Do guinea pigs need hay feeders? - Brooks-Falls Veterinary Hospital
They don't need hay feeders. You can just put the hay down on the bottom of the cage, and they can access it just fine. They don't need it to be up in a fancy holder. I tried a fancy holder, and my guinea pig just snapped it right on the side of the cage, and then I spent the majority of the time picking it out of the carpet.
