    • 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.

    Type F liners

    THE BEST !! My second purchase. Lasts me a whole year , just one liner. Every 3 I wash it out and refill with litter. So muncher easier ! I do sprinkle regular baking soda at the edges. LOVE ❤️ it!


    These things are worth their weight in gold - 5 stars isn’t enough.
    It has made cleaning the litter box a breeze & the box itself still looks as good now as it did when I purchased it well over a year ago.
    They last a good long while as well. I don’t remember the recommendation for how often to change them, but I’ve found for our cats, I usually change the liner every 4th full litter dump/new bag.

    These are better than the paper liners.

    I like these liners, but I hate cleaning them. I’ve used these liners for a years now. I had recently purchased the paper liners for ease of cleaning. But they are absolute total garbage, and I regret purchasing those. I followed all of the instructions, and they don’t even last two days! It was a complete and total waste of money. I should’ve just purchased more of the reusable liners to begin with instead of being out a whole bunch of money for something that I can’t even use. Be warned if you purchase the paper liners and you have a high peeing cat you will be sorry and also if you have a cat that digs in there let box, you will be sorry. Reusable liners, five stars paper liners -1,000,000 stars!!!


    I love that they last a while and are very easy to clean. I don’t like how they seem to be the product that is most often sold out.
