Care for your furry loved-ones organically with the DiatomaceousEarth Food Grade Flea & Tick Powder for Cats & Dogs. Diatomaceous earth, or DE for short, is one of nature’s greatest solutions for all-around pet health. Just add a teaspoon of DE to your pet’s food each day to see the benefits. Consistent dosage can result in an improved coat, appetite, metabolism and digestion. And it’s also great for the litter box too, working to absorb moisture and eliminate smells. Plus, it will never expire if properly stored, so you can use it for a long time to come.
