So my 500~ gram boy hasn't eaten regularly since last September. Figuring he was off for the breeding season and since he wasn't losing any weight, I didn't worry too much. He continued to eat after his sheds but not any other time. He shed last night so I offered prey and he refused, jerking away and obviously not interested at all (no tongue flickering, not even looking at it). It was F/T but it was warm enough (Vestris took a prey item of nearly the same size just fine). He hasn't lost much weight at all (and has actually gained weight by about 40 grams since September just from the meals he's been taking after shedding) but the breeding season is almost over (right?) and it's been 10 months now without eating solid. I've tried live and F/T mice and rats and he hasn't seemed interested at all. There is nowhere around here to get ASFs. He's long and thin, but hasn't noticeably lost any body mass. Is there anything I can do besides wait him out? The thought of braining a F/T prey item makes me queasy but I could probably do it. Would a parasite make him not interested in eating but also not make him lose any weight?

He also had a really weird elimination which is what spurred my making this post. I haven't seen anything like this come out of him before and I honestly didn't think he had anything left in him after 3 months without food since his last shed. It sure looks like parasites to my untrained eye... (Link because it's kinda gross)
