It’s called “wheeking” because it sounds like the word. Your guinea pig may use this noise to beg for food, especially if it hears a noise that means food could be on the way, such as the refrigerator opening or bags crinkling.

You may hear this sound when you’re feeding it or petting it, for instance. Be careful to distinguish this sound from the “drrr, drr” sound below.

You might also hear this noise when your pet is checking out a new toy.

Other guinea pigs may take this as a warning sound and freeze.

The squeaks that accompany this teeth chattering will sound angry. It can sound like hissing.

Try petting your guinea pig and speaking to it in a gentle voice when it makes this sound. If your guinea pig is making this noise when being pet, they are telling you that they have had enough petting for now.

Guinea pigs may make this sound when one is pursuing the other, and either guinea pig may make it.

For instance, some guinea pigs don’t like to be pet down their back. They may make this noise when you hit their tailbone. [9] X Research source

This noise could also be described as squealing.

This can show they’re excited about something, like a treat, or it can just mean they want to play.

Your guinea pig may make a little vibrating noise as it freezes.

You may also notice your guinea pig is lethargic or is making loops around the cage. This behavior can indicate an injury, but it also may mean your guinea pig is bored. It may need more time outside the cage or more toys to keep it entertained.

It may also use its rear end for this purpose.

On the other hand, licking you can be a good sign.

You may also notice your guinea pig trying to dance for a female. Typically, the dancing consists of the guinea pig wiggling his back end back and forth.

Also, a sick guinea pig will likely refuse to eat or drink, and it may have bloody urine or loose stools. Your guinea pig may also make coughing noises. [18] X Research source
