I had a Kidney transplant several years ago and I am supposed to stay away from cat feces. My husband was gracious enough to handle the old litter box for us but he HATED IT!! We were tired of our house smelling like cat poo...you know how that is...ewe!! Now, All we do is hit a button and the clean up process begins.. I LOVE TO HIT THAT BUTTON!! Easy set up..my 19 yr old son set this up in 30 minutes..tops! Best purchase of the year! We have had ours for 6 months.
