Nakoa Update 2

[Bogertophis]

So sorry to hear he's still not doing very well. If he's eating dead prey, have you tried adding digestive enzymes to his food? (Best way is to push them into the oral cavity- aka mouth- of the rodent so the snake doesn't smell anything different & have any reason to reject the meal.) It makes some sense to me that his digestion would be poor if he's underweight, because production of digestive enzymes requires good nutrition, so it's a vicious circle.

Can I assume you also tried giving him probiotics in his meals? (I had to go refresh my memory with your earlier thread about Nakoa.)

Regurgitation is certainly a big concern though & without knowing what your vet has tested for, nor what other treatments he may already have had, I don't know what else to suggest. It could be something like crypto that's slow to show up, I suppose? If it's crypto, there's clearly not much you can do, so I hope that's not it. And your vet has a point- we can't "win" them all & maybe you need to focus on your own issues & "the big picture" now? Sick snakes can be so tough to deal with- they don't always give us enough clues.

He might also just have some sort of stricture in his digestive tract- a "birth defect" that limits his capacity to eat enough & grow properly, in which I'd personally opt for euthanasia- not surgical intervention. -Assuming you could find someone skilled & willing, because it would still mean too much suffering for the snake, IMO.
