This is a fun activity mat to keep your pig busy. I prefer using this mat when I travel to places especially to the Vet since it's a smaller size. This mat works great in a smaller pen where you don't have as much room.
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. Pigs love games and activities.
Please always watch indoor pigs with any fabric, cloth, cotton, blankets with a lining, strings, carpet, fuzz, small parts, etc.. It's virtually impossible to shield them from everything but proper care should avoid any issues.
