Product Questions and Ingredients

Feeding Guidance

Product Quality, Packaging, or Foreign Material Concerns
If you believe an IAMS product has a quality problem, packaging defect, unusual smell, damaged bag, mold, foreign material, or other safety concern, stop using the product and contact IAMS directly. Keep the package, UPC, lot code, best-by date, store receipt, photos, and any remaining product until IAMS or your veterinarian advises you what to do next.
Retailer Orders, Shipping, Returns, and Refunds
If you purchased IAMS through a retailer such as Chewy, Petco, Kroger, Amazon, Walmart, Target, a grocery store, or a local pet store, order cancellations, delivery issues, damaged shipments, returns, refunds, and subscriptions may need to be handled by that retailer. Contact IAMS for product questions and contact the retailer for order-specific support.
