Since my vet thinks Jordan may have Asthma, I've been trying to think of all the things that could aggrivate it. One of the things I've wondered about it the litter I'm using. I've been using Worlds Best Cat Litter, however I wonder if the fact that it's corn based could aggrivate his lungs? So I've been trying to figure out if there is a LOW dust litter that is scoopable & works well for a multi cat house hold. Keeping in mind my bug's (Jordan) possbile asthma.
