The Food Ball protects food from soiling and makes small pets work for their meals in a playful fashion - just watch your pet crane and stretch to try and get at the tasty treats inside. As well as the height, the ball swings around on the end of its chain, keeping pets busy even longer. A great toy for all small pets (except hamsters).
