Fresh Step is by far the best....scoopable. I never actually empty the litter box, just keep it scooped and add to it to keep it at a decent level. I use no additives or anything else. We have 2 litter boxes and 6 cats and absolutely NO SMELL. glenda
Also a tip for others.....I use a 4" taping knife ( for taping sheetrock seams) and scrape the bottom and sides before I scoop.
