Three measurements to take before choosing a liner

Start with the waste drawer

Check the exact litter box model and read its manual before removing the drawer. A liner needs to fit the waste drawer rather than the outside dimensions of the machine.

Measure the opening and depth

With the drawer empty, measure the inside opening from front to back and side to side. Then measure from the rim to the base. Record the units with each measurement.

Check the fixing points

Look for clips, grooves, retaining rings and sensors. The bag needs to reach the base and sit securely around the rim without covering sensors or restricting moving parts. Measurements alone do not guarantee compatibility.

Open the fit guide and compare the final product dimensions with your exact model before ordering.
