Cats don't generally like "scented" litters, and I think they were made for the owners so they don't have to smell the odor of a litterbox. My RB cat Mollie Rose had severe kitty allergies and asthma. That's why I switched to Feline Pine pellets. Absorbs the urine odor and you only have to remove the solid waste daily. Once the pellets breaks down to sawdust, you dump the box and start over. It's great. No silica dust, very little tracking.
