An absolute must have if you own a cat or cats. This is the best investment you can make for your cat and yourself. Very convenient, very easy to clean and best of all is you don’t have to clean every day. Your cat will also thank you for having a clean box after every use. This has payed for itself after 2 years considering it keeps the litter cleaner and you don’t have to buy as much. I have used less then half the litter I used in a regular cat box or even the GARBAGE rake units they sell. I have owed for three years and there is no way Blue (my cat) or I could live without it. Thank you litter robot and the people behind it. P.S. don’t think about it, just get it. You will be so happy.
