I’ve tried all types of litter and had been using a very popular,  brand for years, but have been disappointed by the large amount of dust.  I decided to try Dr. Elsey’s as it is advertised as 99.9% dust-free.  I only switched the litter in one of the litter boxes and was surprised to find that all of my cats “voted” by going in that one litter box.  The litter clumps great and appears to be much less dusty than the brand I had been using.  I am extremely thrilled with it, but more importantly, my cats love it. If you haven’t tried Precious Cat Ultra Premium Clumping Cat Litter you need to. You owe it to yourself and your cat(s)!
