As felines, cats can convey different emotions and messages through different throat sounds. In addition to the common vocalizations and breathing sounds, what you may not know is that a cat's throat can actually make two different sounds: breathy sounds and guttural sounds.

Breath sounds refer to the sounds produced by cats when breathing, which are usually very slight breathing sounds or hissing sounds. Guttural sounds refer to the purring or purring sounds made by cats. These sounds are usually made when cats feel relaxed or comfortable. ​​​​​​

So, why can a cat’s throat make two different sounds? This is related to the cat’s throat structure. The inside of a cat's larynx contains special cartilage called arytenoid cartilage, which blocks airflow and creates an effect similar to a resonance box, allowing guttural sounds to be produced. In addition, the cat’s larynx also contains an organ called the parapharyngeal sac, which helps the cat make special sounds when breathing.

Gutteral sounds are usually made by cats when they feel relaxed or comfortable, such as when they are caressed by their owners or enjoy a warm and comfortable environment. This sound is often considered one of cats' ways of expressing that they feel relaxed and content. Guttural sounds can also be regarded as one of the ways of communication between cats, used to express friendship and goodwill between cats.

In addition to guttural sounds, cats can also make many other sounds, such as squeals, hisses, purrs, etc. These sounds are usually cats expressing different emotions and needs, such as when they are scared, in pain, hungry, seeking attention, etc.

In short, cats’ throats can produce two different sounds, which are related to their larynx structure. Understanding these sounds and their meanings can help us better understand and communicate with our cats. If you have a pet cat, develop a closer relationship with them by observing and listening to them. Additionally, if you want to make your cat feel relaxed and comfortable, try gently rubbing their throat with your fingers, which can often elicit pleasant guttural sounds.

In addition to the two different sounds that a cat’s throat can make, there are also many interesting trivia waiting for us to discover. Maintaining curiosity and a spirit of exploration in life, and continuous learning and exploration can bring us more fun and enlightenment.
