I have a very small space to work with (hence why the guitar is on top) and this was a little bit larger than expected however I do love it and so does my cat.  I took off a star because the doors do not align which bothers me to no end and also because although the side ends are reversible allowing the cat to enter from either left or right, you cannot have the partition be either right or left..... and that is frustrating.  Either the cat walks through the smaller area to get to the litter box, or they have a little room behind the box which doesn’t make sense.  All that would need to be done to rectify this situation would be to add the holes to the other side as well so it could truly go one way or the other.  Otherwise, very easy to assemble and looks great!  I’m happy with this purchase.  Took the advice of another reviewer and added a motion sensor light inside.... nice touch )
