luv the finished product except it wobbles a little but the cats dont seem to mind.  labeling all the pieces beforehand and grouping like pieces together in the correct order is a must.  the piece must be EXACT in every way  to the picture in the diagram so pay close attention to the details and take your time laying everything out and labeling everything correctly.you dont want to get half way through assembly and have to back track its to big of a project.  when its all put together your cats will luv it
