Still don't understand how you see no risk. There is a chance, though limited. He has much invested into his colony, he doesn't want to take a risk, and informs others to watch their own rats for sickness or death.

These two circumstances may be totally unrelated, regardless, he just bought mazuri, and some of his rats are dead.

You may not be able to affirmatively draw the connections based on what little data he has presented, but you cannot just dismiss it either. That's what I personally have been saying this whole time.

We aren't inciting riots, we didnt even say Purina's whole chow line is condemned and tainted, but I think the closeness of the two incidents, and the parent company for both being Purina, there is enough to go on to limit or supervise the rats closer than normal.

It's all under investigation to find out what the cause is, but it sounds like your trying to dissuade people from having concerns. It's OK to have concerns about your feed. It's OK to tell others to monitor their own animals. All this thread has ever been was a big concerning note to others.
