I love my Cat Genie. In fact I love it so much I bought two. But over time I have found that my cats don't all urinate straight down into the bowl. They tend to hit the sides sometimes. And I have found that often their urine finds its way under the sidewalls, under the dome and most unpleasantly, under the processing unit.
I wish they would come up with a better seal or way to block liquid waste from getting under the processing unit.
