JW Pet Bird Insight Activitoys nutcase treat-dispensing toy is a stretchy, rubber football-shaped bird toy that hangs from a chain inside the cage. The soft, flexible rubber is tough and can be stretched and filled with your pet bird's favourite nuts or treats. Small cut-outs in the rubber allow your pet bird to hold it and to manipulate the toy to remove the treats inside. The JW Pet Nutcase toy is both intellectually and physically challenging to your feathered friend that helps to activate your bird's body, mind and soul. Great for parrots of all sizes.
