I lucked out. I fed a very few cans of gravy-based Iams to my dog and one cat. Neither have shown problems. And it turns out that Iams blew the whistle on Menu Foods, bless them.
That’s great. Our pets don’t eat much wet food, and the wet food they eat is usually Purina which wasn’t affected. I didn’t know it was IAMs that came out. It’s great that they did. If they hadn’t, it’s possible animals could have continued died and getting sick with no one to connect the dots.
