Anyone on here use a self-cleaning/scooping/washing litter box? I had a "Litter Free" self washing box 20 years ago. Worked fine for a year til it clogged and I had to remove it in a hurry but when I was able to clean it out and set it back up it wouldn't work at all so it was trashed. I don't want the Cat Genie that's out now although I have the plumbing in place for it left from the previous one. I'm considering one of the SmartScoop electronic boxes. I'm tired of scooping and Tony isn't able to squat down anymore due to his leg issue. I used to have a cat that could use the toilet and I believe my Samson could do it but his two sisters not so much.
