I wish I had tried this years ago. I have 3 indoor cats, so I clean the litterboxes several times a day. This new scoop free self cleaning litterbox is amazing. It's quick to set up, plug it in and it's ready to go. About ten minutes after the cat uses the litter box, the metal take slowly runs across the crystals, scooping the waste as it goes. The end of the tray slowly opens and the used litter and waste that has just been combed, deposits into the end. The scoop slowly goes back as the cover slowly settles back into place. Clean litterbox! It actually works that easy. This is amazing how efficiently it works and keeps it clean and fresh. This is something that cat owners need. Great product!
