I wanted to love this this kitty litter because it is so eco friendly. It did an excellent job with odor and my cats had no issues with it. My only problem is that the litter is so light weight that it stick in my cats fur and it also seems to get tracked everywhere (more so than other litters I have tried). Not the worst thing in the world, but it was bothersome enough that I just don't think I can keep using Catalyst.
