Litter robot is pretty good. I have 3 of them, and while the new ones look nicer, my older ones work better imo. You have to use a good brand of clumping litter, or it won’t work at all.
There is also Cat genie, which requires a waterline, and it uses reusable little balls instead of litter. After your cat goes to the bathroom, it self cleans the balls and flushes out the poo and pee, and then it dries itself with hot air. I would love to get one of these but they are fairly big and I just don’t have the space for it.
What’s sockpuppeting?
