Diatomaceous earth kills pests but you can feed it to animals??

Interesting tips I just found out!
You can sprinkle diatomaceous earth (food grade type) around your garden (wear a mask) and protect it from many pesky pets. While it is dusty and airborne..it is an irritant if you breathe it in (same for pets). But once it settles it is safe.
I also read that in studies on livestock and housepets that when mixed into wet or moist food at a about a 1% concentration that the Diatomaceous earth will pass through the system and kill any internal parasites.
This is not regulated or approved but seems to make sense read up more and decide for yourself!
