Even my tunnel came in the color blue / turquoise on gestreitft. As several customers complained about this already, it does not seem to enter the tunnel in Brown. The color is not beautiful, therefore, the tunnel is not now in the living room, where he was supposed to go. The seller should perhaps specify times that it is color-sorted tunnel. Furthermore, the but for my cat - normal size - a bit short. So just for small cats / tomcat.
