I heard that there is food grade DE and a different type of DE that is
used for pools. The one used for pools should not be used for animal
ingestion for parasite control.
The group that I learned this at is www.yahoo.com click on Groups and
join NaturalHorseandPetCare. Other great groups that I belong to for
ferrets is: ferrethealth, NaturalFerrets and homeopathicferret.
