Here are some of the most common guinea pig sounds:
* Wheeking: This is the most common sound, a high-pitched squeak, usually used for getting attention or expressing excitement.
* Purring: A rumbling sound similar to cats, usually indicating contentment.
* Chirping: A short, high-pitched chirp, often used for communicating with other guinea pigs.
* Squealing: A loud, shrill sound, usually indicating distress or fear.
* Whistling: A high-pitched whistle, sometimes used as a warning.
* Clicking: A clicking sound made with their teeth, often used to grind them down.
Croaking is more common in amphibians, while chirping is more typical of birds. If you hear a guinea pig making strange, unusual sounds, it's best to consult a veterinarian to rule out any health issues.
