*** Wheel of Fortune has been selected as the winner of the Cat Toy of the Year award! *** This game poses a new challenge for your pet. Unlike flat board games, where your pet has to move pieces with his nose or paw to get a reward, this game requires your pet to spin the wheel vertically. The cylinder has four segments separated by thin wooden walls, each with holes. Three segments have holes with a diameter of about 10 mm (they will not let the recommended treats fall out) and in one segment holes have a diameter of about 12 mm - they are big enough to let the treats get through. Once the wheel turns, treats fall out. An opening on the side of the cylinder is used to refill the wheel with treats. The size of the treats should be carefully selected so they can easily fall through the bigger holes.
