We used up the 3 pound package of Bentonite Clay in about 5 weeks at the Humane Society of Waupaca County! My boss was a little skeptical when I suggested using it, but it has far exceeded what we expected from it. I just ordered a 5 pound package. We use it for diarrhea cats of course, but we are also using it for puppies, for sick animals and also one that was injured by a car before it came to us. I made a poultice with it and it helped him heal much faster. We LOVE this product! Thank you so much.
