Soooooo awesome.  Went together easily.  My cats actually use it.  No question.  I feed them on the top landing (under roof) to keep the food out of reach from the dog.  Perfect for what I needed.  I did add some extra pieces to make a lower landing back/side to put another bed.  the very bottom area is way too small for actual cats (9 lbs) to access or feel comfortable using.  So, it's just a raised floor.  Love it.
