Litter Box Liners: How to Choose the Right Size and Fit

Quick answer

Choose a liner that matches your litter box size and style, allows enough overhang to grip the rim, and stays secure when your cat digs. Petmate Litter Box Liners are available in multiple sizes and styles to fit common pan shapes.

How to choose and use litter box liners step by step

1. Measure your litter box: Use a tape measure to record the inside length and width of the pan, plus the height of the rim. Common mistake: measuring only the outside, which leads to a liner that’s too small to overhang. Write the measurements down and take them with you when shopping.
2. Match liner size to pan size: Choose a liner size that covers the bottom and overhangs the rim on all sides. If your box is between sizes, size up rather than down. Checkpoint: the liner should drape over the rim by at least a few inches.
3. Check the rim and box style: High-sided and covered boxes may need a larger liner or a different style to reach over the rim. For covered boxes, make sure the liner doesn’t interfere with the lid. Common mistake: forcing a standard liner onto a high-sided box and leaving gaps.
4. Install the liner correctly: Spread the liner over the litter pan so it overhangs the rim on all sides, then press the center down to the bottom. Smooth out wrinkles. Checkpoint: the liner should sit flat without bunching at the corners.
5. Add litter and test for stability: Pour in your usual amount of litter and watch how your cat digs. If the liner slips or tears easily, try a different size or style. Common mistake: ignoring early signs of slipping and ending up with litter under the liner. Replace torn liners promptly to keep the box walls clean.
