Review on Hyper Cat Litter Liners Drawstring Cats by Carolina Hefa

They keep what they promise. They are LARGE and easily fit in my 17" x 21" cat box. Very heavy, so cats can poke a few holes in it with their claws, but they can't tear it. Those are the only cat insoles I could ever say that about. I always put newspaper between the box and the liner to catch any cat leaks I always have, but the original newspaper stays dry after eight liner changes. A tip on how to tell if they will fit your large tray is to add measurements from one side and the front of the tray. This is the width of the product you need.
