Lots of people don’t know that it’s actually possible to partially train guinea pigs to do their business in a litter box. Owners have a range of different levels of success with their pets, some taking to it quickly, some never learning no matter how hard their owners try. You may not be successful, so be sure to remember that it’s not your guinea pig’s fault if they poo outside their litter box - sometimes they can have accidents or just simply forget.
Some guinea pigs can be trained, whereas others might not be able to learn
If you want to give it a try, buy a small mammal litter box and put in some bedding into it. Avoid anything like cat litter, as this could be harmful to your pet. Instead, we suggest trying some fresh bedding, or putting in some used bedding to make the area smell familiar to your guinea pigs. If you are training using old bedding, make sure the litter box isn’t so dirty that they won’t want to sit in it. Another tip is that if you’ve noticed that your guinea pig likes to do their business in a particular place, then that area may be an excellent spot for your litter box.
If you keep an eye on your guinea pig and notice it going in the litter box, then immediately reward it with a treat. This will create an association between using the litter box and being rewarded, which will increase the likelihood that your guinea pig will perform that action again. However, not all guinea pigs will be able to do this, so don’t be disappointed if you’re not successful.
