This exciting video was taken in August 2010 at the Tost Mountain study area in South Gobi, Mongolia where Panthera and the Snow Leopard Trust are collaborating on the first ever long-term study of snow leopards. We believe that the first cat to walk out of the frame is the mother of the other two cats photographed. The cubs are approximately two years old in these photos. In April 2011, we placed a radio collar on the second cub, a female we named "Anu". This film clip is actually 61 images taken about a half second apart by one of our remote automated cameras.
