Review on 🐱 Alfapet Kitty Cat Pan Disposable, Elastic Sifting Liners - 5-Pack + 1 Solid Transfer Liner - for Large, X-Large, Giant, Extra-Giant Size Litter Boxes - Easy Fit Sta-Put Technology - Pack of 2: An Efficient Solution for Effortless Litter Box Maintenance by Michelle Bonner

I have used other strainer cup inserts and had trouble setting them up for use! First you had to get a square insert to fit the oval pan, and then along came these rubber bands. Yes it was fun. However, they are easy to enter. They fit my pan shape very easily (and my sister; I buy them for her too. Square shape) very easily and I don't feel like I'm filling out the bottom layers due to the poor fit. Because of this, I haven't had to clean my physical box for years! My box stays clean and I just throw away the bottom layer and put in a new wrapper! *** I have to clean the lid/top from time to time, but it's easy.
