We bought some Purina Scratch for the first time yesterday. Previous purchases had been scratch compiled from our local mills or our own combination of 1/3 oats/ 1/3 wheat and 1/3 corn with a very very generous addition of sunflower seeds. We were shocked at the amount of corn in the Purina bag! No wonder it is considered a treat and minimal nutrition! We won't be buying it again, but darn it's hard to get to the mill before it closes during the winter!
