As far as I'm concerned, the issue with ethoxyiquin is conjecture, not fact. I believe Bill Gruber did a literature search on it and did not find anything (is that right, Bill?). Also, this question has been put to Dr. Lenny Southam, who is the veterinary manager of CompuServe's Pets/Animal Forum, and she said she had no scientific studies showing adverse effects. Until I hear otherwise, I will continue to use Science Diet. Avoiding preservatives is a matter of personal choice, IMO.
