I am SO tired of the traditional cat trees that attract fur.  Even though we have several of them, it is impossible to keep them looking nice when we have 8 cats using them.  I think these bare wood ones will stay looking much nicer.  I just put it together and it was very easy, in spite of my feline helpers >^.^<  I also like the option that you can paint or stain them to match the decor of the room you are using them in.
