Buying Guide
Size and Compatibility
Before you buy, measure your litter box’s waste drawer. The length plus width should be less than 25 inches for these bags to fit. Both products we reviewed fit popular models like the Litter Robot 3, 4, and 5, but always double-check your drawer dimensions.
Durability and Thickness
Thicker bags resist tearing and leaks, crucial for heavy waste loads. Heavy-duty LDPE material, used in both featured products, offers strength without adding bulk. Look for extra-thick construction if you have multiple cats or large clumps.
Drawstring Convenience
A reliable drawstring makes disposal effortless. Simply pull the strings to seal the bag securely, keeping your hands clean and odors contained. Both the ANWA and KropBom bags feature robust drawstring designs for easy lifting and tying.
Value and Quantity
Consider how often you change the liner. For two cats, you might swap the bag twice a week. A 40- or 45-count pack lasts over a month. For more cleaning essentials, see our top cleaning tools guide.
Final Thoughts
Whether you need a trusted value pack for your Litter Robot or extra durability for a multi-cat home, your choice comes down to a few details. The ANWA 40 Count Automatic Litter Box Bags offer a solid, heavy-duty option with a straightforward fit for most standard drawers, while the KropBom 45 Count Automatic Litter Box Bags Liners provide a slightly larger capacity with a bonus catnip toy, ideal for households that need a little extra. Pair either with a good scoop set from our best litter scoop guide to keep your cat’s space clean and odor-free all year long.

Frequently Asked Questions
How often should I change the waste bag in my automatic litter box?
Most owners with one or two cats replace the bag every 3 to 4 days. Heavier use or multiple cats may require more frequent changes, depending on your litter box’s capacity.
Can I use regular trash bags in my Litter Robot?
Standard trash bags often don’t fit the drawer correctly and can cause jams or poor sealing. Specialized liners designed for your model ensure a snug fit and proper function.
Are these bags eco-friendly or biodegradable?
Currently, most heavy-duty litter box bags are made from traditional LDPE plastic, which is not biodegradable. Look for brands that use recycled materials if sustainability is a priority for you in 2026.
What if my litter box drawer is slightly larger than 25 inches?
Bags designed for up to 25-inch drawers may fit tightly or tear. Check the manufacturer’s specifications for your specific model, or consider generic extra-large liners for larger drawers.
