I've tried most of the different types of litter over the years, not all brands of each, it is true, but most of the different types available.
I can tell you that clumping is my choice and Arm and Hammer seems to be one of the best I've tried. It clumps well, is reasonably easy to scoop and doesn't stick too much (although you will find some sticking), Main thing is that it is great for odour control.
Biggest downfall? Very heavy! Clumping litter is always heavy to transport and heavy to take out to the trash!
