    • 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.

    Box liners

    I do find the liners fine to use, but think you should tape the seams on the inside. You tape the outside, but not the inside.
    I can't be the only user who finds the cat urinates on the seam which results pee behind the flap as well as the stings/threading breaking down due to scratching and urine.

    Love these liners. I love that I can replace them. They are heavy-duty as well. You can take them out and wash them off. They last forever, but I like replacing them periodically for sanitary reasons. They protect the litter box very well. Genius.
