These littler box liners are an extra large size, which is great, and they are heavier, than other liners, I have tried. I have two cats and the liners hold up, through their scratching, as they try to cover their "deposits". Even though their claws may tear at it, the liners still hold up and can be easily removed, to replace. I only wish the box contained more liners, there are only seven. It would be nice, if they had at least ten, in a box! Other than that, I am happy with the product and will continue to purchase these liners.
