He's been fine thus far, I haven't messed with him and he hasn't reacted like he was. I got a price for the fecal and am currently waiting for him to eliminate in order to bring it up to the vet. As far as how experienced the vet is with reptiles? I can't say. There aren't many exotic vets around here for me to be picky with. If I need anything more than the fecal I'm going to look around though. I've had great experiences with the cats and dogs I've brought there. My normal vet got her own practice in another state (she was an exotic vet too, though I never had to see her for one) and I've been bouncing around between all the different ones there since. They're not as good as her, but it's better than nothing.
If nothing shows up on the fecal, I'm going to wait a couple months and see if his behavior changes. Maybe it really is because of the snakes I'm babysitting or breeding season or something. I'm going to leave him be for a while though, I don't want to stress him out and make matters worse.
Thank you all for all your help. I'll keep you posted on the fecal results.
