I draw the line at doing things that are clearly impractical. For my rattlesnakes, i'm not exactly going to ship in sand from the US am i. Sand is sand at the end of the day.
I know they aren't in the news paper, but some how they've got into his collection.
If you use natural substrate its not hard to eliminate the chance of mites being present. I freeze, and then bake and micro wave all my substrate to make sure anything in there is killed.
To be honest, i couldn't care less if people accept it or not. People are set in their ways, and me coming on here without scientific backing isn't going to change that. But because there isn't evidence for it, doesn't give me reason to just provide my snakes with the basic environment does it? We shouldn't just assume because they are eating etc on paper towels they wouldn't benefit from a more interactive enclosure.
