Despite being marketed as a tunnel for mice, here at HayPigs! we have found a much more exciting use for this understated little product. This hollow bark tube features a serious of circular holes cut out of it that are just perfect for presenting your small furries with hay, forage and other treats! If you want that natural look and to provide something that can also be nibbled at safely, this might just be the product for you! We find them very handy!
