I mix tidy and good mews it smells good and is really apsobant. (sp) Good mews is a recyclesd paper and cedar oil, but itds larger and cats not crazy about it so I layer it on bottom and then but Tidy cat on top. Now we are all happy except Winky who MUST go out side or he uses bathtub if he can't hold it any longer. Easy to clean but not my choice for him.
