I recently switched to Arm & Hammer. I use either the Multi-cat or Super Scoop (I think that's what it's called!). The cats seem to like it better---I sure do. The cost over Walmart's brand is almost double, but I don't have to change it as often. With 12 boxes, it gets to be both time consuming and expensive. I did notice that there was quite a bit of dust when I pour it into the litter box. It clumps well and smells good for a long time, up to 2 weeks with twice-a-day scooping.

Only Joey has accidents now, and that's a whole different issue!
