As I mentioned in a different post, I have only been feeding ferrets a raw diet for a little over a year, and so I can not comment on the long term effects this type of diet will have on my ferrets' health or length of life. What I can comment on is how kibble has affected my ferrets. I have had ferrets (in the plural - at one time as many as 36) in my home continuously since 1985. That is over 20 years. During that time, my hobs/gibs averaged a lifespan of 7 to 8 years old, and my jills/sprites averaged a lifespan of 8 to 9 years old. This includes my ferrets who had ADV. Yes, I have had some ferrets die younger, but 8 years is the overall average lifespan for my ferrets who ate a kibble diet. Currently, I have one 8 year old ferret, Monty, who is still doing very well. She does not and has not had either adrenal disease of insulinoma. She is still quite active, and has a beautiful plush coat. She is 1 of my 2 ferrets that eats only kibble. And, while I have had cases of both adrenal disease and insulinoma, that has not been a major concern for me with my ferrets. For me, most of my ferrets have passed away because of ADV, heart problems, or unusual cancers. Many of my ferrets died having both adrenals in place and no signs of insulinoma. Now, maybe the ferrets I now have that eat a raw food diet will live longer and even healthier lives. Only time will tell. But, the point I am trying to make here is that while I am sure that diet plays a role in the over all health of a ferret, I do not believe that kibble is the main reason many ferrets live short lives or have many health problems. I think it is likely that a number of factors play into this, including diet, genetics, other husbandry issues, and the age at which the ferrets are spayed and neutered. I do think it is good that people are questioning things like diet, and are exploring alternative feeding techniques. There is a lot that we have learned about ferrets and their needs over the last 25 years, but there is still a lot more we need to learn. None of us are experts, really. But, by discussing issues about the health and welfare of ferrets, we can all learn from each other. Danee DeVore ADV - If your ferret hasn't been tested, you don't know!
