I love my litter box enclosure!  It was exactly what I wanted and It was easy to build since the directions were very clear.  I trained my cat to use it through baby steps and now she has no problem using it whatsoever.  Only one thing we ran into when installing it - the floor is uneven so we had to build a structure attached to the bottom of the enclosure so we could use adjustable metal feet.  We built the structure to also help against warping if someone heavier than intended sat on it.  Kudos to the engineers.  Good quality, looks nice and everything else I mentioned.
