Snow leopards patrol Asia's high cliffs with fewer than ten thousand adults
Panthera uncia wears whitish-grey fur with black spots and large flank rosettes across Himalayan and Central Asian mountains from roughly 3,000 to 4,500 meters. Once parked in its own genus Uncia, it now sits in Panthera as a Vulnerable cat with under 10,000 mature individuals.
Everything about this cat is tuned for cold rock. Small rounded ears lose little heat, broad fur-soled paws spread its weight on snow and grip loose slopes, and a tail 80 to 105 centimetres long, thick with stored fat, helps it balance and doubles as a blanket over its face during sleep. Hairs up to 12 centimetres long cover a stocky body that stands only about 56 centimetres at the shoulder; males weigh 45 to 55 kilograms and females 35 to 40. Large nasal openings warm the dry air it breathes, yet it has no special adaptation to thin air.
It cannot roar. Although its hyoid bone is only partly ossified, like those of roaring cats, its vocal folds are just 9 millimetres long and offer too little resistance to air. Its shorter muzzle, domed forehead and slender 28.6-millimetre canines also set it apart from the rest of Panthera.
Genetically its closest relative is the tiger, from which it probably split between 3.7 and 2.7 million years ago, and the genus itself likely arose in northern Central Asia. Schreber named it Felis uncia in 1777 from Buffon's account, placing it wrongly on the Barbary Coast among other places; the name uncia and English ounce trace through Old French back to the Greek word for lynx. The oldest definite fossil of the modern species comes from Niuyan Cave in China in the Late Pleistocene, and fossils named in 2022 and 2025 from France and Portugal hint that relatives once lived in Europe.
Solitary and active at dawn and dusk, it hunts wild ungulates and livestock across cliffs at 3,000 to 4,500 metres from the Hindu Kush to Mongolia. Fewer than 10,000 adults survive, and poaching and habitat loss threaten them.
