I've been told that my note about the ferret who ate that 8 in 1 food could be misinterpreted so here is a clarification: I am trying to find out if there has been a definite case of the cyanuric acid and melamine crystals in ferrets because 1. to date it has not been documented in ferrets, and dogs from which ferrets are descended are less prone to the problem than cats. 2. So, it is an unknown how easily the crystals can form in ferret urine. (All types of urine differ in a number of factors including typical pH.) 3. Also, if those crystals do form in ferrets then because ferrets have more narrow "tubing" than cats and dogs is there an increased risk of not only kidney damage but also of blockage lower in the urinary track such as in the urethra? 4. And finally, since that one type of food was recalled because it was produced at the same as the contaminated foods I wanted to find out if there was actual documented cross-contamination rather than just the possibility of such cross- contamination. (So far there is one food from a different location which did have actual cross- contamination, so if there was actual cross-contamination it probably even more makes sense for any manufacturer to recall all types of foods made at that time (as happened with that one type of 8 in 1) rather than just ones with those known ingredients.) So, I asked about the crystals, and also in my FML post (perhaps also in my FHL post but i can't recall off-hand) I gave the info on which specific 8 in 1 food was involved because there are sure to be those who missed the original announcements who will want and perhaps even need to know (i.e. may have one of the recalled bags). Here is the FDA announcement again for those it can help: http://www.fda.gov/oc/po/firmrecalls/chenango05_07.html Chenango Valley Pet Foods is now expanding the recall action to include those pet foods that do not contain rice protein concentrate but were manufactured during periods when rice protein concentrate formulas were processed. The recall of these products is precautionary due to the possibility of cross-contamination. ... 8 in 1 Ferret ULTRA-BLEND ADVANCED NUTRITION DIET, NET WT. 20 LBS, UPC 26851 00413, Code: C7072 All that had been said was that the food was the cause but there was not more data, and in both cat and dog health care there have been both cases which were clearly the food as the cause but non- acceptance of that by some food makers, but other cases with the opposite where other causes turned out to be to blame. All that anyone can do when little info is given is to ask questions. With no other ferret reports that I have been able to find the data in this situation become especially important to help others. I am sorry that I was so brief but my own life has had some huge demands recently with my elderly father (almost 93) extremely ill. Yes, I am very sorry that KIller passed on, but was thinking that perhaps information could save others. If I'd been under less time pressure I'd have done a better job of getting that across. I apologize for not being clear and hope that testing results are shared because this poor little boy's appears case seems to be the only case (so far?) in which people can possibly learn about cyanuric acid-melamine crystals in ferrets, so the test results become especially important and hopefully there will be a detailed report should the testing not show an alternative kidney disease cause. (This particular food maker appears to be more consciencous than some others but I also kind of hope that some urine and kidney tissue is looked at independently with a report.) The research info on those crystals specifically can be linked to from past posts. Hopefully, that is more clear now.
