Welp... I've never even heard of Diamond...I feed my cat mostly Western Family.
Oh and Diamond has a manufacturing facility in Lathrop, California. Just because your state isn't on the list doesn't mean that Diamond doesn't sell in your area... There's many places that sell Diamond foods in my area (I checked). 2 places in Tacoma apperantly sells Diamond...I've been to both of em.
Go here to find the closest place to ya...so you can then ignore it...
