Is this product safe for cats? (Used indoors)

Answer by Chewy • Apr 05, 2020
This product is safe for cats.

Is this safe for human consumption?

Answer by Chewy • Dec 07, 2020
This supplement is not intended for human consumption.

What is the differences between the bag & bottle? Also, how do you give this to your dog? I'm reading diff reviews so want to make sure before I buy this.

Answer by Chewy • Oct 29, 2020
The difference is the size. The bag is a 4 pound bag and the bottle is 8 ounces. This supplement is intended to be mixed into food.

Since there isn't a 'feeding instructions' tab, would you please give me an amount in regards to giving to my pet cat.

Answer by Chewy • Apr 16, 2021
Harris Food Grade Diatomaceous Earth is to be mixed in animal feeds in an amount not to exceed 2% by weight of total ration. Take the weight of the amount of food given daily x .02%. This will be the amount of Diatomaceous Earth to add to the food daily.

the little nightmare fuel bugs keep getting into my house so i sprinkled this in the area that i had seen a handful coming from consistently. it also had the bonus effect of keeping weeds from growing in that area too. not sure if this is how this product is meant to be used, but a win is win.

I love this stuff, its a multi purpose staple in my home. I use a little in my pets food container, I buy a months worth of kibble for indoor cats and dogs along with outdoor cats. I also use it in their litter box and a few times a month on my carpet. Great deodorizer and bug killer. Being food grade its not harmful to my fur babies.

Has helped eliminate fleas in the past and possible mange that my dog may have picked up in the yard. Just rubbed it on him, put in dog beds and throw rugs. Other dogs in the house didn't get it and my dog stopped itching. Took a few days to kick in.

We use it in the garden

We have indoor outdoor cats and use this as safe pest control. It works against ants and maybe even other bugs. But most importantly cats are not affected. Chewys
