Had I researched carefully before my poor beardie wouldn't be going through an obstruction in his bowels. But thankfully, after careful reading and finding out that the substrate I had in there for him was BAD for his health I quickly changed it to newspaper until I can make sure he's fully recovered and then I plan to start using shelf liners. Ignorance is not bliss and petstores are terrible. "oh this is GREAT for your bearded dragon!" -.-
