Alfapet Original Sifting Cat Litter Box Liners - Extra Giant 30 Count - Tear-Resistant Cat Litter Bags - Waterproof Kitty Litter Liners - Fits Almost All Litterbox Pan Sizes, 40" x 38", 30 lb Capacity

I'Ve been using these sifting litter box liners for years. They are the easiest way to clean my cats' litter boxes that I have found. Simply lift the top perforated sheet up and dispose of it leaving the unsoiled litter in the box. I usually top off the box with new litter to eliminate odor. Easy peasy!

I've tried many brands and every style of litter box liners out there—sifting and non-sifting, drawstring and non-drawstring, HDPE and LDPE, .9 mil up to 1.2 mil thickness—and these AlfaPet sifting liners are by far my favorite and I’ve been buying them for years. They're made of high-density polyethylene (HDPE), the crinkly, translucent kind used in grocery and recycling bags; as opposed to low-density polyethylene (LDPE) liners that are white and stretchy, like trash can liners.Everything I've read describes LDPE as having better tear resistance, but I've found that when a cat's claw punctures an LDPE liner, it snags and will either eventually tear it or pull one of the liners up through the dirty litter, allowing litter and waste to seep in between the other sifting layers. But if the cat's claw punctures one of these AlfaPet HDPE liners, it quickly releases, and it’s been my experience that these liners rarely puncture or tear anyway.Some other brands of sifting liners have "hanging chads" that remain in the pre-punched sifting holes, plugging them up and keeping litter and waste from leaking in between the liners underneath; the chads then open and hang down when the liner is lifted allowing the litter to sift through. The holes on these AlfaPet liners are punched clear through, no hanging chads, so I was concerned about litter and waste spreading in between each layered liner. But these liners are well manufactured in a way that each sheet remains tightly attached to the one beneath it, so nothing leaks in between or under the liners.I have three hooded litter boxes: The 21”x16”x5” has a large footprint, but is shallow; the 14”x11”x8” doesn't take up much space but is deep; and the smallest one is 14”x11”x5”. These AlfaPet liners fit perfectly, with just enough overhang on the two largest boxes and substantial overhang on the smallest. LDPE liners are typically made in a rounded bag shape or envelope-shaped with two corners, and both those shapes produce extra pockets of plastic at each end of the litter box where the litter coagulates and clumps up in the plastic, which makes scooping difficult. But these AlfaPet liners are flat sheets of HDPE that when placed in the box and filled with litter, will then fit snugly up against the walls and into the corners of all three sizes of our litter boxes—no more trying to dig clumped litter out of the pockets of plastic in LDPE liners.The only part of these AlfaPet liners that I don’t use is the solid sheet meant to be the bottom layer lining the box—there’s no good way to gather and tie/close it up for disposal. So when setting up the litter boxes, I first line each one with a drawstring LDPE liner, lay five sheets of these AlfaPet sifting liners on top, and then fill with clumping litter. Any more than five sheets and the locks on the hoods won’t snap shut. We scoop daily, then sift once or twice a week. After the last sifting liner is removed, the used litter is gathered up by the bottom drawstring liner and tossed away. Since I don’t use the AlfaPet solid base liners, I have a bunch of them stored away and have found them to come in handy as waterproof drop cloths for crafts—a very useful bonus!

These work just as well as the expensive ones. We change them every other day. They aren’t super thin and flemsy like some other brands.

I’ve bought these sifting litter liners over and over again and won’t use any other liners for my cats’ litter boxes. Being able to sift instead of scoop every time has been very handy and a real time-saver. I have two cats and three litter boxes, so these liners make it easy to keep their boxes clean every day.I use extra-large litter boxes, and the size of these liners is perfect for what I need. They’re also durable. The only time I run into issues is when my cats’ nails get too long and need trimming. Their nails can sometimes catch and tear the liners, but that’s on me for not clipping them sooner.

They worked great initially. Then my cats somehow figured out how to remove the rubber band. I loved everything about it until then LOL

Complete crap! Save your money! These are not cat box liners. It is two sheets of plastic, one with holes in it, and a rubber band, if you’re lucky. Mine was missing.

We have used the Alfapet Sifting Littler Box Liners for 5-6 years & love them! We use the Extra Giant size to go with the box our cats use. They are a great size, very sturdy, easy to use, & free of wierd smells. I discovered that because of the manufacturing process, it can be common for 2 liners to come off at a time if I am not paying attention, which is no big deal. As with plastic vegetable bags, I put the open edge of the liner between the palms of my hands & rub my hands together in circles until the 2 pieces separate. Takes about 2 seconds. Very easy & so worth the cleanliness of the product and its process. They are such an innovative idea and design. I think these are a great value. We have found these liners to be a terrific product. Wouldn't be without them.

We have to change the box every day because of the amount of sticky, urine from our huge senior cat. It's a royal mess. It sticks to the side of the box, coats the scoops so much they have to be soaked and become so big they have to be broken up with a metal putty knife to lift them out.WELL, no more! Now I take the high walled top off, pull the rubber band, lift the corners of the sifting liner, hold it up until the litter sifts out, shake a few times and drop it into a plastic shopping bag.We love our cat but the liter box was draining. Now it takes less than five minutes for what used to take an hour with all the soaking and cleaning. These liners are miraculous. Thank you Alfapet!

Ridiculously large. Too crinkly. Dont really sift well. Wont buy again

I thought this would have been the answer to easy cat litter tray cleaning.As I read in an earlier review, not for a cat with claws. When coming to clean the try, Found big rips in the filter lining. Ended up using the scoop after all.Now Found the perfect cat litter sifting tray on ebay. Much quicker and easier.
