I bought this DE at the farm supply to feed my chickens and put down in their coop....and have done so. But now, I'm wondering if it is the safe kind. It says: Silicon Dioxide 85%, other element oxides 10%. I even put it all over my dogs, and in their kennel. Am I killing my pets? Please help? This DE issue is soooo confusing. I thought with it being organic....it would be safe!! It says insect dust. Help?!!
