Positive Sounds:
* Purring: A low rumble or vibration, similar to a cat's purr, is a very good sign. It indicates contentment and enjoyment of your attention.
* Chirping: A high-pitched, bird-like chirp often means your guinea pig is excited or happy. This can be a response to being petted, receiving a treat, or just being in a good mood.
* Wheeking: A short, sharp "wheek" can be a way of saying "hello" or asking for something, like food or a scratch.
* "Rumblestrutting": A combination of low rumbling noises and a swaying, strutting gait. It's a sign of happiness and excitement, especially when they're showing off for you.
Neutral Sounds:
* Teeth Grinding: This is a normal sound, but it can also be a sign of discomfort or pain. It's important to observe other behaviors to see if your guinea pig is stressed.
* Clicking: A clicking noise can be a sign of a healthy guinea pig eating.
Negative Sounds:
* High-pitched Squeaking: This can indicate fear, pain, or distress. It's important to assess the situation and ensure your guinea pig isn't in danger.
* Loud Squeaking: This is usually a sign of aggression or territorial behavior.
* Whistling: A high-pitched, shrill whistle can indicate pain or discomfort.
Other Factors:
* Individual Personality: Some guinea pigs are simply more vocal than others.
* Handling and Interaction: A guinea pig who is used to being petted and handled will likely make more positive noises.
* Environment: A comfortable and safe environment can encourage vocalization.
Remember: Observing your guinea pig's body language and overall behavior is crucial. If you notice any concerning sounds or behavior, consult a veterinarian.
