any of you have any advise? should i go see a vet?

How much does he weigh? Is he going into shed?

i haven't weighed him in a while, so i can't say exactly, but he should be fine for his size, his spine is not showing prominently and he's also pretty sure not overweight. I also don't think he's going into shed, he had a fine one shortly before his behavior changed.

i should also say that the rest of his behavior hasn't changed at all, the only time where he behaves differently is during the feeding

Sounds like he is having some late season breeding blues
