Purina Tidy Cats Clumping Cat Litter, 24/7 Performance Multi Cat Litter - 35 lb. Pail

Is this litter really dust free? My cat isn't allergic but I'm allergic to dust...and the crystal litters are kinda pricey.

I'm confused, did something change with this litter? it does not clump anymore.

Has anyone's hairy baby had adverse affects with this litter like those I have heard about the Light Weight formula?

Is this a scented litter?
