Yep, I am still at it. My two cats are, umm, eagerly using the Litter Kwitter most of the time but not all. They urinate 100 percent of the time but litter in it about 50 percent of the time. In the evenings they use the drain next to the toilet but during the day, use the toilet. I am beginning to wonder if it has to do with lack of lighting at night.
They are up to the green tray not but I think they will be there for a couple of weeks.
(Litter Kwitter Orange Tray was a success)
