Proper liner installation makes all the difference between a great experience and a frustrating one. Here's the definitive technique guide.
Step-by-Step Installation
1) Open liner fully before placing in box. 2) Insert open end first into the box. 3) Fold excess liner over the outside rim — aim for 2-3" of overhang on all sides. 4) If liner has a drawstring, run it along the outside of the rim. 5) Add litter on top of the installed liner. 6) Drawstring stays loose until it's time to remove.
Adding Litter Correctly
Pour litter slowly into the center first, then spread to corners. The weight of litter helps hold the liner flat. Add 3-4 inches of depth — enough to cover the liner surface fully. Don't add so much that the liner is stressed under the weight.
Removal Technique
1) Pull the drawstring to close the liner. 2) Lift the liner by the gathered top — it should hold all contents. 3) Place in a waste bag (if not compostable) or directly in compost bin. 4) The box beneath should be clean and require no scrubbing.
When to Change
Clumping litter with liners: scoop daily, full change every 1-2 weeks. Non-clumping with liners: complete change every 2-3 days. If you smell ammonia when approaching the box, don't wait — change it now.

The most common cause is insufficient overhang — the liner edge needs to fold over the rim. Try pulling the liner up further on the sides and securing the drawstring snugly before adding litter.
Not recommended. Liners accumulate bacteria and urine soaking even when they look intact. The health risk and smell aren't worth the small cost savings.
With good liner use, box cleaning can be reduced to monthly wipe-downs instead of weekly scrubbing. However, occasional box cleaning is still recommended to catch any seepage and maintain hygiene.
