The meaning of the guinea pig's cry:

1. If the guinea pig makes a gurgling sound. It means that it is in a good mood, especially when it sees its owner coming home, it will make this sound while approaching the owner.

2. If the guinea pig makes a grunting sound. That means it is hungry. After the owner hears this sound, he should hurry up and prepare food for him.

3. If the guinea pig makes a shrill scream. It means that it is frightened, particularly panicked, and is in danger or pain, and the owner should calm it down immediately.

4. If the guinea pig makes a clucking sound mixed with a high-pitched hum. It means that the guinea pig is in a good mood, just like humans humming a song to express their joy, usually after eating.

5. If the guinea pig makes a sound similar to grinding its teeth, it means that the guinea pig is very angry at this time. Do not tease it, as it is likely to be attacked by it.
