In 2004, while climbing in Ladakh, India, I had an encounter with two snow leopards hunting a dzo (part cow-part yak). Amazingly the dzo was young, healthy and at least 7 times, the snow leopards body weight. Until this footage, there was only anecdotal evidence that snow leopards would attack something so large and healthy. I was extremely lucky to capture footage of the attack.
Recently, I made a short documentary about my encounter. I should have done this 4 years ago, when it was the first hunting footage ever taken of snow leopards in the wild, but I inexplicably sat on it for 4 years. Oh well, better late than never. The link can be found below:
