The enclosure was very easy to put together and the size perfect.  My 4 cats used it immediately without any issue.  I did leave the "door" open for the first day to they could see what was going on..then closed it.  Everyone knew what to do. Since I've had to move the litter box upstairs in plain view of all to see, this product really fit the bill and took care of an unsightly problem.  The only issue is I have to sweep the floor all the time but that is not a "product fault".
My only disappointment is that the colors to choose from are only white and walnut, neither of which fit with the surrounding decor, I got the walnut and it is very dark, so I dressed it up with a table runner and fake flowers.
The price was right for a "test".  The test worked
