PLeasantly surprised. I did not realize this was cardboard.  or I might not have bought it.  My cats tear up cardboard scratchers in no time.... $ 20 down the drain and alot of mess on my floors.  
    So far, they love it and the cardboard does not seem to be falling apart. 
  It was a 7 out of 10 easy to put together, not totally, but I am NOT handy with putting stuff together and even I did it. 
   I liked the insert where the head guy gave his personal cell phone if there were issues.  I did not call him. 
  It is a great idea to find more uses for recycled card board also.  I am looking forward to how this "wears".
