this is the best liter box ever !  It looks like a piece of furniture but neatly hides the litter box inside. And there is room to add a mat where they walk in and out which collects the liter off their feet. My husband thought I was a little looney when I bought it, but now he sees how great it is too !  And the cats - well they went right in as soon as it was put together ! No litter box to look at, no smell because they are inside and it looks great in the room .
