I've heard of a lot of lizard owners (bearded dragons and another type of lizard whose species i can't remember for the life of me) using white millet seed as substrate, I was wondering what snake owners thought of this as well.
For those of you who don't know what white millet seed is or what it looks like, here is a picture i found on google search http://nutshell.ws/db4/00307/nutshel...ite_millet.jpg
