I have a cat. We use Tidy Cat Small Spaces, similar to what the cat's previous owner used. It does good with odor control. I'm not sure it causes dust or not because I dont deal with the litter, my DH does that. I have heard Feline Pine is good. I want to eventually change my cat over to it. It has no chemicals, recycled material, no harsh fragrances, lightweight to tote, no silica dust - go to www.felinepine.com. I know you can purchase it in Wal-Mart, I've seen it in the Super Centers. It cost about the same as other cat litters.
