Guinea pigs can be trained to do some basic actions, such as using a litter box. It takes a little patience, but is a very satisfying form of interaction with your pets. Some guinea pigs are smarter than others, so don’t be angry if your pet never quite gets the hang of it.
Guinea Pigs can be trained - to a certain extent
Collect some of your guinea pigs' favourite treats to give them a strong incentive to learn, and keep repeating the training for a few weeks to give your pets plenty of practice.
