That actually happened a while ago. Go! Natural has done a recall and paid the owners for emotional distress, and apologized to the public. It was 7 cats and dogs all together that died, but they still haven't found any reason to believe that Go! Natural caused the deaths, and are still doing testing on the foods. The last I heard, they hadn't found anything wrong with the food. I fed Sara Go! Natural and never had any problems with it. I still believe it is a great food.
