It would probably be easier to start a new thread on your snakes RI. It does in fact sound like a serious RI. They will never throw up, unless it was a meal, but calcium urates could be yellow brown/white. And if he has mucus in his mouth and is wheezing he needs to go to the vet and quarantined immediatly. I don't want to hijack this thread but another serious syptom is the vertical head holding. This is a sign of either an ri or it's called stargazing and is a sign of IBD. Start a new thread and you will get more advice from more members on their opinions. But I suggest getting him into a vet and qt him asap.
