If you don’t want the guinea pig to eat the bedding, there should be enough toys in the cage.

Toys are an important part of a guinea pig’s life when living in a cage because they reduce stress and maintain their teeth.

Toys for guinea pigs are made to be chewable which reduces problems with their teeth. You can buy various types of toys such as balls, chew tunnels, and many other toys at pet stores.

The more toys there are in their cage, the less likely the guinea pigs will eat the bedding.

Another guinea pig

If you only have one guinea pig then you should play with your pet and take some time to spend with him.

The more the guinea pig is socialized the less it will eat the bedding.

If you keep two guinea pigs and they start fighting, then put them in separate cages, but put them next to each other so they can still be close to each other.


Guinea pigs’ teeth are constantly growing and if there is nowhere to reduce them, they will start eating the bedding.

Therefore, they should have enough toys and eat hay so that they do not need to eat bedding.
