The real shocker, of course, is the scope of the list... one hopefully already knows, or suspects anyway, that Win-Dixie, White Rose and Key Food brands might be bad, but low-nitrogen foods like Eukanuba and Science Diet? Well now you know.
And bear in mind that Iams is made by Proctor & Gamble, the industry giant that still conducts tests on live animals and has been known to keep those test animals in hellish conditions. And that includes animals at their "test kitchens" for pet foods.
A safer and more humane choice would be the smaller purveyors of nutritionally sound foods. Ask your vet or small, independent pet food store.
