Great to know! Maybe I could use it on my cats.
Yes! We use it on all of our pets and livestock animals: cats, dogs, pet mice, goats, rabbits, pigs, chickens
Here is a quote from an authority on the safety of breathing DE:
I received an email from Larry Smith, the President of Earthworks, who wanted to clear up the misconception about any dangers of inhaling food grade diatomaceous earth – here’s what he wrote: ‘This is a misunderstanding about food grade DE. There are 2 kinds of DE—food grade and filter grade (used in swimming pool and other filters) Only the filter grade is dangerous to breathe. The “dangerous” part of DE is the amount of crystalline silica that is in it. Filter grade is 65% crystalline silica while food grade is less than 1/10 of 1%! The world health org. has said that diatomaceous earth is safe to breathe as long as the crystalline content is under 2%. Food grade is 20X lower than even that level!!’
So no need to be concerned about any danger associated with using DE for pets, bedding, consumption or anything else – as long as it’s FOOD GRADE! “

Here's a link for a great article on lots of the uses of Food Grade DE:
The Beginner's Guide To Diatomaceous Earth This includes a video on how to use DE for fleas.
By the way, you can pay about $3 a pound for a bag of the Food Grade DE for people ($28 for 10# on Amazon)....or get it for about $1 a pound in a 50# bag (of the same thing) from an animal feed supplier. I get mine off of Ebay (I took a screen shot of the exact item--best deal I can find: $69 for 50# and free shipping!) At that price, I can afford to use DE internally, on fur, on carpets, in boxes, etc. etc. etc. We even mix it with water to spray on the wood of our hutches to help "sanitize" when we want to move a new rabbit in. Works on bacteria, viruses, fungi, parasites, odors, etc.
Hope this info is helpful! It comes from lots of (painful) experience and lots of research!!! ;-)
God bless you! (And, thanks be to God for such an effective and safe remedy!)
