Understanding Guinea Pig Chewing Behavior

As a guinea pig owner, you may notice that your pet loves to chew on just about anything. This is because chewing is a natural behavior for guinea pigs and serves several important purposes.

First and foremost, chewing helps to maintain your guinea pig’s dental health. Guinea pigs’ teeth are constantly growing, and chewing helps to keep them trimmed and healthy. If they don’t chew enough, their teeth can become overgrown and cause dental problems.

Secondly, chewing is a form of enrichment for guinea pigs . In the wild, they would spend a lot of time foraging for food, which would involve a lot of chewing. Giving your guinea pig appropriate things to chew on can help to prevent boredom and provide mental stimulation.

So, what do guinea pigs like to chew on? Generally, they prefer things that are slightly rough and fibrous, such as hay, wood, and paper. They also like to chew on things that make noise or have interesting textures, like cardboard tubes or crinkly paper.

It’s important to provide appropriate things for your guinea pig to chew on, as they can become frustrated and bored if they don’t have access to these materials. In the next section, we will explore whether cardboard is a safe material for guinea pigs to chew on.

Is Cardboard Safe for Guinea Pigs to Chew?
