Pigs need to be kept busy or they can become very vocal. I like to offer my pigs a ball pit to search for treats and this tunnel to run thru for exercise. Includes a pop up triangle tent, tunnel (red or yellow), a cube, and 50 soft plastic colorful 6 cm balls in a variety of colors. Netting bag is not included. Each component can be used together or separately. Easy to clean by a soft cloth, cold water & soap. Ideal for inside the home or in the backyard. Lightweight and portable with a zipper carry bag. Fast and easy set up and fold by pop-up design. Tent folds flat for convenient storage when not in use. Material: 100% Polyester fabric & spring steel frame.
