I wouldn't mind using A+H if it clumped better. A+H (Multicat) does not clump well at all. When it breaks, I found that to add to the smell. A+H isn't dusty though.
I use Scoop Away. They are more dusty, but if I put the litter into the box gently, it helps deep the dust down. They clump REALLY well and keeps the smell down too. With 3 cats, I clean the litterbox at least once a day... sometimes twice.
