What's going on with the sound of the cat? In fact, the cat's whistling voice may indicate that it is sending a signal to pay attention, communicate or protest. It is also possible to "sing" to you and express its excitement. If it is particularly fierce, accompanied by rolling and flicking, it may mean it is being frightened or feeling very nervous.

The sound of cats is usually made in an environment of comfort and trust, because they are very relaxed and in a good mood. Usually, the cat will make such a sound when the owner touches the cat's head and chin. This sound is the sound made by the muscles in the throat when breathing.

Another situation is that the cat is very angry and makes a whirring sound at this time to deter the opponent from an offensive or defensive posture. The owner should take the cat away from the strange dog or other cats immediately, or stop what the cat doesn't like, otherwise the cat is likely to attack.
