I put off this purchase for a while, thinking it was silly to spend money on cardboard and I should just build my own maze for free with the boxes I have sitting around. But of course I never got around to doing that, so eventually I gave in and bought this. I’m glad I did- it’s well designed, it was easy to put together, the cardboard is sturdy, it shipped quickly, and my mini rexes love it. They aren’t destroying it as quickly as I feared they would. I think it will last 5-6 months with the rabbits using it about 6 hours a day. It helps that they are litter trained and they aren’t huge cardboard chewers.
