One of our forum members mentioned that he feeds DE to his torts to help control worms/parasites. I had never heard of this and went searching on the internet. I have been using it with success to kill ants in my leopards enclosure. It was a surprise to me that people not only feed it to their pets, but they also eat it themselves. I would really like to hear comments from other members if they use this and what experience they have had with feeding it to their torts. Opinions requested too.
