We suggest storing your kibble in the original bag of which most now come with zip-lock closures. You may of course place it in another container if desirable. If the kibble is transferred to another container please wash the container and thoroughly dry before placing new contents. Some of the fat that coats the kibble can coat the side of the container and over time may turn rancid if not cleaned regularly. This can make your pet turn their nose up at the food! Store the product in a cool DRY location.
