Mini Pigs, contrary to most people's beliefs, are very clean animals. By the time they are a few weeks old, piglets will follow their momma to the litter box for potty breaks. Unlike most other animals they would prefer to use the bathroom outside of their sleeping quarters. When you first bring home your piglet, ensure they have easy access to a litter box. It is important to remember they are still just a baby and will have an accident if they are given a large space to roam around and no litter box near by.
