500 gram male off feed for 10 months... really starting to get worried now.

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)

Eeeesh. Looks like it's time for a fecal. Weird that he hasn't been losing any weight though... Maybe he just wasn't hungry before, but there's a parasite in play more recently? If last night was the first post-shed meal he's refused. Does that make sense?

i was going to say that if your husbandry was spot on and he wasn't losing any weight to not worry about it too much.. then i clicked on the picture. lol doesn't look quite right. i'd be on the safe side and go get a fecal done at the vet. fecals shouldn't cost that much, but as for the medicine usually used to treat parasites in snakes (if that's what it is), i have no idea.

is it CB or CF ?
If it's CF it's possible it needs treated for worms, I had a similar problem a couple years ago with a CF girl when she was about a yr old.

A fecal sounds like a good idea. Even CB animals can get parasites....

I didn't notice it before this time. And yes, this is the first post-shed meal he's missed while being off shed. Should I take him out of the rack he's in? Separate him from the other two I have, in other words? I can bag what just came out, should I stick it in the fridge until I can get him to a vet or just leave it out? He's from Petsmart so I honestly have no idea if he's CB or not, but I've had him for more than a year. Last time he shed was in March I believe. I can take a pic of his cards when I get home later.

Here are his cards. Not every shed had been marked but you can safely assume that when you see a check mark next to a weight, he shed before that. You can also see why I wasn't super worried about him having parasites in the first place because he hasn't been losing weight.

The fecal came back negative for eggs. The vet is pretty perplexed, she said she would find out more information for me. She thought it might be something sloughed off from his intestines or it was in the papers he was kept in (which seems unlikely in the extreme to me). She thought if she could find out what was going on that she would have me de-worm the three I have at my house. In any case, I won't find out more until Monday at the earliest.
