These detections had been distinctive as a result of the cats had been each a part of a CDFW inhabitants examine and sporting GPS collars. Much more distinctive is these two mountain lions had been associated (mom/daughter).

Mono County additionally had not had any detection in wild birds but both. CDFW doesn’t anticipate this virus to have a inhabitants degree influence on California mountain lions, bobcats or different carnivorous mammals.
