As I understand it, the food grade stuff doesn't have chemicals and it's safe for mammals at least to ingest--they put it in food as a preservative, etc (Health nuts like it too). I was a bit concerned about using it in the cage since it's breathing, etc. and reptiles tend to be more sensitive than mammals to such issues. But if someone could guarantee it safe 100%, then I'd like to use it below the current bedding... as no one can, I'll have to use it around and under the cages. (Most of my friends are freaked out by snakes... TT)
Thanks. If anyone can say positive or negative wither way, I'd like to know. Again, food grade stuff only.
