Diatomaceous Earth Food Grade 2.5lb

Really works too. I use it to deworm the outdoor cats and it is working because they appear to have filled out. Packaging could use some protection because mine had a teeny-tiny hole which caused some of the powder to spill out.

Dusting my dog's food with 1 tsp *unbaked* DE for 3 years now to prevent worms. Note, if you use swimming pool DE your dog could bleed to death because that product is baked.

Mixed it in their feed. Works well.

Seems to be good quality. Bag had two small holes in it when it arrived.
