Thank you, Donna, for posting this. As soon as I saw there was a problem with the Rice Protein concentrate in Natural Balance I e-mailed Blue Buffalo because I know that they have Rice Protein concentrate in their dry dog food. I e-mailed them a second time this morning, and have still not heard anything back from them. I also checked their website this morning and did not see anything on it. So although right now they may be talking about cat food, I appreciate the heads up. Also Zippy indicated that she feeds her cats Blue Buffalo. I will pm her and let her know about your thread. Thanks again.
