Update:
The fenbendazole made no significant improvement. She prescribed some baytril, which I had hoped I wouldn't have to deal with. He's willingly eating treats(as long as it's not directly after a feeding) now, but after the baytril I know he won't be. I'm waiting until tomorrow to start him on it, as I want to have enough time to monitor him after the first dose or two.
He's also still on simethicone and probiotics.
His molars have grown a bit since this started(I'm assuming because he's not chewing as much now that I'm hand feeding), but it's nothing that needs immediate attention and he can deal with that on his own if he starts eating soon... If not, he's going to need them filed.
What I have noticed recently is that he will eat a little bit during the night if I cut back his last feeding. Not enough for it to matter, but it's something. If I feed him too late, he doesn't touch his pellets at all. His weight is still stable at this point, slowly climbing back up.
Quick question: I've started my externship so I've been spending more time at work than usual. This conflicts with his feedings and medication times. Would the stress be too much if I bring him in more often? Temperatures will be controlled, so that's not an issue. With how I'm working, it's difficult to get his meds into him at the desired time, plus I can feed him more often to help put more weight on him.
If taking him so often(not necessarily every day, but more often than I want to) would do more harm than good... Would an hour or two early, or later be best for the baytril? He's supposed to get .2ml every 12 hours. He seemed a bit brighter on the sulfatrimeth(though it didn't solve the issue) so I'm hoping an antibiotic is the way to go. He's his same old self, just not eating. >.<
