Why Is Your Cat So Disgusted With You?

The video explains the misunderstood facial expression of cats, often perceived as disgust, which is actually the Flehmen response. This response, used by animals like cats, horses, and giraffes, involves the vomeronasal organ to enhance their sense of smell. The organ, located in the mouth, requires scents to be dissolved in fluid to be detected. The Flehmen response is primarily for detecting scent signals from the same species. Humans, however, have lost the ability to use this response due to evolutionary changes.
