The paperboard liners are great. One of my cats is a real digger and she scratched up the reusable liners so much that the urine would seep into the fibers they would retain the odor no matter what I tried to clean them with. The same cat also scratches holes in the paperboard liners. (I only got 4 weeks out of the first one.) If Modkat could make these with a reinforced bottom that resists scratching, they'd be perfect. But they are otherwise pretty sturdy and don't retain any odor. And they make changing the litter much easier and less time consuming!
I am very happy with the flip paperboard liners. They make dealing with cat litter not quite as 'dirty' as I'm able to throw everything away. Love them!
I am using my first one and so far I am impressed. They do seem to be a little costly!
I really like the Flip Litter Box they are used in.
