I was worried that this might be a bit flimsy after reading reviews on cat tunnels, but it is actually very sturdy and has really kept our young cat busy. It makes crinkle sounds which he loves. He jumps on it, dives through it, rolls around in it and it doesn't show any sign of wear after almost 2 months of thoroughly being used. It is a decent enough length. There are more expensive ones out there, but I think this is a good one to first see if you cat will like a tunnel.
