Why Do Guinea Pigs Vibrate? 9 Signs They’re Happy!

If you own a guinea pig pet, one action that may come as a surprise is vibrating. Why do guinea pigs vibrate? Why are the guinea pigs doing this, and what does it mean? Is it positive, or is it anything to be worried about? Luckily, vibrating means a positive thing in the cavy world, the simple pleasures of purring.

Guinea pigs also express their joyful moods by sending off comfortable and deep vibrating noises. Vibrating may also signify sensations other than giddiness.

Why do guinea pigs vibrate

Guinea pigs vibrate as a means to interact. Guinea pigs shake for both positive and negative factors and are mostly context-dependent.

It is also critical that you control your guinea pig’s condition, current mood, and well-being. It will help you appreciate what’s going on, how to come to terms with the situation, and whether you need to react in some specific way.

Why Do Guinea Pigs Vibrate?

As a guinea pig owner, vibrating is an unusual and rare behavior that you want to truly understand. Let’s take a closer look at how to react if there’s anything you notice in your pet cavy.

Notice when you’re carrying your guinea pig, and you find that his body is shaking. It usually means your guinea pig is very happy and relaxed. A guinea pig who is at peace and joyful will express his feelings by vibrating his body.

That is why guinea pigs shake. There are a lot of factors to understand why they do such behavior.

In addition to trembling, he also vocalizes his contentment with a few squeaks or purrs.

Guinea Pigs Vibrating: Their Behavior Explained

Every guinea pig is unique, but if you are an expert and used to pet cavies, you can tell that sounds and behaviors can communicate and express different body language and feelings.

So, feelings and emotions are one the factors why guinea pigs vibrate.

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.

It is another thing once they are happy.

Still, in other ways, older guinea pigs show happiness; examples are appreciative, chirping, screeching, being interactive with fellow cavies, and owners.

Like my cavy, Ginger, a Peruvian guinea pig, he makes this vibrating sound when I pet him.

Every time I go home from work, he keeps on jumping like he is asking for attention. I enjoy petting him.

But when he is angry, I make sure that he will calm down and be cheerful again.

Behaviors And Actions Showing A Happy Guinea Pig

Are you wondering why your pet shows the following behaviors?

  • Keep engaged from time to time
  • Popcorning
  • Rubbing his nose into his guinea pig friend’s nose
  • Loves to socialize with humans or other guinea pigs
  • High-pitched squealing

When your cavy is angry, some of the ways they’re going to demonstrate this is by talking their teeth, purging in an angry voice, hissing, and exposing their teeth; they will do this to other cavies and humans.

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 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. 

#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 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 looks 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.

#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.

#7. Shrieking

The fairly unmistakable alarm, fear, or pain of a guinea pig is a cry, a loud rising squeak called a shriek.

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.

What Should I Do When My Guinea Pig Is Shaking?

If your guinea pig is shaking, you probably need to find the possible reason. One of which could be any significant change in the environment. Shaking after they were just adopted is quite common as they are stressed by this new transition.

In this case, you are advised to wait a little and let your cavy make itself comfortable. Usually, the issue resolves in some time as the guinea pig adjusts to the new environment.


Why do guinea pigs vibrate? There are various reasons that can make your guinea pig vibrate including happiness and fear. 

If you treat your guinea pig with kindness and reverence, the probability that your guinea pigs will vibrate with pleasure will be significantly improved.

Pet guinea pigs are active, curious creatures that can make excellent companions. Understanding what their actions mean is going to help you develop a better bond with your furry pet.
