Hi everyone, I'm new here, and not a chemist. However, I wonder if some experts can offer an explanation as to why a very high gamma dose (>60kGY) would cause "demyelination" (a disease of the nervous system) in cats that ate the food. The company is testing both the food and the packaging, but, so far, nothing specific that would cause "demyelination". Although, it's not clear that they are performing the proper tests. From what I've found, so far, possible causes of demyelination (in humans) are: malnutrition toxins viruses radiation We need to know what specific substances to test for in the packaging, and the food, and how the affected kitties can be treated. Many have already been put to sleep. Please follow these links for the newspaper article, and info posted on the company's website: Sidney Morning Herald: http://www.smh.com.au/cgi-bin/common/popupPrintArticle.pl?path=/articles/2008/11/27/1227491735559.html [Broken] Champion Pet Foods: http://www.championpetfoods.com/orijen/Australia_Consumer_Release_Nov28.pdf [Broken] This is a real life problem that needs a scientific explanation. Please share this information with others. Thanks very much.
