Hamsters love to chew on wood, food, and cage bars, but is cardboard safe for them to chew on?
Can Hamsters Chew On Cardboard? Hamsters can chew on cardboard as long as nothing could potentially hurt the hamster is on the cardboard, such as printing ink, metal staples, glue, and tape.
Before you go tossing any old cardboard into their cage, you need to make sure the cardboard you’re giving them is safe and free of any toxins or dangerous attachments.
How to Make Sure the Cardboard is Safe
While cardboard itself is safe for your hamster to chew on, things are often attached to cardboard that can harm your furry little friend.
Before you give your hamster any cardboard, you should check for the following hazardous items:
These are by far the most dangerous cardboard attachment, as your hamster can attempt to chew them and cut themselves in the process.
Glue and other adhesive substances.
While useful for humans, these substances can be composed of dangerous chemicals. If your hamster eats them, they can get quite ill.
You’ll want to remove any tape on the cardboard because it can be difficult for your hamster to digest. The chemicals used to make the tape sticky can also be toxic.
There are a number of food items that can make your hamster sick. If one of these types of food is on the cardboard you give your hamster, your furball could get sick.
Glossy or dyed cardboard.
While most cardboard is okay for your hamster to chew on, glossy or dyed cardboard is not okay. The chemicals contained in these special types of cardboard can be toxic to small animals.
Don’t worry too much if you accidentally give your hamster something from that list, though (except for the staples – those are not okay). Hamsters are pretty good at knowing what food  is and what isn’t.
If you give them some tape or glossy cardboard, they almost certainly won’t eat it. They’re just looking for something firm to gnaw on.
It would be best if you didn’t worry about giving your hamster colored cardboard. Again, they probably aren’t going to eat it, so the minimal amount of chemicals in the cardboard coloring should be a non-issue.
If you want to play it safe, though, you can stick to giving your hamster plain old brown cardboard.

Why Does My Hamster Want to Chew Cardboard?
The main reason your hamster likes to chew on cardboard (and everything else) is that its front teeth, also known as incisors, never stop growing.
Evolution has given them a constant instinctual urge to gnaw on things constantly. By doing this, they can keep their incisors from growing too long .
Take a look at the video below to see a cute hamster biting cardboard.
It’s imperative that they keep their teeth at a reasonable length. If their incisors aren’t kept in check, they can interfere with your hamster’s ability to close its mouth.
This has all sorts of adverse health implications :
- An inability to eat
- Cuts in the mouth and on the gums
- Extreme pain when the upper and lower incisors inevitably strike each other
- Broken teeth from improper chewing on hard objects (like cage bars)
Your hamster also likes to chew on cardboard because it makes for excellent nesting material.
Unlike most other materials available to a hamster in its cage, cardboard is easily broken down into smaller pieces and makes the perfect nesting material.

Health Benefits Of Chewing Cardboard
The primary health benefit of chewing cardboard is that it will keep your hamster’s incisors at a healthy length.
In addition to saving your hamster from painful cuts, they will also keep eating their healthy pellets and veggies.
Which will, in turn, keep them healthy and free of illness.
It’s all cumulative… so make sure you give your hamster plenty of things to chew on!
It can also keep your hamster occupied, though, which can help keep your hamster from becoming bored or depressed.
This is honestly a pretty minor detail, as most hamsters will find plenty to do whether they have cardboard or not.
But it’s an extremely inexpensive way to add another fun activity to your hamster’s life, so you might as well throw some cardboard in their cage.
