discovered this idea online: put the paper from your paper shredder in the kitty box. Have been trying it out and my kitty doesn't mind at all. He does track paper shreds, but then again he also tracked sand previously, so the vacuum stays in commission regardless. The people online were paranoid about ink from the paper rubbing off on kitty's paws but I don't see that happening, nor paw irritations, so I don't wash and dry my paper shreds first, like the online folks suggest. Tell you what, we are saving money on litter and also reducing our dependance on clay mining.
