I have used cat litter we buy at Sams Club and I am telling u it is the best ever, ever. It is about $9 for 40 lbs. and it has a nice smell, very little but boy does it work. U have to at least try it if u have a Sams Club near you. It is the only place I have ever seen it and only one they carry. WalMart does not even carry it, just Sams Club. It comes in a bucket and is called LitterClean, all neutual and triple odor......it works so great, u do not even smell it except when u put it in the box. I am telling u, if it does not work and u like it, I will give u the money back.....that is how I know it is so great.......u must find it and all of u on here........unbelievable.
