Aww how cute. I have 4 buns and I have been thinking about getting them a tunnel like that.
I posted a thread with pictures of my buns. I have a cat tunnel that my cats don't use I think it will now become a rabbit tunnel lol. My buns love cardboard boxes so they always have one of them and a bunny maze like the one below.aw you should post pics! mine love tunnels I have them a big cat one too but it doesn't fit in their exercise run thing it takes up all the space so i wanted a smaller one..
