Cat Litter Box Liners, 17.7 x 17.7 Inches

When it’s time to empty an automatic litter box, a liner that closes quickly can make the mess easier to carry out. These 17.7 x 17.7-inch cat litter box bags have drawstrings for sealing used litter before disposal.

The pack includes four rolls with 20 bags per roll, for 80 bags total. They’re intended for compatible automatic litter boxes, not as a universal fit for every waste bin.

If you prioritize quick, contained cleanup, the drawstring design is useful, if you prefer a liner matched to a specific box model, confirm the fit before choosing these.

Getting the most from it

Start with the waste compartment, not the bag count. The listing says these liners are designed for compatible Ducksky automatic litter box models and fit smart litter box bins with length plus width of 16 inches or less. Each bag measures 17.7 x 17.7 inches, but that alone doesn’t confirm how it will sit in a particular compartment. Check the bin dimensions and model details before buying, without that measurement, fit is uncertain.

In everyday use, the drawstring gives you a way to gather the bag’s opening after removing it from the waste drawer. For example, when the drawer is full, you can pull the cord closed before carrying the liner to the trash, rather than handling an open bag of used litter. That’s a practical convenience, though the listing doesn’t provide details about the drawstring’s construction or bag thickness.

Why it’s worth it

Four rolls mean you can keep replacements nearby instead of reaching for a new box after only a few changes. The product states that each bag holds 18–22 pounds of litter, which may reduce how often you need to replace a liner, depending on how much waste collects in your box and how frequently you empty it.

The plastic is described as high-strength, and the bags are intended to help contain moisture and reduce odor from the waste compartment. Those features target two common cleanup annoyances, but they don’t make the bags a substitute for emptying the drawer regularly. You’ll appreciate it if you want a drawstring liner in a multi-cat home or a busy routine and your litter box meets the stated fit requirements.

Key takeaways

• 80 bags total, supplied on four rolls of 20.
• Each liner measures 17.7 x 17.7 inches and has a drawstring closure.
• The stated fit is for compatible Ducksky models and bins with length plus width of 16 inches or less.
• The listing gives a per-bag capacity of 18–22 pounds, but doesn’t specify bag thickness or provide a full model-by-model compatibility list.

The main trade-off is straightforward: a bulk roll supply is convenient when the dimensions match, while a liner sold specifically for your exact litter box may be the simpler choice if its fit is unclear. It’s not for you if you can’t verify that your waste compartment meets the stated sizing guidance.

Should you buy it?

Choose these if your automatic litter box is a compatible model, its waste bin falls within the listed dimensions, and you want multiple drawstring bags ready for routine changes. The pack’s practical advantage is the combination of a four-roll supply and a closure that helps keep used litter contained on the way to the trash.

Skip them if you need confirmed compatibility with a different box, or if you can’t establish the waste drawer’s measurements from its specifications. The listing doesn’t name every supported model, so a low-effort cleanup routine is only a benefit once you know the liner will fit. For a verified match, the 80-count pack offers a straightforward replacement supply, for an uncertain fit, prioritize a liner with dimensions or compatibility details that clearly match your box.
