I thought lynx cat was more a grade. Only bobcats with select fur, white bellies, are in the "lynx cat" pile. The rest are bobcats.
That’s the way is started out back in the late 70s and early 80s. Lynxcats were the nice pale heavy western bobcats. The eastern and southern bobcats were still bobcats.
At some point, not sure what year, it got too confusing to have Lynx, lynxcats and bobcats. So all bobcats became lynxcats. Which cleared up part of the confusion. Some confusion remains today between Lynx and lynxcats.
Additionally, when doing CITES paperwork to get the pelts across the border and back again, USFW needed some sort of standardization - all bobcats or all lynxcats. Not both.
