Answer:
First, please understand that Epigen is not a "grain-free" food in the sense that others in the market are. We have addressed the fundamental problem of starch, not just from grains. Others have not.

See:

For your first question, please see this link: http://www.wysong.net/pet-health-and-nutrition/pet-foods-for-both-canine-and-feline.php.

As for pricing, Wysong manufactures its own foods and does not pay an outside toll manufacturer. Also, marketing costs--which make up the majority of many brand's pricing--are kept down. Thus, ours are the highest quality foods in the market but at a reasonable price.
