I think the dark taupe is very forgiving. In other reviews, the white seems opposite for people, which is why I changed my mind. My cats have all investigated it, then used it. My 14lb male has seemingly used it and hes the biggest that I have.   Its great for underneath the stair rise, but might be too short in a regular room. I put it together in under an hour.  There were a few moments that were difficult, alone, as a petite. Only, because of lack of arm length when connecting the pieces. Regardless, grab your drill. It will be easier. Unless your kitties love to lay in your way on all the pieces.
