Guinea pigs are highly social and very vocal. Understanding your pig’s sounds can help you know your pig better. Guinea pigs are known for their ubiquitous squealing and wheeking. Sometimes it’s a cry for attention or to make you alert to something he notices. You can also anticipate a very animated and urgent series of squealing and wheeking when it’s mealtime, starting as soon as you start gathering your pig’s food together. Pigs also make a purring sound to indicate that they are comfortable and content. Your pig may also make a little murmuring or clucking kind of sound when he is busy or preoccupied in the cage. He is happy exploring. All of these are good sounds. However if you hear a loud shriek, your guinea pig may be in pain or very frightened. Check on him immediately.
