I use all different types, but in different boxes. I like it because it is light, light, light and easy to scoop. It is all natural. I will have to admit it takes some getting used to the smell. Its not awful, its just icky, not pleasant. My cats prefer the standard food store brand, but I make them use whatever kind I have at the time. They prefer the cheap stuff, dusty stuff. Oh well.

I also have lids on most of the cat boxes which keeps the odor confined a bit. I do the "kitty litter patrol" thing once a day. I have a couple of boxes on the outside porch, so that eases the nasty odors somewhat in the winter.

On a scale of 1 to 10, I would give the World's Best about a 7.

I don't use the litter - so maybe you should be asking my cats!
