Michael and Greg Yes I've heard of this problem, and talked to a couple of vets earlier this summer who were investigating it. There have been a several reported cases over the last year and a half or so, all in kits or young ferrets at stores or distributors. So far treatment with vitamin K seems to cure the problem, and the last I heard, there were no further problems in these ferrets. There are no signs of contagion and they have not yet found an environmental or other agent that may be causing it. I forwarded your email address to the vets I know involved. If you don't hear from them in a few days, let me know. Linda Iroff International Ferret Congress http://www.ferretcongress.org [Posted in FML 5721]
