It looks like a dreaded food debate regarding by-products and let me mention another product in pet foods called "animal digest". I got my information on research done by Michael W.

The latter was published in 2001. Suka Malone Business Enterprises The Field Museum 1400 S. Lake Shore Drive Chicago, Illinois 60605 t: 312/665.7651 f: 312/665.7677 [Posted in FML issue 3722]
