Review on Alfapet Kitty Cat Pan Disposable Elastic Liners- 10-Pack 🐱 for Large Litter Boxes with Sta-Put Technology and Quick Waste Cleaners by Anna Crane

This is my choice. Fits in my giant cat's giant crate while XL sized bags do not. I can't go back to anything other than those giant elastic rims holding them in place. The only reason they don't have 5 stars is because when I change them there is usually a lot of moisture at the bottom of the tray - no obvious leaks or anything, it's probably just pin pricks. I've never used a cat box liner where it's NOT VALID, but it leaves a little room for improvement. In general, they are very durable.
