    • A clean litter box makes for a healthy and happy cat. We recommend replacing Modkat Reusable Liners when there are signs of fraying, or after 3 months use to keep bacteria and odor in check. The integrity of the liners depends on how many cats use the litter box, how much litter is used, and how ferociously they scratch. Daily scooping and sustaining the litter level at 2-3 inches (5-7.5 cm) will maximize their life.

    I’ve been using this for years. So glad they are back in stock!


    Great liners. They are durable and last. Also makes it easy to clean when I have to do a full litter change out.


    My cat always scratches at the sides of her box and the liners after she has used her box. These are the only liners which hold up! And they make cleaning up so easy!


    Would be a better product with one additional grommet on either side to prevent sagging, but overall a sturdy and reliable liner

    Excellent product, does what it is supposed to do!

    I love my modkat litter box so much and I do love the liners too! I take every chance I can to show my cat friends my beautiful “modern” litter box. I have the Flip Litter box which has high sides, perfect for my cat that apparently enjoys spraying as high as she can. I like that these liners last 3 months at a time, and I find they help a little with dust from the cat litter itself. The only concern I have for the liners is the fact that they aren’t eco-friendly. I wish there was a high sided cardboard one to fit on the inside, or one that is biodegradable within a reasonable amount of time. I wait patiently hoping that modkat comes out with one. :)
