Prusten is a sound made by the tiger and the snow leopard, also known as chuffing or chuffle (verb and noun). It is a low-frequency equivalent to the purring found in domesticated cats. The animal's mouth is closed and it blows through the nostrils, producing a breathy snort. This sound is non-threatening and often used when two big cats encounter each other on neutral territory, or between courting pairs. Mothers use it to their cubs as a form of reassurance. It has been known for tigers and snow leopards held in captivity to use this sound to keepers. Prusten is a German word. It means to sneeze or snort.
