Review on Timothy Hay Tunnel by Oxbow Animal Health by Kelsey Hoss

I received this as a shelter/tunnel for my American Shorthair and Abyssinian guinea pigs. They seem to like it. I also like two guinea pigs living together because they can't corner each other when they fight. Sometimes I like to fill it with hay and they like to bury themselves in it and eat their hay. The tunnel is made of braided grass for your guinea pigs to chew on. The only downside is that since it has a bottom, it can get dirty pretty easily depending on the guinea pig. I have a female who pees where she lies, so she'll probably get that tunnel dirty quicker than some of my other guinea pigs. Because it's made from hay, cleaning it with water can lead to mold growth. So keep that in mind if you're looking for something that's easy to clean. Overall I like these tunnels but I expect to have to replace them in a few months.
