Snow Leopards are carnivores and actively hunt their prey, though, like all cats, they are opportunistic feeders, eating whatever meat they can find, including carrion and domestic livestock. They can kill animals three times their size, such as the Bharal, Himalayan Tahr and Markhor but will readily take much smaller prey such as hares and birds. Unusually among cats, snow leopards also eat a significant amount of vegetation, including grass and twigs.
