Yes, litter box liners are worth it if you dump and wash the whole box on a schedule and your cat leaves plastic alone. Skip them if your cat shreds bags or you mostly scoop and top off. The payoff is time, not money, and a liner that doesn’t fit your pan is worse than none.
I compared five popular liners on listed thickness, size, closure and compatibility, so you can match one to your pan and your cat. This guide also covers the cost per change, how to set a liner up so it stays put, and the mistakes that cause leaks. For liners of every type, see our best litter box liners guide.

⚡ Quick Verdict
Worth it: multi-cat homes, full dump-and-wash routines, sore wrists, and automatic boxes that need bags. Not worth it: diggers, owners who rarely dump, and anyone avoiding extra plastic. For manual pans, the Jonny Cat Jumbo 15-count is the pick here. For automatic boxes, go with the 150-count bags made for them.
Are Litter Box Liners Worth It?
A liner is a plastic bag that sits in the pan. On a full litter change you pull the drawstring, lift the bag out, and toss it. The pan stays mostly clean, so you skip the scrubbing. That’s the whole value proposition, and for a lot of owners it’s enough.
| Question | Liners | No liners |
|---|---|---|
| Dump day effort | A few minutes | Dump, scrub, rinse, dry |
| Cost per change | Price of one bag | Soap and water |
| Odor | Keeps urine off the pan, no effect on litter | Pan can absorb odor over time |
| Cat acceptance | Most don’t care, diggers may snag claws | Nothing to snag |
| Plastic waste | One bag per change | None extra |
✅ Advantages
❌ Disadvantages
When liners are not worth it
If your cat digs hard, you’ll fight a crumpled bag every day. If you scoop daily and rarely dump, the bag saves little. And if you’d rather cut plastic, a quick wash does the job at no cost, or you can try compostable litter box liners. A scratched pan that holds odor needs replacing, and a liner won’t fix that.
Quick worth-it checklist
- ☐ I do a full dump and wash at least every few weeks.
- ☐ My cat doesn’t shred bags or dig through the pan floor.
- ☐ I know my pan’s length and width.
- ☐ I’m fine paying for one bag per change.
- ☐ My cat accepts the liner without avoiding the box.
If you ticked most of these, buy a liner. For a closer look at the no-liner side, see our guide on litter box liners vs no liners. For the full list of upsides and downsides, read our litter box liners pros and cons guide.

Jonny Cat Litter Box Liners Heavy Duty, Tear & Leak Resistant Jumbo 15 |
The Jonny Cat Litter Box Liners Heavy Duty, Tear & Leak Resistant Jumbo 15ct are built for manual litter pans. The heavy-duty material resists tears and leaks, and the drawstring closure lets you tie off the bag with little contact with used litter.
The listing calls it the number one selling liner in America. That’s a sales claim, not a test result, but it does mean a lot of owners buy it. The jumbo size fits most traditional manual pans, and the lift, tie, toss routine keeps dump day short.
Why It Works
- ✓ Heavy-duty material resists tears and leaks
- ✓ Drawstring closure for easy disposal
- ✓ Reduces contact with used litter during cleaning
- ✓ Jumbo size fits most traditional manual litter pans
Important Considerations
- • May not fit all litter box shapes
- • Unscented, which won’t suit owners who want a scented liner
- • Price varies by retailer

Fresh Step Drawstring Cat Litter Box Liners, Scented, 2.5 ft x 17 in |
The Fresh Step liners are lightly scented and sized 2.5 ft x 17 in. The thick film resists rips and punctures, and the drawstring ties off the bag so loose granules stay inside.
They fit most large oval or rectangular pans and can be adjusted for a smoother fit. The scent is light, but some cats dislike fragrance in the box, so watch your cat’s reaction.
Why It Works
- ✓ Easy lift-out cleanup
- ✓ Drawstring close keeps litter contained
- ✓ Thick film resists rips and punctures
- ✓ Lightly scented to manage litter box smell
Important Considerations
- • May not fit all litter box sizes
- • Scent may bother some cats and owners
- • Price varies by retailer

150 Count Cat Litter Box Bags for Automatic Cat Litter Box with Drawstring |
These 150-count bags are made for self-cleaning litter boxes. They’re pre-separated, so you can pull one without tearing it. The LDPE material has double-sealed edges, and the drawstring is reinforced for a tight seal.
The 150 count suits multi-cat homes that go through bags quickly. Check your box model before you order, since automatic boxes use specific shapes.
Why It Works
- ✓ Pre-separated for easy grabbing
- ✓ LDPE material with double-sealed edges
- ✓ Reinforced drawstring for a tight seal
- ✓ Large pack suits multi-cat households
Important Considerations
- • Not compatible with all automatic litter boxes
- • May not fit all litter box sizes

Jonny Cat Litter Box Liners: Heavy Duty, Tear & Leak Resistant, Drawstring Close, Jumbo, 5 Count |
This is the same liner as the 15-count pack in a 5-count box. The heavy-duty material resists tears and leaks, and the drawstring closes the bag for disposal.
It’s a good way to test whether your cat tolerates a liner before you commit to a bigger box. The trade-off is that each bag costs more than it would in the 15-count.
Why It Works
- ✓ Heavy-duty material resists tears and leaks
- ✓ Drawstring closure for easy disposal
- ✓ Low commitment for a trial run
- ✓ Jumbo size fits most traditional manual litter pans
Important Considerations
- • Smaller quantity means more frequent reordering
- • Unscented liners may not suit every owner
- • Price varies by retailer

FortiCrest Cat Litter Box Liners, 30 Count, Large 37 in x 18 in, 2.8 Mil Thick |
The FortiCrest liners are the only ones here that list a thickness: 2.8 mil. The listing says the high-density material resists claw damage and supports up to 30 lbs, and it fits both standard and larger pans. That makes them the pick for heavy litter or larger pans.
A drawstring lets you remove the bag without dirtying your hands. For heavy loads, lift from the body of the bag rather than the drawstring.
Why It Works
- ✓ Thickest listed spec of the five, at 2.8 mil
- ✓ Large 37 in x 18 in size fits standard and larger pans
- ✓ Listed to support up to 30 lbs
- ✓ Drawstring closure for quick removal
Important Considerations
- • May not fit all litter box shapes
- • Heavy loads are best lifted from the bag body
- • Price varies by retailer

How to Choose the Right Litter Box Liner?
Size and thickness matter most. A great bag in the wrong size bunches, slips and leaks.
- Size: Measure your pan’s length and width, then match them to the bag. Oval and high-sided boxes need extra tucking.
- Thickness: Thicker resists claws. Look for a mil rating, like the 2.8 mil on the FortiCrest.
- Closure: A drawstring ties off the bag for clean disposal. Check that the cord is reinforced.
- Scent: Unscented is the safe default for picky cats. Lightly scented, like Fresh Step, works if your cat doesn’t mind.
- Pack size: Match the count to your dump schedule and number of cats.
- Box type: Automatic boxes need bags made for them. Don’t use standard liners in one.
How to Use a Litter Box Liner Without Leaks?
- Empty and dry the pan so moisture isn’t trapped under the bag.
- Lay the liner flat and push it into the corners.
- Fold the extra over the rim and tuck it tight. Use clips or clothespins if it keeps slipping.
- Pour in litter slowly to your usual depth.
- Scoop daily with a gentle motion so the scoop doesn’t catch the plastic.
- On dump day, pull the drawstring closed, lift from the bag body, tie it off and bin it.
- Wipe the pan, check it for scratches, and fit a fresh bag.
Common Mistakes With Litter Box Liners
- Wrong size: A bag that’s too small slips, and one that’s too big bunches. Measure first.
- Loose rim: Untucked edges let the bag sink under the litter.
- Pouring litter too fast: It shifts the bag and leaves gaps.
- Using standard liners in an automatic box: The shape won’t match.
- Ignoring a scratched pan: A liner doesn’t fix a pan that holds odor.
- Skipping the cat test: If your cat avoids the box after you add a liner, remove it.
Prevention tip: if the bag still shifts after tucking, switch to a thicker liner or a closer size match.

Frequently Asked Questions
Are litter box liners worth it?
For most owners who do a full dump and wash, yes. A liner turns a scrubbing job into a lift, tie and toss job. They aren’t worth it if your cat digs hard enough to shred the bag, or if you rarely dump the box and mostly scoop and top off.
Do litter box liners save money?
Not directly. A liner is an extra cost on every full change. What you save is time and effort, and some owners also get a longer life out of the pan because urine stays off the plastic. Divide the box price by the bag count to see what each change costs you.
Do litter box liners help with odor?
A little. They keep urine from soaking into the pan floor and corners, where old smell builds up. They don’t touch the litter itself, so daily scooping and regular full changes still decide how the room smells.
Do cats hate litter box liners?
Most don’t notice them. Some cats dislike the crinkle or snag a claw while digging. If your cat starts going outside the box after you add a liner, take it out and see if the problem stops.
What size litter box liner do I need?
Measure your pan’s length and width, then compare them to the bag’s listed size. The Fresh Step liners here are 2.5 ft x 17 in, and the FortiCrest are 37 in x 18 in. Jumbo bags fit most manual pans, but oval and high-sided boxes can leave slack, so tuck it tight.
How thick should a litter box liner be?
Thicker resists claws better. Liner thickness is measured in mils. The FortiCrest liners list 2.8 mil. Not every listing states a rating, so check the product page before buying.
Do litter box liners work in automatic litter boxes?
Only the ones made for them. Automatic boxes use a specific bag size and shape, so a standard drawstring liner won’t fit. The 150-count bags in this guide are made for self-cleaning boxes, but check compatibility with your model first.
Can I use trash bags instead of litter box liners?
You can in a pinch. Kitchen bags are thinner and slippery, and they bunch under the litter. A liner with a drawstring is cut for the pan and ties off cleanly.
Can I flush litter or litter box liners?
No. Clumping litter can clog plumbing and plastic liners don’t break down in a sewer system. Tie the bag and put it in the trash.
How often should I change the liner?
Every full litter change. A common guideline is every 2 to 4 weeks for clumping litter and about once a week for non-clumping, with daily scooping either way. Change it sooner if it’s torn or the box smells.
