Teasing? Or is he angry? No, it’s Fleming’s reaction! Our beloved spotted cats, however, and striped ones too, have a special organ in the palate. Are you ready? Vomeronasal! Or the Jacobson organ. If you had such an organ, you would also open your mouth like that before dinner, trying to figure out what was being cooked there — cutlets or pies.
This is not a reflex, the snow leopard opens its mouth intentionally. This is how the snow leopard captures odors better with its special organ in the nasal cavity. Scientists describe this sensation as "a combination of taste and smell." Even goats and horses do this. Therefore, the snow leopard here is not at all angry or cheerful. He’s smelling and tasting at the same time.
