“First off, I will say that we are really happy having switched to Kitty Poo Club/silica litter. It's so much easier to clean, there is *significantly* less waste, and just feels a lot more hygienic. We transitioned our cat over a monthlong period and he did just fine. The only cons that I've noticed is that the silica doesn't do as great a job at odor control for #2 as a clay/clumping litter might. Also, the silica does track here and there, which wouldn't be such a big deal if my cat didn't love to play with the silica beads and kick them around the house, and also try to eat them once he's "caught" them! But that might just be my crazy feline ;-) we vacuum regularly to prevent any harmful ingestion and thus far are really happy with the service.”
