I have a herp vet down the street. I don't have a reptile specialty store for roughly 80 miles. Go ahead and ask them, or give me an email address, I'd be happy to send them an email. This post had started with my concern on the amount of substrate my snake was ingesting, and snowballed into a much bigger argument.
If you don't like the level of concern I have over my snake, then don't read my posts, and don't comment.
A lot of new snake owners have the same concerns, which is why I post things like this. And it's people like you, who think they know everything about everything, that make me feel bad for the people on this site who legitimately have concerns for their snakes.
