I researched and looked at several litterbox enclosures and finally chose this one. It's longer than most of the enclosures  I saw on line and fit a larger/longer oval shaped litterbox perfectly. I did line the inside with contact paper just in case there was any spillage or accidents that didn't make it into the litterbox. I also put a very small litterbox at the cat entrance so it would collect any litter before stepping out, it has worked perfectly. We put the box together which was easy and quick according to my husband and left it out and left the doors open do the cats could investigate and get use to it before placing the litterbox in it. We then out it in the designated spot and left one side of the doors open do the cats could see the box fir a coue days then closed it. The cats adjusted well and we are very happy with this product. Looks like a nice peace of furniture. Would purchase another if needed.
