Whisker Litter-Robot Waste Drawer Liners 25-Pack — Drawstring, Heavy-Duty 9–11 gal Fit

These are 25 heavy-duty, drawstring waste drawer liners made by Whisker to fit all Litter-Robot models for fast, tidy disposal.

Keep your automatic litter system clean and odor-controlled with waste drawer liners sized specifically for the Litter-Robot. The liners are engineered to hold a large volume of clumps and debris so you can swap out full bags quickly without spills. Designed and assembled in the USA, these liners pair with Whisker devices and the Whisker app to simplify maintenance and reduce the time you spend scooping.

How do these liners make emptying the waste drawer easier?

Each liner is crafted to match the shape and dimensions of the Litter-Robot waste drawer so installation and removal are straightforward. The drawstring closure secures contents for mess-free transport to the trash. Because the bags hold a high capacity, you’ll change liners less often than with standard garbage bags.

• Custom fit for all Litter-Robot models for a snug installation
• Drawstring closure for secure removal and tidy disposal
• Holds 9–11 gallons to reduce frequency of bag changes
• 25 liners per pack for several weeks of use in most households

Will these liners work with my Litter-Robot 3 or 4?

Yes—installation is tailored to each model. For the Litter-Robot 4, stretch the liner rim over the drawer edge; for the Litter-Robot 3, tuck the rolled edges into the drawer’s four tabs. The liners pack flat for easy storage between uses.

• Litter-Robot 4: wrap the edges over the waste drawer rim
• Litter-Robot 3: push rolled edges into the four drawer tabs
• Flat-packed liners save space until needed

How durable and odor-resistant are these liners?

These heavy-duty bags are thicker than typical kitchen trash liners to resist punctures from litter and clumps. While not a replacement for odor filters, the secure drawstring and capacity reduce the chance of leaks and help contain smells until you dispose of the bag. They’re intended for single-use disposal to keep the drawer interior clean.

• Reinforced material to prevent tearing when full
• Large capacity minimizes overfilling and spills
• Single-use design supports a cleaner drawer interior

How do these liners fit into the Whisker system and routine?

The liners were created to work with Whisker products and the Whisker app notifications. When the app tells you the waste drawer is full, pull the drawer, cinch the drawstring, and replace with a fresh liner—no scooping required. The 25-count pack keeps a steady supply on hand for busy homes.

• Compatible with Whisker Litter-Robot units and app notifications
• Streamlines routine maintenance and reduces manual scooping
• 25 bags per pack for convenient, repeated replacements

Who this product is for: These liners suit cat owners who use a Litter-Robot and want a cleaner, faster way to handle waste. If you prefer tidy, single-step disposal, appreciate a drawstring closure, and value liners made to fit your automatic litter system, this 25-pack offers a reliable supply. It’s also a practical choice for multi-cat households or anyone who wants fewer trips to the trash can and less time cleaning the waste drawer.
