The RR food isn’t that bad. It’s got the synthetic vitamin K in it, which can be problematic over time, but in a rotation, I don’t see anything wrong with it. My guys love it.
As for Purina, I’ve used Pro Plan, Beyond, and Friskies (for the cat, obviously lol) with no problems. Beyond used to have the vitamin k in it, but I’ve not used it since the new formulas came out. Still looks like a decent food, but I don’t know if they still use that vitamin k or not. I wouldn’t use anything Purina for an extended period of time, but they do have some pretty good foods. I wouldn’t blame anyone for not wanting to use Purina products, but for me, price and coupons are a factor, so I get what I can lol
