I second the Amen to Wolfy!!! I buy mostly all of my bedding from an ADV + person. I have for years. The sale of these items are what helps pay for the medical care of the ferrets. My ferrets sleep on this bedding every day. I test my ferrets every six months and they are neg. I have the papers to prove it. There are other things that can be spread by bedding, not just ADV. A little soap, water and bleach and a lot of common sense go a long way. I wash EVERYTHING I get at a ferret show, no matter who I buy it from before my ferrets are allowed to touch it. If it disintegrates in the washer then I consider that a good thing. Better I know now than be having surgery to remove it from my ferret later! [Posted in FML issue 4708]
