Pigs love to play and have fun outside but sometimes they need to use the restroom. When you leave for school or work you can't take him out. In their room they need to have a place to use the restroom.
Litter- For their litter they need to have pine smelling chips because they are naturally attracted to pee/poop on pine. We learned the hard way when he started peeing and pooping on our Christmas tree. It's better to clean it out once a day otherwise it get's messy.When we got ours since we had the pine chips it just peed on that but as he got older he just started pooping everywhere upstairs so we closed it off and everything went back to normal. What I found weird was that he didn't poop randomly downstairs. But anyway to clean out his poopy box I first pour out all the chips. Secondly, I take some paper towels and dry up all the pee. Then I take any wipe and wipe it just in case. Next, i fill it back up with pine chips. Finally, I stick it back in his room.
