I was a little worried about my two cats adjusting to the catgenie because they are older, but they had no problems with it. They accepted and took right to it. The granules do get everywhere, but no more than the regular cat litter did. Also, you can't tell that there are cats in the house because the smell of the litter box is gone which was my main objective in buying the catgenie. I would highly recommend the catgenie.
