I absolutely love PrettyLitter! There is little to no smell all month, much less tracking, it's lightweight, and when it does track you don't see it as easily. I find it way easier to scoop than clay litter and way easier to clean out the box every month. My cat has no problems with it, and I love being able to check up on how he's doing by the color in the box.
I currently get two bags a month, so I can change it a little more often to see if it helps my allergies (yes, I'm allergic to cats, but I love pets too much to not have any!), but one bag a month was absolutely fine for my one cat. The last day or so I would start to notice a smell by the box, and I was always delighted to find that by that point my new bag was already in the mail! I would absolutely recommend this to others; it makes having a cat just that much more pleasant!
Bottom Line: Yes, I would recommend this to a friend
