Your cat’s robot litter box does the scooping, but the waste drawer still needs a liner you can trust. A flimsy bag can tear mid-removal, leak odors, or simply not fit your specific model, turning a five-minute task into a messy ordeal. The right liner keeps the drawer clean and makes disposal nearly effortless.

That is exactly why we put together this guide to the best CATLINK waste bags in 2026. We reviewed top-rated options from ANWA and CATLINK, focusing on compatibility, durability, and everyday usability for automatic litter box owners.

Check Compatibility With Your Litter Box Model

Not all waste bags fit every robot litter box. The ANWA 40 Count Automatic Litter Box Bags are designed for LR Series models including 3, 4, 5, 5 Pro, and EVO, while CATLINK trash bags are built specifically for OPEN-X, SCOOPER, and Scooper Prox models. Some bags are labeled for multiple models, but you should always verify the dimensions against your unit.

Before ordering, measure your litter pan and waste drawer. If the length plus width of the pan exceeds 25 inches, a standard liner may not sit flush. When in doubt, check our CATLINK litter box accessories roundup for model-specific recommendations.

Evaluate Material Strength and Leak Resistance

The best CATLINK waste bags use heavy-duty, extra-thick material to handle clumping litter without tearing. ANWA bags are marketed as heavy-duty and extra thick, while CATLINK liners are made to hold heavy loads without breaking or leaking. Reinforced seams also help prevent splits at the edges.

Durability matters even more in multi-cat homes. If you have more than one cat, our guide to the best litter box liners for multiple cats offers additional insight into high-traffic materials.

Prioritize Odor Control and Easy Sealing

Drawstring closures make a huge difference when emptying a dirty litter drawer. Simply pull the bag closed, lift it out, and toss it without touching waste or tying knots. The 80 Pack CATLINK Trash Bags for Scooper Prox Series even claims to lock in odors with a dirt-resistant design.

For an even more airtight setup, consider pairing your liner with odor-absorbing pads. Explore the best PETKIT smart litter box accessories if you use a PETKIT unit instead. Odor locking is especially important in covered litter boxes or small rooms.

Think About Bulk Value and Replacement Frequency

Automatic litter box bags get changed several times a week, so buying in bulk saves you from running out at the worst moment. The 80 Pack CATLINK Trash Bags for Scooper Prox Series includes four rolls of 20 bags, while both the ANWA 40 Count and CATLINK 40 Pack options offer two rolls. That means more time between reorders.

Keep in mind that larger packs take up more storage space. If you live in a small apartment, a 40-count pack may be the smarter choice. Our roundup of best extra large cat litter box liners can help if you prefer oversized alternatives.

Final Thoughts

Choosing the right liner comes down to your litter box model and how much convenience you want at the end of the week. For LR Series owners, the ANWA 40 Count Automatic Litter Box Bags deliver a dependable drawstring fit with tear-resistant material. For anyone using an OPEN-X or SCOOPER, the CATLINK 40 Pack Trash Bags for OPEN-X & SCOOPER is the clear match, with heavy-duty construction designed around that exact waste drawer. Pick the bag that matches your robot, and you will spend less time scrubbing and more time enjoying your cat.

Frequently Asked Questions

No, not all CATLINK trash bags are universal. For example, the CATLINK 40 Pack Trash Bags for OPEN-X & SCOOPER is not suitable for the SCOOPER Luxury Pro or SE series, while the 80 Pack option is designed for the Scooper Prox series. Always match the bag to your exact model. A quick lookup in your litter box manual can save you from buying the wrong size.

How often should you replace waste bags in an automatic litter box?

Most automatic litter box owners replace the waste bag every two to five days depending on the number of cats. In 2026, popular options like the ANWA 40 Count and CATLINK 40 Pack are designed for easy, quick swaps so you can stay on a consistent schedule. If you notice odors before the drawer looks full, it is time to change the liner.

Are drawstring litter box bags better than standard liners?

Yes, drawstring bags let you pull the liner closed and lift it out with one motion. This reduces contact with waste and prevents spills. The 80 Pack CATLINK Trash Bags for Scooper Prox Series includes a pull-and-lift design with automatic sealing. It is a small upgrade that makes a big difference.

Can I use regular trash bags in my automatic litter box?

Using regular trash bags can work in some models, but they rarely fit the waste drawer properly and may tear or bunch up. For the best fit and odor control, stick with bags designed for your machine.
