The Forever Litter Cartridge features a floating tray that lifts so that the kitty’s "gifts" can be swept under, then comes down to further trap odors. Of course, like the rest of the tray, it can be wiped clean if necessary.

We found this sign in a lift in a friends compound. Sorry about the poor quality of the photo, it is a still from a video tape, with the lighting (or lack thereof) and the shininess of the sign it was almost impossible to get a decent photo. At first I just did not believe they actually wrote that last rule like that. Have a look a the notes to see what we noticed. I like how they grouped people together in point 8.3.
This is a most effective expectorant!
I like the idea that a psychopath must be accompanied. I suppose it gives them someone to kill and dismember on the way down….
