Alfapet Original Sifting Cat Litter Box Liners - Extra Giant 60 Count - Tear-Resistant Cat Litter Bags - Waterproof Kitty Litter Liners - Fits Almost All Litterbox Pan Sizes, 40" x 38", 30 lb Capacity

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.

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!

After being a loyal customer of the shifting box liners for over half a decade, I am finished with them. These liners revolutionized cat box cleaning as, I believe, they were the first company to introduce liners with holes that permitted dry litter to fall into the next layer. The solid waste and wet litter was trapped in the top liner and thrown away. No dirty litter box scoop necessary. I became an habitual user of Alfapet Kitty Cat Liners for my two Siamese that use the same box, eat out of the same food bowls and sleep together during their numerous "naps" daily. (They're litter mates, if your wondering how that could be)!After several years, I noticed one of the "boyz" was pulling up the current liner while covering his business. This led to the problem of wet sand seeping down to the next layer, and when pulling the dirty liner out, it stuck to the next one because of the moisture seeping down. This question has been asked in the "Customer Question" section, with unsatisfactory answers. This problem just started a year or so ago for me, personally.I tried tightening the layers by using several of the used rubber bands (one of which is included in each box). Also tried cutting excess corners of plastic after placing the liners in the plastic pan. It has been an ongoing problem, so I decided to try to contact the Alfapet website for help.That has been biggest waste of time as I tried, unsuccessfully, to reach the customer service several times as telephone number and extension listed was never answered. A recording said to leave message and a representative would get back to you. After never hearing back for the phone number, I tried leaving emails, which were completely ignored as well.I can now tell you after complete disregard for their customers, I have stumbled on another brand of shifting box lines that are even better than Alfapet's Kitty Cat. VanNess makes the same liners in a much thicker grade of plastic sheet that is easier to lay down and place in the litter pan.Also included is a much thicker rubber band that snuggly attaches around the box. Remember, I said that I started using three and four of the thin, limp bands on the Kitty Cat brand to accomplish the same thing.In conclusion, the VanNess brand is a much better product now than that of the Alfapet Kitty Cat shifting liners. So far, the weight of the plastic sheets is controlling the problem of wet underneath liners. I just thank Alfapet for completely ignoring my plea for information. They turned me on to VanNess!

I don’t know why it has taken over 60 years for me to discover sifting catbox liners, but thank God I did! It is so much easier to clean the catbox this way, especially since I’m older now and it’s harder to bend over to scoop. Instead, you just lift up the liner on top, and the sand sifts through the liner holes until there is only the “stuff” that you wanted to scoop! It’s lighter to pick up and dispose of it, and feels cleaner since you don’t have to pick up the “stuff” yourself!Also, this is a package of 10, so it lasts longer and is more cost-effective. The ones at my grocery store only come in a box of 7 liners, and it costs over 7 dollars!

Ordered large was shipped Gigantic. Had to remove excess. Size never accurate on these orders for litter liners.
