The Snow Leopard! Slightly misleading name, as they’re more closely related to tigers than leopards but never mind that, they’re also known as “mountain ghosts” which is cooler than either. They’re such solitary animals that there is no collective noun to describe a group of them. We should come up with one. Suggestions via the contact page please. Also, they don’t roar, but chuff. Going to leave you to work out what that might sound like.
