I've never used litter, always newspaper (free), with a layer of paper towel on top to keep the newsprint off their feet and to keep them from slipping when spreading their legs. Yes, clean up is much easier than with litter, which I did use long ago, and the cost of paper towel + free newspaper is cheaper than the cost of litter. I use only the 'white' sections of newspaper, never the color ads.
