how do cats purrrrrrr?

Answer 1

asi:
prrrrrrrrrrrrrrrrrrrrrrrr

Answer 2

I don't think anyone knows for sure but I did find this: It was once thought that the purr was produced from blood surging through the inferior vena cava, but as research continues it seems that the intrinsic (internal) laryngeal muscles are the likely source for the purr. Moreover, there is an absence of purring in a cat with laryngeal paralysis. The laryngeal muscles are responsible for the opening and closing of the glottis (space between the vocal chords), which results in a separation of the vocal chords, and thus the purr sound. Studies have shown, that the movement of the laryngeal muscles is signaled from a unique “neural oscillator” (Frazer-Sisson, Rice, and Peters, 1991 & Remmers and Gautier, 1972) in the cat’s brain.

Answer 3

Cats produce the purring noise by vibrating their larynx, or voice box, in a particular manner. A timing mechanism in the brain sends neural messages to a muscle in the larynx, rhythmically opening and closing the air passage approximately 25 times per second [1] and has strong harmonics. Combined with the steady inhalation and exhalation of air as the cat breathes, a purring noise is produced.[2]

All cats are able to purr. However, the entire panthera genus is able to purr only while exhaling. Cats that roar lack the purring vocal chords, and use the vocal chords in charge of roaring and growling instead, making a noise similar to growling when they purr. As a result, the two sounds are often confused. The roar in these cats is a very loud growl with respect to the production method. Additionally, because these chords can only be used while exhaling, the purring equivalent sound can only be made while exhaling. Cats not members of the panthera genus, even larger ones such as the cheetah, purr.

Why and how do cats purr?
Why and how do cats purr?

Purring is part of every cat's repertoire of social communication, apparently created by the movement of air in spasms through contractions of the diaphragm. Interestingly, purring is sometimes heard in cats who are severely ill or anxious, perhaps as a self-comforting vocalization. But, more typically, it is a sign of contentment, first heard in kittens as they suckle milk from their mother.

In adults, purring is heard in domesticated cats when they are petted, and in feral cats during sexual or other social contexts. Like submissive posturing among dogs, purring may be a signal of appeasement to other cats or to people, a way to communicate that the purring cat need not be threatened.

As with many behaviors in dogs and cats, the original presumed purpose of the behavior may not be directly relevant in a pet home. But we do believe that, when our healthy pet cats purr, they are happy and at peace.

Answer 6

They vibrate their breath through their throat, similar to us sighing. Their purr is actually healling for them as well, i.e. the gentle vibration heals them. So always make sure your cat gets plenty of purrs!!

Answer 7

When it feels content, it scratches its vocal cords to create a purring sound. I read that from a childrens' book about animals a LONG time ago.

Answer 8

I think they have cords in the throats, just like our vocal cords, that they can vibrate and make that prrrring sound.
