Unhappy Guinea Pig Noises: Signs of Stress or Pain

What you are hearing

Guinea pigs often hide discomfort, so unhappy sounds are useful clues. Some mean annoyance; others mean something is wrong.

Annoyance and stress sounds

• •Teeth chattering and hissing: anger or a warning.
• •High-pitched, short purring: irritation.
• •Whining or moaning: displeasure.
• •Grunting: mild protest.

Sounds that need closer attention

• •Squealing or screaming: check for injury or a fight right away.
• •Squeaking while urinating or passing droppings: possible pain.
• •Wheezing, clicking or crackling breathing: possible respiratory illness.
• •Sudden silence in a normally chatty guinea pig.

When to contact a vet

• •Any pain-related sound, breathing noise or loss of appetite.
• •Stress sounds that continue after you remove the obvious cause.

Sound in context

Sounds are only one clue. Read them together with body language, the situation and what is normal for your own guinea pig. Wheeky Identifier's Sound Translator can help you record and compare sounds, but a sudden change in vocal behavior alongside reduced appetite, fewer droppings or hunched posture needs an exotic vet, not an app.
