I bought this cat tree several months ago for my For "the boys", my 4 boy cats ages 2 to 9 yrs. old.  They all love, love, love, this tree.  After I was able to get it built, all I had to do was rub it down with some cat nip and stand back!  They run up and down it, sleep on it, play on it, and scratch on it.  Great product!  Now the bad news.  It was not packed very well and 3 boards came broken.  Luckily I'm a handy girl and was able to go to Lowe's and buy more MDF and lock nuts, parts etc. seal the MDF, re-carpet new boards, and put the thing together, which I found to be pretty easy.  I know I could have sent it back, either way it was going to be a pain so I chose to rebuild it.  So, My only complaint would be that the product needs to be packaged better for shipping.  Otherwise, I would have given it 5 stars.
