Click the title link for a very informative collection of articles about companion pets and nutrition. This would make a great resource for anyone interested in learning more about species-appropriate food options for their 4-legged family members.
Included subjects range from Dr. Pottenger's Cat studies in the 30's - 50's, to the current AAFCO's guidelines for pet food labelling, and include anecdotal information about the benefits of a raw diet, as well as a discussion of the risks. Since it is a public forum, there are also general comments from other readers, but the articles do have supporting links and footnotes. Hope this is helpful!
