Pig rooting mat. Or "snuffle" mat as people call it. Pigs require physical and mental stimulation to meet their needs. This rooting mat is perfect. Rooting/nudging is a natural behavior and shouldn't be discouraged. I like to throw pellets in this mat and let my pigs root away. It's also a great distraction when I leave the room.
