Between one to two months ago, the ferret food was kept in a sealed container in the garage. At one time, we kept dog food outside with no problem that I know of. Recently, found white spots on some of the food. Does this mean the food is spoiled, or possibly got frost bite? This is the first time a white spot has appeared on this food. Could someone tell me what this might be, and should I even keep the food? fuzzybutts [Posted in FML issue 2987]
