Many people say that when the comets are comfortable and happy, they will make a squeaky sound, which is caused by the breathing that occurs in the diaphragm and throat.
It turns out that the idea of being happy can be misunderstood, in fact to ask us to touch them, or to continue to provide a comfortable environment for them to sleep.
Now, when a cat is injured or frightened, the cat will also squeak, which researchers believe is related to the ability to treat snoring.
The bark frequency of most domestic cats is 26 Hz, the same frequency that has been found to promote bone and other body tissue healing.
This is why cats often roll up a wounded cat (or other small animal) and they are snoring and they are helping.
