I love love love it. I used to use the LitterMaid but I found that it seemed to be manufactured more flimsily over the years. When my cat got older (she lived past 21), she drank lots of water and made very large pee clumps. The LitterMaid could not handle the weight of these clumps. I feel confident that LitterRobot will continue to work where LitterMaid failed. It is a much better design.
