Do lions purr?
The purring sound of animals from the cat family is produced by a vibration of the vocal cords coming and going apart. The sound is audible and exhaled, and it changes in tone between the different sexes in the family and even in the same animal.
Purring is mainly associated with the family of cats but also raccoons purr and bears as well as foxes, rabbits and gorillas gargle when eating, just like me!
Kittens begin to purr almost from the moment of birth, veterinarians maintain that purring is their way to contact their mother and siblings. The puppies are helpless, blind and deaf, but they recognize the purr, and so they find their mother and tell her where they are. But this is just one meaning to the cat's purring. Most people interpret it as an expression of satisfaction, while other studies show that cats also purr when they try to soothe themselves. Many other studies have found that purring, in its low frequency fluctuations, is a "natural healing mechanism".
Larger members of the cat family can purr only if they can not roar. Which means that the lion can not gargle. His satisfaction is shown with the help of a blink. Closing eyes is a sign of a sense of security, because when his eyes are closed he is exposed to the threats of other predators. The domestic cat also shows signs of affection by slow blink of the eyes...
But he can not roar.
