Understanding Cat Vocalizations

The video explores why domestic cats can't roar but can purr, unlike lions, tigers, leopards, and jaguars, which can roar but not purr. It discusses the role of the hyoid bone and vocal folds in these abilities, highlighting the snow leopard as an exception. The video concludes with a thank you to viewers.
