Guinea pigs are prey animals, so they appear to be skittish and scared when you bring them home for the first time, freeze at the slightest sound, run away, or even resist eating until any movement has stopped, or when you have left the room.

You might be shocked to hear that certain caves are vibrating, and, of course, you might be curious why they’re doing this.

Let’s discuss in depth the reasons why the guinea pigs are vibrating. It would be best if you learned to judge the various sensations by separating a peaceful sound from an unhappy or frightening one.


#1. Wheeking

A distinctive (and expected) vocalization produced by guinea pigs and is most frequently used to express anticipation or enthusiasm, mainly when fed.

It sounds like a long, noisy squeal or whistle, and occasionally wheeking will merely act as a call for attention.

Often guinea pigs can make a loud wheeking noise in expectation of having some delicious snacks as their owners open the refrigerator or get out of the food container. (please read here why do Guinea pig whistle)


#2. Purring

Purrs have different interpretations, depending on the pitch and the corresponding body language.

Guinea pigs who feel happy and comfortable will make a deep purring rhythm, followed by a quiet, peaceful stance.

However, if the purr is higher pitched, particularly at the end of the purr, this is more likely to be an irritating sound.

The guinea pig causing this noise is going to be nervous and may even appear to vibrate.


#3. Rumbling

The guinea pig’s rumble is more profound than the purring noise. It’s made when a man’s romances are made by a woman and sometimes by a woman in the season.

Sometimes followed by a kind of “mating dance,” rumbling is often referred to as “motorboat” or “rumble strutting.”


#4. Teeth are chattering

This is an offensive vocalization, a sign of an irritated or disgruntled guinea pig.

Teeth chatter is also followed by a guinea pig showing teeth that sound like a yawn, which means “back off” or “stay away.”


#5. Hissing

This is an offensive auditory stimulation, a sign of an irritated or disgruntled guinea pig.

Teeth chatter is also followed by a guinea pig showing teeth that sound like a yawn, which means “back off” or “stay away.”


#6. Cooing

Cooing expresses reassurance to the guinea pigs. It’s a sound most commonly, but not entirely, made by a parent of guinea pigs to its children. (please read here how to convince your parent to get Guinea pig)


#7. Shrieking

The fairly unmistakable alarm, fear, or pain of a guinea pig is a loud, rising squeak called a shriek. (Please read here why Guinea pig cry)

It’ll be smart to check your guinea pigs if you notice this noise to make sure everything is okay and that none of them gets hurt.


#8. Whining

A complaining or moaning sort of squeak may express frustration or displeasure with something you or another guinea pig are doing.


#9. Chirping

This sounds like a bird chirping and is maybe the least known (or heard) of the sounds that guinea pigs produce.

The chirping guinea pig can also appear to be in a trance-like mood. The sense of this “song” is the topic of much controversy, with no definite answers.



Why do guinea pigs vibrate? Only try to note that your guinea pig is a live thing, and it’s just like a human that can go through changing moods.

And though it can be possible to ignore the mental condition of your guinea pig.
