The Scoop Free Self Cleaning Litter Box is amazing! It controls odors, the box is always clean, and my cat loves it as much as I do. It is easy to set up and wipe clean when switching the litter. I have 1 cat so my l tray last about 30 days. It is easy to pull out the raked solids if you don’t like the idea of it being in the closed off section for too long.
