Pricey but worth it!
I've used all kinds of litter, but have been using crystals for about two years now. I can't always get Fresh Step crystals, so I often buy store brands, etc., but really, there is nothing like this one. The kitty is very very comfortable with it; it doesn't stick to her and end up all over the house; there is never any smell (although I clean it out every day); and it lasts for a long long time, at least a month for our one cat.
I'd love to get a break on the shipping, though. That's a killer!
ProsNo smell; no mess; no sticking to kitty; comfort for the cat; easy to work with.
