I have emailed Mazuri, a part of Purina Foods, twice now within a 3 week period and they have not even responded to my question about my concern of the Ethoxiquin ingredient used as a preservative. All I know is that I have stopped using it completely because they have not even acknowedged my emails. Very Poor Customer Service!!! Eleanor and the 7 fuzzbutts [Posted in FML issue 5176]
