Does he look underweight?

Nice that case id just feed him the size he enjoys and wait for the weight to come back, rats helped my guys weight issues. But I'm no expert someone could come and say I'm wrong but if its just underweight a tad with no underlying illness or something like that it should start coming back. Either way if I'm wrong or right I wish you all the luck in the world with your little guy

What concerns me about this snake is how MUCH weight it's lost. If its that young why did it lose so much weight? Does it have parasites? Has it been regurging? If you got it from a pet store, I'd be looking into health issues for sure.

Also It must have been a rapid weight loss in order for his spine to stick out so much. The wrinkling is probably exacerbated by the fact he's in she's, but it looks more like weight loss wrinkling than dry skin wrinkling. Keep a very close eye!

After a couple of rat fuzzies I'd up his prey size for sure. Or even double up on fuzzies
