This box is a really great way to hide a litter box that is also decorative and funtional as a seat or place for a plant.  I only gave it four stars because if it was a little bit taller and longer, it would be perfect for large cats.  My cat is a large framed and has been using it but it's a little cramped.  Because my cat is large, I left out the inner pathway door so some litter does escape but it's miles better that just a plain litter box with lid. I can't say it perfectily hides the smell but again, much better than a plain litter box with lid.  I would recommend this product.  A very basic large sized pan fits perfectly if you put in the inner door and I recommend some kind of matting to prevent the pan from sliding and catching litter if you leave out the inner door.
