I contacted Dave’s about a year ago and they wouldn’t disclose who they use to can their food. The last info I had was that they use several with Evanger’s being one of the co-packers.

Not sure about if Rx food would affect the other kitties. I wouldn’t want to feed an Rx food if they didn’t need it, but I know you have other considerations as well.
