I have been using PrettyLitter for a couple of years now and I wouldn't use anything else. I have four cats, and only one large litter box. PrettyLitter absorbs odor well, is lightweight, easy to use, and with four cats, one 6 lbs bag lasts a week (with proper cleaning).
I have tried other brands and they just don't live up to PrettyLitter's performance, worry-free delivery, and customer service.
The folks at PrettyLitter are obviously pet parents and are very understanding, responsive, and helpful when needed.
If you're on the fence, PrettyLitter is worth it!
Bottom Line: Yes, I would recommend this to a friend
