Prusten is a form of communicative behaviour exhibited by some members of the family Felidae. Prusten is also referred to as chuffing or chuffle (verb and noun). It is described as a short, low intensity, non-threatening vocalization. In order to vocalize a chuff, the animal's mouth is closed and air is blown through the nostrils, producing a breathy snort. It is typically accompanied by a head bobbing movement. It is often used between two cats as a greeting, during courting, or by a mother comforting her cubs. The vocalization is produced by tigers, jaguars, snow leopards, clouded leopards and even polar bears. Prusten has significance in both the fields of evolution and conservation.
"The monthly veterinary report of July 31, 2023 assessed that the pulmonary lesion was smaller. Bloodwork and chuff (blowhole exhalation samples) were unremarkable, with a very low white blood cell count in Lolita's chuff samples. In summary, the veterinarians were seeing incremental improvements in her health. Nonetheless, she was still fighting the chronic infection in her lung, and continued to receive daily Faropenem and antifungal medications
Chuff:
--a short, low intensity, non-threatening vocalization made by a snow leopard.
--blowhole exhalation samples (such as from an orca.)
