Can Guinea Pigs Eat Cardboard? Know The Risks!

Can Guinea Pigs Eat Cardboard

You’ve probably noticed your guinea pig enjoys nibbling on various materials, and cardboard could be an enticing option for them.

It’s essential to know whether giving cardboard to your pet is safe or poses potential health risks.

Cardboard can sometimes function as an inexpensive and fun toy for guinea pigs. It is generally considered non-toxic and can provide mental stimulation and help wear down their ever-growing teeth.

However, it’s important to ensure the cardboard is free of any toxic substances, such as ink, glue, or other contaminants that could be harmful to your guinea pig’s health.

This article covers this in detail.

Can Guinea Pigs Eat Cardboard?

The answer to the question ‘Can guinea pigs eat cardboard?’ is generally yes – your pet can safely nibble on cardboard.

However, there are some important precautions to keep in mind. Here are some factors to consider when providing cardboard toys to cavies.

Clean and Unprinted

First, be sure that the cardboard you provide is clean, unprinted, and free from any chemicals or toxic substances. It should be clean and free from any harmful chemicals or dyes.

Opt for plain, brown, unbleached cardboard without any ink or glue. This will ensure that the cardboard you give your guinea pigs is as natural and safe as possible.

Not Their Main Diet

Additionally, don’t give cardboard as the main source of your guinea pig’s diet. Cardboard does not provide essential nutrients and is more of a supplementary item for your guinea pig to chew on.

Instead, ensure that your pet gets a well-balanced diet with high-quality hay, guinea pig pellets, fresh vegetables, and clean water.

In the Form of Chew Toys

While providing cardboard can keep your guinea pig’s teeth healthy – as their teeth constantly grow and need to be worn down – it should only be offered as an occasional chew toy.

If your guinea pig is losing interest in their other toys, you may opt for cardboard as a fun, cost-effective alternative.

Why Are Guinea Pigs Attracted to Cardboard?

Can Guinea Pigs Eat Cardboard


Guinea pigs are naturally curious creatures and love to explore and chew on various materials. One of the reasons they are attracted to cardboard is because of its texture.

Cardboard is relatively soft compared to other materials like wood, making it easier for them to chew and break down.

To Avoid Boredom

Another reason why guinea pigs are drawn to cardboard is that it provides mental stimulation. Chewing on the cardboard can help them stay entertained and engaged in their environment.

To Satisfy Their Natural Instinct to Chew

As a guinea pig owner, you might notice your furry friend spending hours nibbling on and playing with a simple cardboard box. This is a healthy way for them to satisfy their natural instinct to chew.

As Nesting/Resting/Hiding Areas

Your guinea pig might be drawn to cardboard not just for its chew-friendly texture, but also as a place to feel secure and rest.

Cardboard boxes provide a safe and cozy place for guinea pigs to hide and rest. In the wild, they seek cover to protect themselves from predators, so cardboard boxes and tubes mimic those hiding spots.

Benefits – The Good Side of Chewing Cardboard for Guinea Pigs

Keeps Teeth Trim

Cardboard can provide some benefits for your guinea pigs if given in moderation. Chewing on cardboard helps keep your pet’s teeth healthy and trim, as guinea pigs’ teeth continually grow throughout their life.


Additionally, cardboard can serve as a fun, engaging toy for them, keeping them entertained and mentally stimulated.

The Potential Dangers of Cardboard for Guinea Pigs

While there are some benefits to giving your guinea pigs cardboard, there are also a few risks to consider:

Choking hazard

If your guinea pig bites off too large of a piece of cardboard, it could potentially become a choking hazard. Monitor your guinea pig when providing cardboard as a chew toy and remove any large pieces if they break off.

Digestion issues

Although guinea pigs can technically digest small amounts of cardboard, it doesn’t provide any nutritional value. Consuming too much cardboard may cause digestive issues or blockages, so always provide plenty of fresh hay and healthy foods in addition to the cardboard.

Chemicals and toxins

Some cardboard may contain chemicals or toxins that could harm your guinea pig. As mentioned earlier, always choose plain, unbleached, dye-free cardboard to minimize the risk of exposure to harmful substances.

Remember to keep a watchful eye on your guinea pigs when giving them cardboard, and always ensure their environment is clean and safe. Providing a balanced diet and proper care is crucial to maintaining your guinea pigs’ health and happiness.

Safe Cardboard Types for Guinea Pigs

When choosing cardboard for your guinea pig to nibble on, it’s crucial to select safe options. There are a few types of cardboard that can be used as a source of entertainment and mild chewing for your little pets.

Plain, Undyed Cardboard

Firstly, opt for plain, undyed cardboard. Colored or printed cardboard may contain harmful chemicals or dyes that could be toxic for your guinea pig. Make sure the cardboard you use is free of any ink, glue, or other substances that could compromise your pet’s health.

Cardboard from toilet paper or paper towel rolls can be an excellent choice. These tubes are usually made of safe materials and are easy for your guinea pig to chew. Just be sure to remove any leftover tissue and clean the tubes before giving them to your pet.

Similarly, paper and paperboard used for food packaging can also be safe for your guinea pig to nibble on.

Small in Size

Cut the cardboard into small, manageable pieces that your guinea pig can pick up and chew without difficulty.

Monitor Your Guinea Pig

Keep an eye on your guinea pig, ensuring they’re chewing and not actually eating the cardboard. Swallowing large amounts of cardboard can create digestive issues.

Provide Other Safe Chews

Offer your guinea pig different types of safe materials to chew on, such as wooden chew toys or hay cubes. This will keep them mentally stimulated and engaged.

By providing your furry friend with safe cardboard options, you can enrich their environment and give them a fun way to engage in natural chewing behaviors, while ensuring their welfare.

How to Prepare Cardboard for Guinea Pigs

Remove Unsafe Materials

Before giving cardboard to your guinea pig, make sure to remove any unsafe materials such as tape, glue, staples, or stickers.

These can be harmful to your guinea pig if they chew on or ingest them. Peel off any labels or layers of cardboard that are coated with plastic, as this material can also be dangerous for your pet.

Keep It Clean

Before offering cardboard to your guinea pig, ensure it is clean and free of dirt, dust, or any other contaminants.

Use a damp cloth to wipe down the cardboard and allow it to dry thoroughly before giving it to your pet. Additionally, avoid using cardboard that has been exposed to strong-smelling substances, as the odor could be harmful to your guinea pig’s sensitive respiratory system.

Alternatives to Cardboard Chewing

Instead of using cardboard as a chewing material for your guinea pigs, you should consider providing them with safer and healthier alternatives.

Hay-Filled Tubes

One option, that is both entertaining and beneficial, is offering hay-filled tubes. Hay-filled tubes aren’t just great for chewing, but they also help in keeping their teeth in check and encourage their natural foraging behavior.

Wooden Chews

Another alternative to satisfy your guinea pigs’ need for chewing is providing them with wooden or pumice stone chews.

These materials are durable and can help maintain your pet’s dental health. Additionally, they come in various shapes and sizes, which adds fun and variety to your guinea pigs’ environment.

Vegetables and Fruits

Consider introducing fresh and leafy vegetables into their diet as well. Vegetables like kale, romaine lettuce, and dandelion greens not only give them something to chew on but also supply essential vitamins and minerals for their overall well-being.

Add Some Enrichment in their Cage

Lastly, it’s not a bad idea to incorporate environmental enrichment into their living space. This can be achieved by providing toy balls made from natural materials like willow or adding hiding spaces like igloos or caves.

These toys can keep your guinea pigs engaged and provide additional chewing opportunities.
