The box is spacious and comfortable for the owner for cleaning die to the pull-out-drawer.
Unfortunately I missed in the description an important detail: once the cat is inside the box, she can get out only by the lid in the roof of the toilet. At the front door are on bother sides small pins which makes it impossible to get out on same way as they got in. Because not all cats are so smart and know from 1st second how to use it, they can come quickly into distress and panic because they feel trapped! My cats are all previous streetcars, they are used to open toilet bowls or closed toilets where I removed the front door. To reduce this distress I will remove now the pins at the front door so they can go in and out as they want!
I gave only 3 * because of the missing information in the description and that is is designed like a trap; very inconvenient for cats who are not used to closed cat toilets at all!
