The Parallax Colour Merge Hay Play is the original and popular hay play, now available in two colour options featuring a blend of the original colours. Its unique design, with thirty-two flat faces, allows the feeder to roll around as the horse grazes from it. The movement of the hay play challenges and entertains the horse, offering all the benefits of slow feeding without the need for additional treats or feed. Its single-piece construction makes it incredibly strong and durable.
