We reviewed the Litter-Robot 3 after using it for many years and reviewed the upgraded Litter-Robot 4 as soon as we could get it in our hands after testing many other brands of automatic litter boxes in the past. We’ve been proud cat parents of an adopted fur baby for about four years now and are no strangers to scooping cat litter.
