Cat will actually use this one...
This has very fine grains which are the preference of our picky cat, so he seems to like this one, versus others we where he wouldn't even put his feet on the surface. From our perspective as tray-cleaning slaves, the litter forms very firm clumps almost instantly, which are easy to lift from the remaining litter, so this works out very economically in the long run and is easier to keep clean for longer than other types. Only lightly scented, so doesn't deter the cat from using. Will buy more!
