Can anyone recommend a good dust free cat litter? My cat currently has one from Morrison’s that’s similar texture to Catsan. The granule type. It’s non clumping. She doesn’t like wood pellet ones. Anyway, she has chronic cat flu so sneezes a lot and I find it’s quite dusty which surely doesn’t help! She generally only uses the litter tray for a wee, and goes outside for number 2. Any good ones out there that are less dusty?
