de-worms but if there bigger variety like 20lb bag maybe it get more stars...year round protection if use it like that...but six pound bag is nothing it mean you have go all way to like twenty four pounds to survive about three months. I don't know...depends how much you have already, in supplements. But it has minerals and dewormer on good scale this would be definitely good but details need to improve. The whole story about how its good should too. Like maybe if they made 24 lb bag or something. People would have buy at least four to attain that amount but six bags for 19.95 is not good deal. maybe if was like 24 lb bag at price 19.95 is good and understanding deal. People must compensate for those suffering the gas tax.
