We’ve been using this for a little bit of time now. My one finicky feline is still getting used to it. My little one has adapted. I work two jobs so changing litter isn’t always on my list of things to do and by time I would get to it it would be bad. I would try to make myself remember but that would be hard with working so much. This little gadget is coming in handy so far. It’s working good so far. No complaints yet.
