Snow leopards are carnivores that primarily hunt wild mountain ungulates, especially blue sheep, Siberian ibex, argali, and Himalayan tahr. A single snow leopard needs about 1.5 kg (roughly 3.3 pounds) of meat per day, which translates to roughly 20 to 30 adult blue sheep per year.
Primary Prey Species
Five prey animals make up the core of the snow leopard’s diet across its range in Central and South Asia: Siberian ibex, blue sheep (also called bharal), argali wild sheep, Himalayan tahr, and marmots. Together, the four large ungulates plus domestic cattle and yak account for over 52% of the total biomass snow leopards consume globally. Which species dominates depends entirely on where the snow leopard lives. In the Himalayas, blue sheep and Himalayan tahr are the staples. Across the mountains of Central Asia, Siberian ibex and argali take that role.
What’s striking is the size difference between predator and prey. Snow leopards typically weigh 25 to 55 kg (55 to 120 pounds), yet they regularly take down ibex weighing around 76 kg and argali reaching 80 kg. That means they routinely kill animals that outweigh them by a significant margin, ambushing prey on steep, rocky terrain where their powerful hind legs and long tail give them an advantage.
Small Prey and Seasonal Shifts
Large ungulates form the backbone of the diet, but snow leopards are opportunistic. Marmots are a particularly important secondary food source during warmer months when these large rodents are active above ground. Snow leopards also eat pikas, hares, and ground-nesting birds when the opportunity arises. In summer, when marmots are plentiful and easier to catch, snow leopards may rely on them more heavily, especially younger or smaller cats that aren’t yet skilled enough to consistently bring down large prey.
How Often They Kill
A snow leopard kills a large ungulate roughly every 10 to 15 days. After making a kill, it typically stays with the carcass for up to a week, feeding repeatedly rather than abandoning the remains. This pattern of infrequent large kills followed by extended feeding bouts is well suited to their harsh, high-altitude environment where prey is scattered and energy conservation matters. A study tracking snow leopards in Mongolia found a slightly higher rate of one ungulate kill every 8 days, though that population had access to both wild prey and livestock.
Livestock in the Diet
Snow leopards do kill domestic animals, and this is one of the biggest sources of conflict with herding communities across their range. In Mongolia, researchers found that livestock made up about 27% of snow leopard kills, with wild prey accounting for the remaining 73%. That ratio is notable because livestock in the study area outnumbered wild ungulates by at least ten to one. Snow leopards still strongly preferred wild prey even when domestic sheep, goats, and yaks were far more abundant. Cattle and yak collectively contribute about 9.6% of the total biomass in the global snow leopard diet, making them a meaningful but secondary food source.
The conflict this creates is real. For a herding family, losing even a few animals to a snow leopard can represent a significant economic blow. Conservation programs in several countries now use livestock insurance schemes and predator-proof corrals to reduce these losses while protecting snow leopard populations.
Why Snow Leopards Eat Plants
Despite being strict carnivores, snow leopards regularly eat grass and other plant material. Researchers have documented this behavior both in the wild and in captivity, and it turns out no one is entirely sure why they do it. Three leading explanations exist. One suggests the plants provide some minor nutritional value. Another proposes self-medication, where plant fibers may help expel intestinal parasites. The third, and most widely discussed, is that eating grass helps snow leopards pass hairballs, preventing fur from accumulating in their digestive tract. Given how thick their coat is (essential insulation at elevations above 3,000 meters), hairball management would make practical sense. Still, no study has definitively confirmed any single explanation.
Diet Varies by Region
One of the most important things to understand about snow leopard diets is that they’re not uniform. A snow leopard in Nepal eats differently from one in Mongolia or Kyrgyzstan. In Nepal’s Himalayas, blue sheep dominate the diet. In parts of Central Asia where blue sheep don’t occur, Siberian ibex become the primary target. In areas where wild prey has been depleted by hunting or competition with livestock, snow leopards shift more heavily toward domestic animals or smaller prey like marmots.
This regional flexibility is both a survival advantage and a conservation concern. Snow leopards can adapt their diet to what’s available, but when wild ungulate populations decline, the cats increasingly turn to livestock, which escalates human-wildlife conflict and puts snow leopards at greater risk of retaliatory killing. Maintaining healthy populations of wild mountain ungulates is, in a very direct sense, one of the most effective ways to protect snow leopards.
