It turns out my cat has some kind of allergy to his litter (WBCL) so I need to switch back to a clay based litter. I've also used Feline Pine (he wouldn't even touch it), Swheat Scoop (it sticks too the bottom) and Fresh Step crystals so I'm limited to the store-brand clay litters. Has anyone used Cat's Pride? If so, how was the tracking, dust factor, and odor control?
