Never seen one of these before (litter tray)

I'll stick with my hooded tray and Cats Best, no odours in my house most of the time.

that's the thing isn't it, if you scoop it regularly it shouldn't smell

For a start, it doesn't look very big, Dave certainly wouldn't get more than a back leg in there! What about the noise it makes? Would probably take a long time for  some cats to even go near the thing let alone anything else.

As for the odour extraction, what about the odour that will escape through the blinking big doorless entrance

I dont think anything could make what comes out of a cats bum more "rosey"

Bit pricey (well, a lot pricey!) but an interesting idea.  Wonder if it works.
