    Vastly superior to plastic grocery store bags, though those are handy in a pinch. These liners are steady and nearly rip-proof.

    Great heery duty liner bags

    I am impressed with this purchase. Strongly made liners with the flaps easily used in keeper.

    Litter Keeper Liners -Type H

    Fits perfectly, durable and strong. I don’t worry when removing and discarding that there’s going to be any holes or slits in the bags.

    This is a smart system. Easy to hook the handle into the litter container. Does not fall down. So far the bags seem sturdy. No ripping with heavy loads. In addition to scooping clumps, I can add the old litter when changing the box. Easy peasy.


    Repeat purchase. I re-use plastic grocery store bags when I have them, but these are so much more durable. They also contain odor better.
