Why Is My Guinea Pig Squeaking So Much? What Each Sound Really Means

A grandmother came into the shop last summer with her seven-year-old granddaughter. The little girl had two guinea pigs at home — a pair of females called Pepper and Biscuit — and she had a very specific question that her grandmother clearly could not answer.

“Why does Pepper make that really loud WHEEK WHEEK WHEEK sound every time I open the fridge?”

I had to smile. It is one of my favourite questions.

I crouched down to the girl’s level and explained that Pepper was not distressed, was not in pain, and was not telling anyone off. Pepper was excited. She had learned — as guinea pigs learn remarkably quickly — that the sound of the fridge opening means vegetables are coming. And she was announcing, at full volume, that she knew exactly what was happening and she would like her share immediately.

The little girl thought this was the best thing she had ever heard. Her grandmother looked slightly less impressed at having been outshouted by a small rodent for the past several months.

I tell this story because it captures something I want every guinea pig owner to understand. Guinea pigs are vocal animals. They communicate constantly — with each other, with you, and apparently with your kitchen appliances. Each sound means something specific. And once you understand what you are hearing, the whole experience of keeping guinea pigs becomes richer, more interesting, and occasionally much funnier.

It also helps you spot the sounds that mean something is wrong — which is just as important.

The Main Guinea Pig Sounds — What Each One Means

Let me go through the sounds I get asked about most often in the shop. In my experience, these cover the vast majority of what owners are hearing and wondering about.

1. Wheeking — The Loud, High-Pitched Squeal

This is the sound most people think of when they think of a guinea pig. A loud, high-pitched WHEEK or WHEEK WHEEK WHEEK that carries across the room and, as Pepper demonstrated, can be triggered by the sound of a fridge opening, a rustling bag, or the specific footsteps of whoever normally feeds them.

Wheeking is almost always excitement and anticipation. It is the sound of a guinea pig that wants something — usually food — and is making absolutely certain you know about it. It is not a distress call. It is not pain. It is enthusiasm, expressed at considerable volume.

Guinea pigs learn the patterns of their household very quickly. If you feed them at the same time every day, they will start wheeking a few minutes before that time. If you always give them vegetables after opening the fridge, the fridge becomes a wheek trigger. If a specific person is the main feeder, the guinea pigs will wheek when they hear that person’s voice or footsteps.

This is intelligent, associative behaviour. It is a good sign — a guinea pig that wheeeks enthusiastically is a happy, engaged guinea pig that feels safe enough to be vocal.

2. Purring — The Low, Rumbling Sound

Guinea pigs purr — not exactly like cats, but with a similar low, rumbling vibration that you can sometimes feel as well as hear when the animal is sitting on your lap or being held.

There are two distinct purring sounds and they mean very different things, which is why this one can confuse owners.

The body language alongside the sound is always the key. A relaxed body with a low slow purr — all is well. A tense body with a higher, more staccato purr — the guinea pig is telling you something is not right.

3. Teeth Chattering — The Sound You Should Always Take Seriously

Teeth chattering is a rapid, clicking sound made by the teeth — you can sometimes see the lips moving slightly when it happens. It is distinct from purring and it means something specific and important.

Teeth chattering is a warning. A guinea pig that is teeth chattering is telling another animal — or a person — to back off. It is the guinea pig equivalent of a growl. The animal feels threatened, annoyed, or is asserting dominance.

4. Rumblestrutting — The Deep Rumble With Movement

This one makes owners laugh when I describe it, but it is a very real and very purposeful behaviour. Rumblestruting is a deep, continuous rumbling sound accompanied by a slow, swaying walk — the guinea pig moves its hindquarters from side to side while making the sound. It looks a bit like a very small, very self-important parade.

Rumblestrutting is dominance behaviour. A guinea pig that is rumblestrutting is asserting its authority — over another guinea pig, over a new animal in the enclosure, or occasionally over a human hand that has entered its territory.

Between guinea pigs, some rumblestrutting is normal and healthy — it is how they establish hierarchy. It only becomes a concern if it escalates into chasing, biting, or sustained harassment of a smaller or more submissive animal.

Rumblestrutting can also be a hormonal behaviour, particularly in unneutered males and in females during their hormonal cycles. If it is happening very frequently and seems to have no clear trigger, reducing light hours and removing nesting triggers can help.

5. Chutting — The Series of Short, Quiet Sounds

Chutting is a series of short, soft, rapid sounds — a little like quiet clicking or a subdued chattering. It is one of the sounds that owners often do not notice at first because it is quiet and tends to happen when the guinea pig is relaxed and exploring.

Chutting means the guinea pig is content and at ease. It is the sound of an animal going about its normal business without any particular concern. If you hear your guinea pig chutting while it explores, forages, or potters around, that is a genuinely good sign — it means the animal feels safe and comfortable in its environment.

6. Whimpering or Crying — The Sound That Needs Your Attention

This is the sound that should always make you stop and look. A whimpering, crying, or repeated distress squeal that is different from the excited wheek — longer, more sustained, higher in pitch, and not connected to food or excitement — is a sound that means the guinea pig is in pain, frightened, or in genuine distress.

A guinea pig making distress sounds should always be checked over carefully. Look for visible injuries, check for swelling or lumps, and assess whether the animal is moving and eating normally. If you cannot identify an obvious cause and the sounds continue, get to a vet the same day.

7. The Quiet Tooth Grind — Easy to Miss, Important to Catch

This is a soft, slow grinding of the teeth — different from the rapid chattering of a warning. It is subtle and easy to miss, and most owners only notice it when they are holding the animal close to their ear.

Slow tooth grinding, particularly if accompanied by reduced eating, drooling, or weight loss, is a sign of dental pain. Guinea pigs’ teeth grow continuously, and problems — overgrowth, spurs, misalignment — are very common, especially in animals that are not getting enough hay to wear the teeth down naturally.

If you hear or feel a slow grinding when you hold your guinea pig, and particularly if it is also picking up food and dropping it, losing weight, or eating less, this is a vet visit — dental problems in guinea pigs need to be assessed under sedation.

Why Is My Guinea Pig Suddenly Squeaking More Than Usual?

This is a question I get regularly, and it is worth addressing directly — because a change in vocal behaviour is always worth paying attention to.

A sudden increase in vocalisation is worth noting — not panicking about, but noting. If it comes with other changes in behaviour or health, act on it. If the animal seems otherwise well, monitor and see whether it settles after a few days.

Why Has My Guinea Pig Gone Quiet?

This is the question that concerns me more than “why is my guinea pig squeaking.” Because a guinea pig that has gone suddenly and noticeably quiet — when it is usually vocal — is a guinea pig that deserves a proper look.

Guinea pigs use vocalisation to communicate comfort, excitement, and engagement. A guinea pig that stops doing that has either become significantly stressed, unwell, or both.

If your guinea pig has gone quiet and is also eating less, moving less, or sitting hunched — please read our guide on guinea pig not moving signs and act the same day. Silence in a normally vocal guinea pig is one of the early warning signs that something is wrong.

What the Sounds Tell You About How Happy Your Guinea Pig Is

Right. Let me give you a simple summary — because after all of that detail, sometimes the practical picture is the most useful thing.

One Last Thing From Me

Guinea pigs are not silent pets. They are not background animals. They are social, communicative, genuinely characterful creatures that have a lot to say — once you know how to listen.

Every sound your guinea pig makes is information. The wheeking when you open the fridge. The deep purring when it sits in your lap. The teeth chattering when it has had enough. The quiet chutting as it explores its enclosure. All of it means something. All of it tells you something about how the animal is feeling and what it needs.

The owners who understand their guinea pigs best are not the ones who read the most books. They are the ones who watch and listen carefully every day — and who act when something in the pattern changes.

That is the whole of it, really. Watch. Listen. Act when something is different. That is good guinea pig ownership.

Frequently Asked Questions

Why does my guinea pig wheek when I open the fridge?

Because it has learned that the fridge opening means food is coming. Guinea pigs are remarkably quick to form these associations — the sound of a specific bag, a particular set of footsteps, the fridge door — and they wheek to announce that they know exactly what is happening and they are ready. It is enthusiasm, not distress.

Is it normal for guinea pigs to make noise all day?

Reasonably vocal guinea pigs are healthy, engaged guinea pigs. They tend to be most vocal around feeding times and when they hear familiar sounds associated with food or their owners. Some periods of quiet during the day are normal — guinea pigs rest in short bursts. Sustained noise throughout the day may mean the animals are not getting enough stimulation or are responding to something in their environment.

My guinea pig makes a clicking sound when it breathes — should I be worried?

Yes — a clicking or wheezing sound when breathing is a respiratory flag in guinea pigs and should be investigated the same day. This is different from the teeth chattering or vocalisation sounds covered in this article. Noisy breathing in a guinea pig can indicate a respiratory infection, which moves quickly and needs prompt veterinary attention.

Why has my guinea pig stopped making noise?

A guinea pig that has gone suddenly and noticeably quiet is worth checking over carefully. Silence can indicate stress, illness, or significant discomfort. If the quiet is accompanied by reduced eating, reduced movement, or a hunched posture, get to a vet the same day. If the animal seems otherwise normal, monitor closely over the next day or two.

My two guinea pigs are making loud noises at each other — is this a problem?

It depends on the sounds. Some teeth chattering and rumblestrutting between guinea pigs is normal dominance behaviour, particularly when they are first introduced or when the hierarchy is being renegotiated. As long as it does not escalate into sustained chasing, biting, or one animal preventing the other from eating or sleeping, it is usually self-resolving. If it does escalate, separate them temporarily and reintroduce more gradually.
