This isn't really nit-picking, because it is an important distinction, but the corn Iams uses is NOT gluten, but meal and grits. Corn gluten is relatively high in protein, and in some pet foods is used to inflate the protein levels. Ferrets cannot get the benefit of this protein, so corn gluten is definitely a bad ingredient for ferret foods. Also, I got another email from Dr. Jerry Murray, who said that according to his information, the corn in Iams does not contribute to the protein levels, and that they add dl-methionine, a urine acidifier, which is also a good thing. And Todd, you did spell "sorghum" correctly! I've been reading up a bit on grain sorghum (there are other types of sorghum, including "broomcorn" which is used to make brooms). The sorghum plant looks a lot like corn, but is not really related. It is used primarily in this country for livestock feed, but is an important human food crop in Africa and Asia. A couple good reference web sites are http://www.ksgrains.com/sorghum/educate.html and http://encarta.msn.com/find/Concise.asp?ti=003C5000 Todd is right, we all still have a lot to learn about ferret nutrition, and at this point, we can only go with what seems to work for us and those we trust.
