I know you're trying to help, & I'm glad that seemed to work for you, but I think that might be a bad idea for several reasons:
The OP already has qualified veterinary help on board, which IMO is way better than a method spread on the internet by non-vets & without serious objective medical & scientific testing. (I know that some claim that nebulizing F10 has worked for them, but we don't have combined statistics for all those that it didn't work for, & some recoveries may have been coincidental. And since the product labeling spells out it's toxicity to living things, I'd personally want more to go on than internet claims, or the claims of people that are in big business selling snakes & for whom snakes are merely merchandise, not personal pets.)
A Western hognose is a small snake from a dry climate, as opposed to a much larger snake from a more humid climate. Do you see a potential problem with this? I do.
