Drats catnapper, I am so sorry you lost Nicki! What a shame! (Wish I had found that sooner, it might have saved your baby.)

I think ANY food in question should be pulled from the shelves immediately until it is proven it is safe. They do not know what they are looking for in the Nutro so they can not test for it. They just need to test every ingredient they use to make it for any unknown substance that is not suppose to be there... More ingredients from China maybe? Who knows.
