The blog I read said something about it only being within the last week if I read it correctly. Still, I am tripping about this, I mean I change food to avoid wheat gluten in the Pro Plan and now I might be endangering my cats still because of something bad in the new food? Comeon, I can't deal with this. Everytime I open a can or bag of food I feel like I'm playing a sick game of Russian Roulette with my cats lives. What can I feed my cats without putting them in danger?
