Decoding the Enigmatic Purring of Cats: New Insights Unveiled

Austrian scientists have discovered that connective tissues embedded in cats' vocal cords play a crucial role in their ability to purr, challenging the prevailing hypothesis about how cats produce these low-frequency rumblings. The researchers excised the larynxes of eight deceased domestic cats and found that purring sounds could be produced without muscle contractions, suggesting that cats rely on the same mechanisms as other mammals for vocalizations. The study also highlights that the reasons why cats purr remain a subject of debate, with theories ranging from relaxation and pain relief to manipulation for food.
