Why Is My Guinea Pig Making That Noise?

Guinea pigs are popular pets for good reason - they’re social, expressive, and surprisingly vocal. If you've ever stopped to wonder what all those squeals, purrs, and clicks mean, you're not alone.

Guinea pigs use sound as a primary way to communicate how they're feeling. Understanding these noises can help you care for your pet more effectively and strengthen your bond in the process.

Here’s a breakdown of the most common guinea pig sounds and what they usually mean.

Wheeking (Whistling or Squealing)

Wheeking is one of the most recognizable guinea pig sounds. It’s a loud, high-pitched whistle or squeal, and it usually means one thing: food. Many guinea pigs start wheeking when they hear a bag rustling or the fridge door opening. It's their way of saying, "Hey, don't forget me!"

• What it means: Excitement or anticipation - especially about treats or mealtime.
• When you’ll hear it: Right before feeding, or when they expect a snack.

Purring

This one can be a little tricky, because the meaning depends on how it sounds and the body language that comes with it.

• A low, soft purr, especially when your guinea pig is relaxed or being petted, signals contentment.
• A high-pitched or tense-sounding purr, paired with a stiff posture, can mean they’re irritated or uncomfortable.
• What it means: Calm happiness or mild annoyance.
• Tip: Always consider the situation - are they lounging calmly or frozen in place?

Chutting and Whining

“Chutting” is a quiet, repetitive clicking or chattering sound. It’s often heard when a guinea pig is walking around, sniffing, or exploring.

• What it means: Curiosity or calm interest.

Whining, on the other hand, sounds more like a drawn-out moan or a high-pitched complaint. It's a sign they’re annoyed or want to be left alone.

• What it means: Mild irritation or discomfort - often directed at another guinea pig or a person who's overstaying their welcome

Teeth Chattering

This is a clear warning sign. If your guinea pig is rapidly grinding its teeth together, it’s not happy.

• What it means: Aggression, stress, or a warning to back off.
• When you’ll hear it: During tense moments between guinea pigs, or if your pet feels cornered or threatened.

If teeth chattering happens during play or feeding time, it's a good idea to monitor the interaction closely - or separate pigs if necessary.

Screaming or Shrieking

This is the sound you never want to ignore. A loud, piercing scream or shriek usually means your guinea pig is scared or in pain.

• What it means: Extreme distress, injury, or fear.
• When you’ll hear it: If they’ve been hurt, trapped, bitten, or startled.

If you hear this sound, check on your guinea pig immediately to make sure they’re safe and uninjured.

Listening Makes a Difference

Guinea pigs may be small, but they have big personalities - and plenty to say. By tuning into their sounds and watching their behavior, you’ll get a better sense of how they’re feeling and what they need. Whether they’re asking for a snack or warning off a cage mate, each sound is part of their unique way of talking to you.
