Personally I use the clumping litter (think the brand I have now is Fresh Step.) I know many people who dislike it because it is not naturalistic, etc. But I use it because I don't have much time to clean the box; if it goes 2 days or so and i don't get to it every day, I never notice any odors from it. It makes things very tidy It is not that dusty; it is when you first pour it in, but after that I never have issues with it; and my boyfriend sneezes at every little thing, but not this.
