Dust to Dust is completely non-toxic and plant-based. Therefore, it is safe to use with pets and will not cause harm. Please keep in mind that Dust to Dust is a fine silica powder. This means that it may irritate you or your pet if you breathe it in, directly. It may also cause irritation if your pet has sensitive skin. We recommend use on a pet's bedding, working it in and brushing off excess dust, to deal with fleas and other unwanted pests. We also recommend consulting your vet for any concerns you may have regarding your furry (or feathery) friend.
