The JW® Pet ActiviToy® Nutcase is a stretchy rubber football-shaped bird toy that hangs from a chain inside the cage. The soft, flexible rubber is durable and can be stretched and filled with your pet bird's favorite nuts or treats. Small cutouts in the rubber allow your bird to hold and manipulate the toy to remove the treats inside. The JW Pet Nutcase toy is both an intellectual and physical challenge for your feathered friend that helps activate your bird's body, mind and soul. Ideal for parrots of all sizes.
