Flip Paperboard Liners (6-Pack)

Flip Paperboard Liners are a disposable alternative to the Flip Tarp Liners. They are constructed of a single, seamless, coated sheet of recycled paperboard. The Flip Paperboard Liners are liquid tight, scratch-resistant and can last up to a month. Simply unfold a liner, drop inside the Flip Litter Box and secure with the liner band. When things get too messy just fold it up and throw it out!

Dimensions: 17L x 12.75W x 9H in (43L x 32W x 23H cm)

* This product requires the Flip Paperboard Liner Band for use (sold separately).

NOTE: A clean litter box makes for a healthy and happy cat. We recommend replacing Flip Paperboard Liners when there are signs of wear and tear to keep bacteria and odor in check. The longevity of the liners depends on how much litter is used, how many cats use the litter box, and how ferociously they scratch. Daily scooping and sustaining the litter level at 2-3 inches (5-7.5 cm) will maximize the life of the liners.

Flip paperboard liners are great!

Love these liners! So easy to use. Kitty bob loves her flip top cat box.
It’s super easy to clean too!

Paperboard Liner

The paperboard liner works so much better than the silver plastic liner. The clumping Crystal litter I use barely sticks to it and lasts so much longer between changes. The only issue I have is the plastic holder so I prefer to tape it to the Modkat box.

Makes changing the litter a breeze!

These are well made and are working out really well for me! They are less expensive than the other liners, work just as well, and although I know nothing really decomposes in landfills, they feel more environment-friendly. When it's time to change the litter, I take the cardboard liner out and throw everything out! Easy breezy. I can even change the littler it my tiny apartment kitchen without making a mess. Thanks ModKat!


5 star


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!
