I'm so happy not to have to scoop cat waste I like the unique crystals instead of litter with having 2 cats it seemed like a never ending job now I only have to empty the reserve tank ! Less mess ! The crystals are a little pricey but once you realize you aren't buying litter every week or month you actually save money ! No litter to clean up after they use the box either ! It does take a few days for them to take to it but after that it's smooth sailing ! #IGotItFree  #tryitsampling
