Guinea pigs communicate through a remarkably diverse vocabulary of vocal squeaks, purrs, and physical postures. Decoding their language helps you respond to their emotional state and spot stress early.
1. Primary Vocalizations Explained
📢 "Wheek! Wheek!" (Excitement / Food Request)
A loud, high-pitched whistle. Cavies rarely wheek to each other in the wild; they developed this signal specifically to request fresh veggies or hay from human owners when they hear a fridge door open or food bag rustle.
🎶 High-Pitched Purr or Chutting (Contentment)
A soft, rhythmic bubbling sound made while exploring, munching hay, or enjoying gentle chin scratches. Signals safety and relaxation.
⚡ Teeth Chattering / Clacking (Warning / Anger)
Rapid, harsh clicking of teeth. This is an explicit warning signal meaning "Back off!" or "I am agitated."
2. Fascinating Body Language
- Popcorning: Sudden jumping straight up into the air with 180-degree twists. A sign of pure joy, commonly seen in young cavies.
- Rumblestrutting: Walking slowly with a low purr and swaying hips. Used by boars (and dominant sows) to establish herd hierarchy.
- Freezing: Standing completely motionless with eyes wide. Prey defense mechanism when startled by sudden noise.
Key Takeaway
Wheeking and popcorning mean pure joy; teeth chattering and head-raising warn of annoyance or conflict.

Teeth chattering is a clear warning sign meaning "back away." If your guinea pig chatters at your hand or another cavy, give them space to de-escalate.
Why do guinea pigs popcorn?
Popcorning—jumping and twisting erratically into the air—is an involuntary reflex of intense happiness, playful energy, and contentment.
