What you have to realize is that the ferrets in America come from a relatively small gene pool. There's a *LOT* if inbreeding. Although the major breeders have been trying to remedy this in the last few years, for many years they had closed communities. Although this reduces the risk of bringing diseases into the breeding colony, it doesn't take a mathematical genius to realize that pretty soon everyone is related to everyone else. Even in the show communities there's only so many breeding animals, since breeding isn't the easiest thing in the world only the most devoted breed. The breeders tend to breed with other ferrets in the general region, since they "network" at the shows, and you just don't have time and funds to travel all the way across the country to shows. So there's a lot of inbreeding that way (even though it's much more closely watched, but still if you go back 10 generations or so...). Although all the good breeders I know keep track of this and never intentionally inbreed, there was a long time when it wan't done, and we can't undo what is already done. This is starting to become more of an issue in the show communities as well. As a matter of fact, someone just imported two boy ferrets from Europe. She's renting them out to breeders for around $75 per, er, "performance". There's already a waiting list for these boys, since we've been becoming acutely aware of the inbreeding problem, since in the last few years people have been studying cancer and tumors in ferrets, and the statistics are rather alarming. So needless to say, they are going to be two very happy (and tired) little boys come spring. ;-) I would like to see the statistics for the Western U.S. versus the Eastern U.S. as well. I understand that there's a lot of polecat in the ferrets out there, since they interbred them for their fur, and unethical furriers would sell them to make a quick buck. (Very often fitch were sold as ferrets, they look the same, but fitch bear wild personalities and don't make good pets. Hence a lot of "ferret attacks" can be attributed to the fact that it wasn't *really* a ferret!) I'm curious to find out if that had any impact on the bloodlines out there, and if it effected the cancer/tumor rate. (Obviously it would not effect the ferret farm ferrets that were shipped out there, so that would be a difficult statistic to get.) Urban, How about telling us how ferrets are kept in Sweden? I understand that ferrets are usually kept as indoor/outdoor pets there, is that true? If so, aren't there a lot of ferrets that just "dissapear"? Are indoor ferrets generally caged or allowed to be house pets? Are you involved in one of the clubs? If so, what's that like? I'm sure that I'm not the only one interested, which is why I'm asking this on the list. You can probably tell everything about the U.S.A and Canada just from conversations on the list and Usenet, but if you have any questions I'm sure we could all help out. - Nancy Nancy Hartman CIS graduate student [log in to unmask] U. of Delaware President and founder, Delaware Valley Ferret Club Owner of Percy & Bree [Posted in FML issue 0377]
