My nizmo kitty is a very peculiar kitty. He demands his litter box to be clean for him. He will not use it unless its cleaned. Finicky little cat! So needless to say it was a great idea for me to purchase a self scooping litter box. Well let me tell you, the pet safe self cleaning litter box is,in my opinion, the best littler box money can buy. I have a happy kitty every day. I simply clean the little tray. It saves me so much time. Thank you so much for this one
