Domestic cats may dominate the living room, but one important difference (other than size) sets them apart from the jungle king. It’s vocalization. Most large cats, such as lions and tigers, can roar loudly to announce their existence and protect their territories, but domestic cats are stuck in less ferocious meows and rumblings.
So why can’t I have a cat? Goodness knows it helps them roam the house (even more so than they have already done).
It is related to the physiology of the cat’s larynx and throat, which helps to produce vocalizations in these cats. John Weibull, a mammal curator at the Carnegie Museum of Natural History in Pittsburgh, said these sounds are mutually exclusive in cats because of the way they throat and roar.

Throat is a unique sound because it occurs both when the cat inhales and when it exhales. Vocalization seems to have evolved first in cats and is widespread in felines, Wibble said. Throat cats include domestic cats. Bobcat, Ocelot, Lynx, cougar, Cheetah..
“Roars are much rarer among cats and have evolved in certain strains of big cats,” Weibull told Live Science in an email.These cats Panthera Genus including Lions, Tigers, Jaguar When Leopard.. One exception here is the snow leopard. This may have lost the ability to roar. Anatomy Journal..
Like humans, the sounds that cats make can be heard through a box of voice called the larynx. The difference between a cat roaring and a roaring cat begins here, but it’s unclear exactly how cats make these sounds, Wible said.
The roar comes from the winding bones of the throat
The mammal’s larynx is in the throat, and the air passing through its structure makes a sound. The hyoid bone and vocal cords are two important parts of the larynx that produce the cat’s vocalizations.
“All mammals have bones near the mandible, which is the hyoid device, in the neck, and these bones connect directly to the base of the skull, either directly or through ligaments,” Wible said. One of the major differences between roaring and throating species is in the hyoid bone.
“The roarer has a unique arrangement for one pair of bones in the hyoid bone device called the hyoid bone,” Wible said. “Epihyoids, not bones, are elongated elastic ligaments.” Flexible cartilage allows animals to lower the larynx and make deeper sounds.
The rumbling comes from a variation of the larynx
Another important difference between roaring and throating cats lies in the larynx itself, which is essential for throating, Wible said. “The throat ringing is caused by a very rapid spasm of the vocal cord muscles in the vocal cords of the larynx.”
Roaring cats have longer, heavier, more elastic, thicker, and thicker layers of tissue that make up the vocal cords.According to a study published in the journal, the organization is strong and flexible, allowing these big cats to make a low-pitched, roaring roar. PLOS One In 2011, but it doesn’t mess with them.
Whatever physiological development led to the cat’s throat, “it must have provided some evolutionary benefits to be maintained in the cat’s lineage,” Weibull said. Scientists are not sure exactly what their role in the wild is.The theory is that throating Healing and calm Mechanism or what it may help to hide Kitten barks from predators..
“The cat in my house, as far as I know, snorts as a sign of satisfaction,” Wibble said. “But I don’t know if it’s the same with the throating wild cat breed.”
