Easy, clean and ready to use! All I can say is WOW! I'm saving money..time and my house dosent smell like a giant cat box! I really love the fact I don't have to dal at all with the waste. All I do is remove the box..cover it up with the included lid and dispose of it! It's that simple! And depending on the number of cats that are in your family the handy 3 pack will last you months!
