This Rabbit Hay Bag changes the way you feed your rabbits, hamsters, and Guineas. To avoid a feeding frenzy, this hay bag holds the hay and dispenses only what your rabbits can consume. So, the cage is less-messy and you also train your rabbits to feed properly. It’s a polyester bag with a wide top opening with two or four feeding holes. Designed with two hooks so you can easily anchor it to the cage.
