I guess I still don't see how it's over reacting to contact a manufacturer to make sure your feed is ok. I posted my responses to help ease other people's minds as I have received good confirmation that Mazuri is A-OK.

How else should we have acted? Waiting for them to tell us it's okay without us taking any action to get the answer? We needed answers, and we got them. Simple

As a matter of fact, I think they handled this really well.
