We purchased this kitty condo because we had to put a litter box in an upstair bedroom closet.   We were afraid of the mess and dust flying around.  This seems to be working exactly as we expected.  It is easy to clean and open and my kittie goes in it with no problems.  There is plenty of room for an extra large litter pan.  The litter gets in the cracks along the sides, but is easily vacuumed out with a crevice tool.  Since the front door open, the top is left available to use as additional "table top" space for anything.    It was easy to put together and has seem to last with no problems.
