What Do Guinea Pigs Like to Chew On?

Guinea pigs have teeth that grow rapidly without stopping. As a result, they must constantly chew on things that grind their teeth to a comfortable length. A few things that guinea pigs love to chew on include hay, cardboard boxes, twigs, vegetables, and toys.


Since a guinea pig’s teeth are always growing, it’s crucial to their health and safety to ensure they have access to chewable materials to help them manage their tooth growth.

If their teeth are allowed to grow uncontrollably, it could lead to starvation, illness, and other health issues, including death. Fortunately, providing these things for piggy chewing doesn’t have to break the bank. There are plenty of low-cost and natural options to consider.

However, if you find yourself with a little extra cash to spare, there are plenty of guinea pig chew toys at your local pet store.

Chewables That Won’t Break the Bank


Our top pick of low-cost chewables for guinea pigs is cardboard! This includes toilet paper rolls (or the same roll that comes with paper towels) and shoeboxes. Not to mention that stack of cardboard that piles up on your doorstep every week.

Besides grinding their teeth into an easily manageable length, guinea pigs enjoy chewing on cardboard because it comes in so many shapes and sizes to keep things interesting.

Just make sure to give them clean cardboard that hasn’t been exposed to any chemicals.


Twigs are a great alternative and low-cost option if you do not have spare cardboard lying around.

Guinea pigs seem to enjoy twigs from fruit trees, including apple trees, pear trees, and other non-aromatic woods.

There are exceptions to this rule, though. It’s important to ensure that the twigs are free of any pesticides or chemicals before you give them to your furry friend. Before trying a new type of wooden twig, do your research to ensure it is safe.

Wood Blocks

Untreated wood blocks are also great options for a natural chewable for your guinea pig. If you have several wooden blocks that are large enough, they can be constructed to create a little hideout or tunnel for your guinea pig to not only snack on but also hide inside.

Snack Options

Guinea pigs can also manage the length of their teeth by grinding them on hay, vegetables, and fruit. Plus, these items double as snacks for your guinea pig in addition to its normal, everyday diet of guinea pig food/pellets.


Hay is a good choice for guinea pigs and should be offered in unlimited quantities to aid in grinding their teeth and to provide fiber, which helps with digestion.

The best types of hay that are helpful for your piggy’s digestive tract include timothy, barley, and grass hay. Straw is not recommended to replace hay because it does not offer the same nutritional benefit.


Guinea pigs also love vegetables, which are necessary for their diet. They should have a healthy amount of leafy greens every day, including cilantro, kale, romaine lettuce, and parsley.

Leafy greens have a high level of Vitamin C, which guinea pigs are unable to produce. You can also feed guinea pigs carrots, zucchini, red or green peppers, and sweet potatoes once or twice a week.


Guinea pigs also enjoy chewing on fruit. Just make sure it isn’t given too often as it contains a lot of sugar. Fruit can be given a couple times a week in small portions as a treat.

Fruits that are safe for guinea pig bellies are strawberries, kiwis, blueberries, bananas, and small pieces of apple or orange.

Start with an empty toilet paper roll. Create holes in the sides for wooden sticks to be poked through. Make sure, as previously mentioned, that the twigs or sticks are not aromatic and are safe for the guinea pig to chew on.

These not only keep your guinea pig’s teeth manageable, but they also keep the piggie happy, mentally stimulated, and entertained. Wicker tunnels and stands are fun for guinea pigs to explore, and if they get tired or hungry, there is always a snack nearby.
