Guinea pig litter box setup

The most common problem with guinea pigs’ behavior is that they do not want to use a litter box, which is understandable.

It all boils down to this: how will you make sure that your guinea pig uses their litter box? That could be accomplished by arranging your litter box in an appropriate manner.

Here are some of the steps you should take to properly set up your guinea pig’s litter box:

Add Hay

The chewing behavior of Guinea pigs is associated with willingness to perform a task. If there is litter in the box, placing a bunch of hay in it will increase the likelihood that a guinea pig will use their box.

It will also reduce the likelihood that your guinea pig will consume or eat the litter that has been provided for them to eat.

Don’t be concerned if you have to add the hay to the litter by yourself. As guinea pigs, they will not consume the stained hay, but they will enjoy the hay that has been set aside for them to chew.

Consider adding the hay, which should be 1 inch thick, to one section of the box. This hay must be used to fill at least one-third of the litter box in order to leave enough space for the litter.

Move the hay to one side

You can cut a piece of cardboard to fit around the length of the litter box to separate the hay from the litter for your guinea pig’s litter.

Clean the hay in the first section of the box with your one hand, using the cardboard, and then restore the other section of the box with the litter that you have been selected as the best of the bunch.

Remove the cardboard box from the measurement and allow it to settle evenly.

On the other hand, you can also place hay on top of the litter to keep it moist. It is possible that this will make the cleaning process more difficult because the hay will easily mix with the litter.

However, if you do not have a lot of space, placing the hay on top of the litter can be a lifesaver.

Add the litter

Put the guinea pig litter that you’ve chosen for your pet in this container. In addition, the litter must be spread to a thickness of at least 1 inch.

Those guinea pigs who enjoy digging can easily increase the thickness of the bedding by 2 to 3 inches. Because of this, the litter for your guinea pig must fill nearly two-thirds of the box’s capacity.
