Okay guys. I figured I would nip this before any rumors got started. I just got off the phone with Janis Gianforte of the Nutri-pet company which makes Nupro, and I have permission to qoute her. Each batch of Nupro is made from freshly shipped natural ingredients. Each ingredient is checked, doubled checked and physically tasted before mixing. If you read the label you know they use no artifical perservatives, flavorings or colors. These ingredients *would* have made each batch totally identical. Because of THAT fact, there may be slight variations to color or flavor during different seasons of the year. Janis used the example that if you read the label on a bottle of the Snapples all natural drinks, it says on there that there may be variations due to seasons as well. She assures me that no batches have ever gone out which did not meet their personal requirements. For those who don't know.... Nutri-pet is a small private business, not a huge factory.... they are very caring and serious people about their products and will stand behind them 100%. She also said that if anyone is still worried or would like to ask them about it themselves, you are more than welcome to contact them and they will be happy to address any concerns.
