A 2009 Current Biology study led by University of Sussex researcher Karen McComb found that cats purring to solicit food embed a hidden high-frequency element peaking between 220 and 520 Hz (mean 380 Hz) inside the usual low rumble. The team said the component resembles a human infant’s cry, and 50 volunteers rated these “solicitation…
