I have been using the traditional litter box with scoop for my indoor/outdoor cat. Don’t mind scooping the box but cleaning the litter from the floor and anything that is near it is a pain. It took “Max” a few days to adapt to the new box and litter. A little bit still gets on the floor but so much better. It is a bonus bit to have to clean it. I will, however, buy a refillable tray to make refilling it more affordable.
