a tip that explains that guinea pigs can eat certain types of paper in small amounts
Do not feed paper to your piggies as a meal. They can’t digest huge amounts of paper.

  • The type of paper you give your little friends (newspaper, paper plates, tissue paper, etc)
  • The size and thickness of the paper
  • The frequency at which your cavies eat the paper
  • Whether or not there is ink on the paper
  • What type of ink is on the paper

You don’t have to panic that your cavies are gnawing on cardboard or cereal boxes. Many types of paper are safe for guinea pigs to eat (in small amounts).

Paper is made from plants (hello, cellulose). So, they’re basically safe for cavies to chew and even eat in moderate amounts. But, you need to remember that papers aren’t actual, fresh food, so they don’t provide any nutritional benefits to cavies.

Apart from helping them kill boredom, the paper helps keep cavies’ teeth at ground down. Guinea pigs’ teeth don’t stop growing.

So, your little friends need something to gnaw regularly to make sure their teeth don’t overgrow. Apart from hays, different types of paper products be a great way to keep their teeth at a manageable length.

Will Eating Paper Hurt My Guinea Pig?

a sarcastic guinea pig wondering if he can eat paper
Most plain types of paper are safe for piggies to nibble on occasionally. But, you need to make sure that your little friends eat much more hay and veggies than paper.

Eating papers will hurt your guinea pigs if they eat too much. Paper (or paper products) should never be a meal alternative, just something for them to have fun with and nibble on from time to time.

Most piggies can safely digest small amounts of paper. Overeating papers can cause the following issues with your little friends:

1. Bloat

Their intestines may be blocked from eating excessive paper. Since cavies’ system can’t break down large amounts of paper into something useful, it can block their intestines and digestive system.

This’ll start a domino effect of issues. Because a blocked intestine leads to bloat in guinea pigs. And bloat is a serious condition that can quickly kill your cavies if left untreated.

2. Constipation

There are a number of things that can cause constipation in cavies, and eating too much paper. Huge amounts of paper isn’t easily digestible, and it can cause blockages in the intestines. This can lead to discomfort and even pain for your little friends.

When cavies are constipated, they usually stop eating and can’t poop. Unable to dispose of waste (poop) or eat, they experience pain all over their body. Chronic cases of constipation can be deadly for your fur babies.

If you think your guinea pig may be constipated, take them to the vet for an exam. In the meantime, try to avoid giving them any paper to eat.

3. Malnutrition

After having constipation, their feeding pattern is undoubtedly affected. Your cavies won’t be able to feed on hay, fruits, or vegetables because of being full.

And if they’re not eating fresh, raw food that’s good for them, then your piggies are missing out on important nutrients that they need to stay healthy and to live long lives.

Guinea pigs need Vitamin C to prevent Scurvy, fiber to digest food, calcium to help bone strength, vitamins to build the immune system, and iron to boost metabolism. If they don’t have the essential nutrients they need (daily), your fur babies’ health will go down very quickly after a few days.

Why Do Guinea Pigs Eat Paper (Or Paper Products?)

Cavies may gnaw, eat, or nibble on paper because they enjoy playing with it or because they’re genuinely hungry. Sometimes, they may eat paper due to fiber deficiency or to help rebalance their gut (like after being sick). Finally, boredom will cause guinea pigs to eat paper, too. Actually guinea pigs might eat anything chewable that comes their way for the reasons above. 

How Do You Stop Guinea Pigs From Eating Paper?

There’s a few different things that you can try to keep your piggies from eating too much paper. Remember it’s okay for guinea pigs to gnaw and nibble on paper, but eating tons of it isn’t good for their health.

Let’s take a look at a few tips:

1. Change Their Paper Beddings And Lining

Out of sight; out of mouth…mind…whatever. Instead of using paper, change their beddings and lining to other materials. There’s plenty of affordable ways to line your guinea pigs’ cages.

Fleece liners and noodle bath mats are popular options. Wood pellets or wood shavings (like aspen or kiln-dried pine) are safe to use as well.

This way, they won’t have any paper available in their vicinity to chew, and you’ll be able to easily monitor their eating habits.

2. Provide Toys and Activities

If your guinea pigs are constantly bored, they may start looking for things to do–and that includes eating paper.

Luckily, there’s plenty of toys and activities you can provide them to keep them entertained.

Some piggie favorites include:

  • tunnels
  • treat balls
  • cardboard boxes
  • willow balls
  • mirrors
  • Oxbow brand toys

Your piggies will be busy all day with enough stimulation. Therefore, they won’t have time to eat paper even if it’s within their reach. Besides, cavies gnawing on toys are an excellent alternative to keep their teeth at bay. 

3. Offer Better Hays

Sometimes, guinea pigs’ chewing of papers may result from hunger or fiber deficiency.

Make sure that your little friends have unlimited access to as much hay as they want. The hay pile shouldn’t ever run low. Otherwise, your little friends will grab the roughage from wherever they can get it – including paper.

Timothy hay (or any other high quality hay) is the best and fiber-rich hay option. Make sure your cavies enjoy the optimum fiber level from eating hay.

4. Get Them A Friend

Cavies are social animals. This means that when they are alone for too long, they get bored. Boredom can lead to them chewing on papers (and eating too much paper), which isn’t good for them.

But, you can get them a friend to beat boredom. Most piggies would love a piggie cage mate or neighbor to talk to and play with. By being routinely engaged, your fur babies are less likely to be focused on chowing down on paper.

Why Has My Guinea Pig Suddenly Started Eating Paper? 

If your guinea pig has suddenly started eating paper, then it could be for a couple of reasons. If your little friend has been sick, eating the roughage of paper (and paper products) might help bring their guts back into balance. If your piggie has recently become a solo piggie, then they might be experiencing loneliness and boredom which are both contributing factors to why they’re eating paper.

All is not lost if your guinea pig is eating too much paper. With some simple changes and vigilant monitoring, your furry friend can get back to their healthy ways in no time.

As a responsible piggie parent, it’s important to be aware of the reasons why your guinea pigs may be eating paper. Although gnawing on paper is normal and healthy for cavies, please remember that overeating paper can cause health problems.

And if you have piggies that LOVE eating paper, having paper bedding isn’t the best idea. Literally, it’s going to be in their face…everywhere. Your piggies aren’t going to not, not eat it. They’d have a field day.
