Rooting Box: This is a great indoor activity. Appropriate items for a rooting box are ANYTHING safe, big enough to not swallow, not sharp, ect. Many use play pit balls, river rocks, large stones, stuffed animals, an assortment of toys, blankets, newspaper, anything your pig can search through will work fine. For the box itself, it can be an actual wooden frame, a plastic tub small kiddy pools work great, some people put the rooting objects into a dog crate to keep things contained.
