Is DE (pool grade) safe for cats?
My mother has a fully enclosed cat run (includes a top).
The cats are allowed to spend time in there supervised.
She is concerned about fleas and doesn’t use flea preventative chemicals on the cats nor in the yard. She would like to spread a thin dusting if DE in the run, to aid in flea control.

If the cat area has a soil floor and is open on all sides (so that it gets rained on) she would probably do better using beneficial nematodes. These benign microscopic creatures will prevent any fleas from developing in the yard (wherever they are spread) and are totally harmless.

In general, pool-grade DE is not safe for inhalation by any mammal. For indoor flea control use a DE or boric acid-based product designed for fleas, e.g. [url]http://www.fleabuster.com/Products/RxforFleas2.html[/url].
