I use clay litter because I'm not real good about scooping everyday. I just clean out the litter box completely weekly. The Petco litter is pretty good and I like the fact that you can refill the reusable plastic bucket. It goes on sale so often and this makes it really cost effective. Plus, our Petco is close enough that it's not a problem to get in there when I need stuff.

Pros: good clay litter--cost effective, can refill container

Cons: none

I prefer the Petco litter to many other brands, however, I don't always have time to go out of my way to Petco, so I end up buying other brands at the grocery store or Sam's Club.

Pros: High Quality

Cons: Availability
