I would allow an extra week at least, for sure, before feeding again. He might just go into a shed cycle after this anyway. Wouldn't surprise me a bit...
Regurges are best avoided...waste of food and your $, but really hard on the snake, not to mention it smells like the "underworld", lol. Always better to error on the

BTW, to answer your original question, noseplugs would be handy...![]()
