The first 5 ingredients in the Natural Formula are
2)Ground Brown Rice
3)Ground Yellow Corn
5)Dried Beet Pulp
I was a little concerned with the fact that Corn is in there, however after reading on their website about their ingredients, and why they use them, I am no longer concerned. As well, after reading their testimonials I was impressed! If you are looking for a formula without Corn, their Holistics line would be a good choice, I think. I was planning on going with the holistic Chicken, but it is not available in my town (unfortunately covenience must win sometimes!!) Apparently the Natural formula was the next closest to the holistic. Anyway, if you want more info, the website is eaglepack.com.
