Timely arrival, well made and everything fit.  Took a few hours to assemble because I added 3/8 in insulation to the walls.
The 4 star rating instead of 5 is due to the rigid swinging door.  Doors like that are potentially lethal. The cat can only go all the way, it cannot back up. If something frightens it, it could kill itself trying to get away.  The manufacturer should change it to a vinyl flap like the other doors.  I propped ours open with eye bolts and wire.
