OMG I have to tell everyone that this is fantastic.
I have adult cats and a litter tray so big that I usually feel like I am mucking out a barn. This scoop is amazing, it must have cut down the time it takes to clean my cats best clumping litter down to about 20% of normal. It's really big, so one scoop gets more litter. It has nice deep sides so that less falls off in shaking. It has perfectly sized holes so less shaking is necessary because most of the clean stuff falls through anyway, the clumps are less disturbed, no dirty bits end up back in
