Cardboard boxes are the easiest chews to get your hands on because they’re practically lying around in every home!

They make great little hideouts for the guinea pigs and are also perfect for chewing.

So put a tiny hideout made from folded cardboard or throw in some wide scraps in their cage.

However, a drawback of using cardboard is that it can get wet pretty quickly, so you’ll be cleaning up some goopy mess from your guinea pig’s cage every now and then.

Paper rolls also make great chews if you don’t have anything strong or more durable at hand.

Rolled paper towels and bunched-up toilet paper stuffed with some hay are an absolute delight for guinea pigs.

Some guinea pig owners swear by this because it doesn’t break the bank and is totally safe to use, too.

Chewing objects give them the perfect opportunity to do just that. They need to grind their teeth down in order to maintain their health.

Even crunchy fresh vegetables are recommended for their diet to enable more grinding – and also to avoid the pigs from chewing on things like plastic or the metal cage.

To Beat Boredom Because They’re Active Animals

Guinea pigs are actually very active animals, which is why they’re usually bought in pairs so that they have company and entertainment.

A highly bored guinea pig will display signs of distress if it doesn’t get enough mental stimulation.

To provide your little piggy with enough chewing toys, especially if you have just one. This will keep them busy and engaged.

What also works especially well is if you play hide and seek with the chew toys!


With so many chewing options to choose from, your guinea pig should be busy for hours at an end and also have healthy teeth!

However, if you do notice a chipped tooth, do take your pig to the vet.

Also, make sure that the toys or chewable that you give to your pig don’t have sharp edges or splinters that could hurt their paws or gums – the idea is to provide the pig with a durable object to grind their teeth again.

It’s also a good idea to speak to your pig’s vet and find out what chewing objects work well for your pig depending on their age, size, and dental requirements.
