Warning - graphic footage of snow leopard eating prey. How often do snow leopards take down a large prey like an ibex? On average, about every 8-10 days, though we have observed at least one instance of a female hunting more frequently when they have cubs. A snow leopard will take 3-4 days to consume a large prey animal and will defend the site from scavengers like vultures.
