Very good litter box, with good quality plastics. It also has a scoop that you hang outside. The super convenient feature is in daily cleaning where the roof opens completely, and the top part can be completely removed for changing all the sand and washing. Also, at the front, there is a small sieve inside that somewhat limits the sand from coming out. The door is like in all litter boxes. The only downside is that it is relatively small in size, and while my smaller cat uses it comfortably, my larger cat, who is a bit chubby, doesn't fit in it at all. If it were available in a larger size, I would buy it again.
