ZOMISIA Large Cat Litter Box Liners, 37" x 18", 40 Count

At 37" x 18", these ZOMISIA plastic liners are sized for large litter pans and come in a 40-count pack. Each bag has a drawstring closure and perforated edges for dispensing, so the basic routine is straightforward: separate a liner, fit it over the pan, then use the drawstring to close the bag when it is time to remove the litter.

The liners are unscented and described as extra thick, with a stated thickness of 2 mils. They are intended for most traditional open-style litter boxes, but the listed dimensions are the clearest guide when deciding whether a liner will suit a particular pan.

Size & fit

The 37" x 18" format is the main fit detail to compare with your litter tray. The product is described as jumbo and intended for most traditional open-style boxes, while customer feedback on size is mixed: some buyers say the liners work well for larger boxes, and others feel they are smaller than stated. If your pan has an unusual shape or you need a precise fit, compare its dimensions with the bag measurements rather than relying on the “large” label alone.

For a routine litter change, the perforated edges are meant to let you pull off one bag at a time, and the drawstring provides a way to close it for disposal. It suits you if you want disposable liners with those features and your pan matches the stated size. You may want to skip it if a guaranteed fit for a specific tray is essential, since buyer feedback on sizing is not consistent.

Why it’s worth it

These liners combine a large stated format with a drawstring and perforated separation, rather than relying on a plain bag that needs to be tied separately. The product description says the 2-mil plastic is designed to resist tearing and leaks, those are intended benefits, not a guarantee against every scratch, spill, or litter-box setup. The unscented material is also a practical detail for households that prefer litter supplies without added fragrance.

Customers often praise the thickness and say the bags make litter changes easier. Some also report that they work with larger sifting boxes. Feedback is less uniform on the drawstring, so that feature may not feel equally convenient to every buyer. What matters most: do the dimensions match your pan? That is the key question before choosing this pack over a liner in a different size or format.

Buying verdict

This pack is worth considering if you want 40 unscented plastic liners in a stated 37" x 18" size, with perforations for dispensing and a drawstring for closure. Its strongest buying case is convenience during regular litter changes, supported by buyer comments about easier cleanup and the liners’ thickness. It is a more feature-specific choice than a basic bag because it includes both a drawstring and perforated separation, shoppers who prioritize an exact fit should give the mixed sizing feedback more weight than the jumbo label. The listed dimensions, rather than the product name alone, are the sensible basis for deciding whether it belongs with your litter box.
