Fraser Fur Farm, believed to be the largest wildcat farm in the U.S., has been confirmed open as of March 2014. This confirmation comes after an anonymous visit by activists, who confirm the farm remains in business.
Fur farms close (and occasionally, open) frequently, and status updates can be so hard to come by, that Coalition Against Fur Farms exists in part to provide these status updates as they come in.
Fraser Fur Farm is best documented in this anonymous report, and the book Operation Bite Back by Dean Kuipers.
The farm is believed to imprison coyotes, fox, and bobcats, according to records obtained by CAFF.
