I received an email today from a Beverly Fischer at Purina. She informed me that the 5D05 is made in Richmond, IN, as well as Macon MS. From the information I provided to her, she believes my bag came from MS. She told me she was contacting their nutritionist, and would let me know what she found out. She apologized for taking so long to get back to me.
I would like to publicly thank Ms. Fischer for taking the time to respond, I greatly appreciate her efforts to assist me.
