Unraveling the Mystery of Cat Purring: Scientists Make Groundbreaking Discovery

Scientists have discovered that cats' purring is not caused by active muscle contractions, but rather by squishy pads in their vocal cords. These "purring pads" increase the density of the vocal folds, allowing them to vibrate more slowly and produce the low-pitched purr. The research challenges the belief that larger animals with longer vocal cords are needed to produce low-frequency sounds. The study could provide insights into the role of purring in cats' health and well-being, potentially leading to new technologies for calming devices or treatments for pain and anxiety.
