Guinea pigs are amazing cute little pets, and ours at Piggy Playground brings so much happiness into our lives. One of the most satisfying parts of being a guinea pig owner is witnessing their unique behaviors that signal happiness, like seeing them happily chewing away on their toys.
But, many owners notice their guinea pigs taking a bite out of cardboard. Whether it’s a toilet roll tube or a hidey house box, piggies seem to love sinking their teeth into it. This often leads to the question: Can guinea pigs eat cardboard? Is it safe?
If you are wondering whether it is safe for your furry friend to munch on paper products, this guide is for you. Understanding their behavior helps you create a loving environment for them.

Is cardboard safe for guinea pigs to eat?
The short answer is yes, in moderation.
Cardboard is generally safe for guinea pigs to chew on and ingest in small amounts. It is essentially wood pulp (cellulose), which is a form of fiber. Since guinea pigs are herbivores who need a lot of fiber in their diet, a little bit of cardboard won’t hurt them.
However, it shouldn’t be a meal. While it isn’t toxic, it provides zero nutritional value compared to their essential diet of hay and fresh vegetables. Feeding your guinea pig the right diet is crucial for their happiness and well-being, so think of cardboard as a chew toy, not a snack.
Guinea pigs require a balanced diet full of essential nutrients. Understanding what they need helps you keep them healthy and happy. Their diet should mainly consist of hay, fresh veggies, and high-quality pellets.
WHY DO THEY CHEW CARDBOARD?
You might wonder why they find a brown box so delicious. It usually comes down to two main things: dental health and entertainment.
WEARING DOWN TEETH
Guinea pig teeth never stop growing. To keep them at a comfortable length, they need to chew on rough materials constantly. Apple sticks and willow balls help them wear their teeth down, but cardboard offers a similar resistance that feels satisfying to gnaw on.
BOREDOM AND FUN
Providing activities and enrichment is essential for keeping your guinea pig happy and healthy. A plain box can be a very exciting toy for a piggy! They might chew on it to customize their “furniture” (making a door wider, for example) or simply because tearing things apart is fun.
SAFETY CHECKLIST: WHAT CARDBOARD IS OKAY?
Not all cardboard is created equal. Before you toss a box into their cage, you need to make sure it is safe.
REMOVING TAPE AND GLUE
Standard shipping boxes often come with plastic tape, staples, or heavy glues.
- Tape/Plastic: This is a major choking hazard and can cause intestinal blockages. Always peel every bit of tape off.
- Staples: Metal staples can injure their mouths or eyes. Remove them completely.
- Glue: While some vegetable-based glues are okay, industrial chemical glues are not. Avoid boxes that are heavily glued together.
AVOIDING INKS AND DYES
Plain brown cardboard is best.
- Glossy/Shiny Cardboard: Avoid anything with a shiny, plastic-like coating (like cereal boxes). This coating is not safe to digest.
- Heavy Inks: Boxes covered in bright, colorful inks might contain toxic chemicals. Stick to plain brown rolls or boxes with minimal printing.
FUN WAYS TO USE CARDBOARD
We love using cardboard because it is a free and easy way to enrich your pet’s life. Here are some of our favorite ways to use it.
TOILET ROLL HAY TUBES
You can stuff hay into toilet rolls to make a fun feeder.
- Safety Tip: Just split them down the middle to avoid their heads getting stuck. This is a common issue, and cutting a slit ensures they can pull their head back out if they get too curious.
DIY HIDES
You can also make hides out of cardboard boxes. Cut a couple of archways into a plain delivery box, flip it over, and you have an instant castle. These allow your guinea pig to feel secure while also providing a place to explore.+1
WHEN TO STOP THEM
While chewing is fine, eating the whole thing is not.
If you notice your guinea pig is devouring the cardboard rapidly rather than just shredding it, you should remove it. Consuming large amounts of cardboard can cause a blockage in their gut because it doesn’t break down as easily as hay.
If you notice your guinea pig isn’t eating their normal food, or sits in the corner alone a lot more than often, make sure to take it to a vet ASAP as these are signs of some common illnesses in guinea pigs.
What other things can guinea pigs safely chew on?
There are some other things your guinea pig can chew on safely. That are less likely to cause a health risk if they eat tons of it.
We recommend looking for non-toxic, natural options that promote healthy chewing.
Some safe alternatives include:
- Wooden chew sticks: Ensure they are untreated and safe for small animals.
- Timothy hay cubes: These provide fiber and help with dental health.
- Chinchilla chews: Many are safe and made from wholesome ingredients.
Always supervise your guinea pig while they chew. This will help prevent any accidental swallowing of unsafe materials. By choosing the right options, you can keep your furry friend happy and healthy!
Risks of Guinea Pigs Eating Cardboard
While cardboard might seem harmless, there are important risks to consider when it comes to your guinea pig’s health. Eating cardboard can lead to serious health issues, especially affecting their digestive system. Here are two main concerns to keep in mind.
Potential for Intestinal Blockages
Your guinea pig’s digestion relies heavily on plant-based foods. While they may chew on cardboard, swallowing it in large amounts can be dangerous. If ingested, cardboard can cause intestinal blockages.
Signs of an obstruction include:
- Lethargy: Reduced energy or activity.
- Loss of appetite: Not wanting to eat or drink.
- Abdominal swelling: A noticeable bulge in their belly.
These symptoms require immediate veterinary attention. Intestinal blockages can be fatal if not treated quickly. Always monitor your pet to ensure they avoid swallowing too much.
Impact on Digestive Health
Guinea pigs are herbivores, which means their digestive systems are designed for fiber-rich foods. Cardboard is tough and not meant for their diet. Regular ingestion can lead to digestive issues like:
- Diarrhea: Loose stools can signify a digestive upset.
- Bloating: Excessive gas build-up that can cause discomfort.
The rough texture of cardboard can irritate their stomach and intestines. Keeping your guinea pig on a diet rich in hay, vegetables, and pellets will support their gut health better than cardboard ever could.
Creating a Stimulating Environment
Your guinea pigs need a fun and safe space to thrive. Providing the right cage size, bedding, and a variety of toys and fresh foods ensures they stay happy and mentally engaged. Here are some key points to enhance their environment.
Appropriate Cage Size and Bedding
Make sure your cage is spacious enough for your guinea pigs to move around comfortably. A minimum of 7.5 square feet is ideal for two guinea pigs. This allows them to explore and play without feeling cramped.
Choose bedding that keeps your piggies safe and clean. Safe options include aspen shavings, paper-based bedding, or grass mats. Avoid cedar or aromatic wood shavings, as these can harm their health. A clean, soft surface helps them feel cozy and encourages natural behaviors.
Offering a Variety of Toys and Fresh Foods
Guinea pigs love to chew, so offering them toys made from cardboard, wood, or hay is a great way to keep them entertained. You can make DIY toys using cardboard tubes and boxes. These can stimulate their minds and satisfy their need to chew. Be sure to supervise their play to prevent any overconsumption of cardboard.
Fresh food is also vital. Provide a mix of leafy greens and vegetables daily. This not only keeps them healthy but adds variety to their diet. Remember, social animals like guinea pigs thrive when you engage with them regularly. Playing together or simply spending time with them can elevate their happiness.
