Elastic litter box liners stay put because the band grips the rim, like a fitted sheet on a mattress. That makes them the better choice for oversized pans, where a drawstring bag tends to slide. The Alfapet Extra Giant 30-count is the pick here for XL and bigger pans, and the 24-count is the one for medium and large boxes.

Detailed Reviews
Alfapet Elastic Cat Litter Box Liners, Extra Giant, 30 Count🏆 Editor’s Pick
| Count | 30 liners |
| Size | 37 in x 18 in, 1.5 mil |
| Capacity | 20 lb (listed) |
| Feature | Sta-Put elastic, no tie strings |
What We Found
The Alfapet Extra Giant liners measure 37 x 18 inches and list a 1.5 mil thickness and a 20 lb capacity. The Sta-Put elastic band is meant to hold the bag on the rim, so there’s no overhang to tuck and no tie strings to manage.
The tradeoff is thickness. 1.5 mil is thinner than the 2 mil listed on some drawstring liners, so a cat that digs hard puts more demand on it. Trimmed claws help.
💬 My Take
I’d start here if your pan is XL or bigger. Fit is the reason to buy elastic, and this is the size built for it. The 1.5 mil spec is the thing to watch with a heavy digger.
Who It’s For
Owners of XL, Giant or X-Giant pans who want a liner that stays on the rim. Suits most cats. For a hard digger, consider a thicker drawstring liner instead. For other oversized options, see our jumbo litter box liners guide.
✅ Pros
- Extra giant size fits oversized pans.
- Sta-Put elastic is meant to hold the bag on the rim.
- No tie strings to handle.
- 30-count pack gives you a lower cost per liner to work out.
❌ Cons
- 1.5 mil is thinner than some drawstring liners.
- May be too large for small boxes.
- A 30-count pack takes storage space.
Alfapet Elastic Cat Litter Box Liners, Large to X-Giant (20 Count per listing title)👑 Premium Pick
| Count | See listing |
| Size | 37 in x 18 in, 1.5 mil |
| Feature | Sta-Put elastic, multi-size fit |
| Pan fit | Large, X-Large, Giant, X-Giant |
What We Found
This pack uses the same 37 x 18 inch size and 1.5 mil film as the extra giant 30-count, and it’s listed to fit pans from Large up to X-Giant. The elastic band keeps it positioned during use.
The practical question is price per liner. If it costs more per bag than the 30-count, the only reason to pick it is a smaller box in your cupboard.
💬 My Take
Same bag, smaller pack. Run the price per liner against the 30-count before you decide. I’d only pick this one for storage reasons or if it’s cheaper per bag.
Who It’s For
Owners with Large through X-Giant pans who don’t need a 30-pack, or who want to test elastic liners before buying more.
✅ Pros
- Fits several oversized pan sizes, Large through X-Giant.
- Sta-Put elastic prevents slippage.
- 1.5 mil film for everyday use.
❌ Cons
- Smaller pack may cost more per liner than the 30-count.
- Overkill for an average-sized box.
- Same 1.5 mil thickness as the 30-count.
Alfapet Disposable Elastic Cat Litter Box Liners, 24 Count, Medium and Large💰 Best Value
| Count | 24 liners |
| Size | 31 in x 17 in, 1.5 mil |
| Feature | Sta-Put elastic, tear-resistant |
| Pan fit | Medium and large |
What We Found
The 24-count pack measures 31 x 17 inches with the same 1.5 mil film and Sta-Put elastic as the larger Alfapet packs. It’s sized for medium and large pans, so the elastic reaches the rim without stretching too far.
It isn’t built for giant pans. If your pan is XL or bigger, the band won’t reach, and the 37 x 18 inch Alfapets are the fit.
💬 My Take
The easy pick for a standard medium or large pan. The smaller size means less slack and less to bunch. Measure first, because it won’t stretch to a giant box.
Who It’s For
Owners of medium and large pans who want elastic liners at a reasonable count.
✅ Pros
- Sta-Put elastic gives a secure fit.
- 24-count pack balances value and storage.
- Tear-resistant film handles everyday clawing.
❌ Cons
- Smaller than the extra giant variants.
- Won’t fit oversized pans.
- No odor control listed.
So Phresh by Petco Elastic Cat Litter Box Liners, 36 in L x 14 in W, 40 Count💵 Budget Pick
| Count | 40 liners |
| Size | 36 in L x 14 in W |
| Feature | Elastic top with dispenser box |
| Design | Tear-resistant |
What We Found
The So Phresh liners come 40 to a dispenser box, and the listing says the elastic top fits securely and keeps litter contained. At 36 x 14 inches, the bag is long and narrow, so it suits longer pans better than wide ones.
No thickness rating is listed in the specs above, so compare it to the 1.5 mil Alfapets before you assume it’s equal.
💬 My Take
Good as a budget pack if your pan is on the narrower side. The 14 inch width is the limiting spec, so measure before you buy.
Who It’s For
Owners of standard-width pans who want a high count and a dispenser box.
✅ Pros
- 40-count pack gives a low cost per liner to work out.
- Elastic top is listed to fit securely.
- Dispenser box keeps liners together.
❌ Cons
- 14 inch width limits pan compatibility.
- No thickness rating listed.
- No odor control features listed.
Fresh Kitty Litter Box Liners, 10 Count, Durable, Easy Clean Up🏆 Editor’s Pick
| Count | 10 liners |
| Closure | Easy-pull drawstring |
| Material | Ultra-thick, leak-proof |
| Scent | Lavender Vanilla Odor-Zorb |
What We Found
The Fresh Kitty liners use a drawstring rather than an elastic band, which makes them a useful contrast to the other four. They’re listed as ultra-thick and leak-proof, with a Lavender Vanilla Odor-Zorb scent.
The scent is the catch. Some cats dislike fragrance in the box, and the listing doesn’t state a mil rating or a size here, so check both on the product page.
💬 My Take
Pick this one if you want a drawstring and odor control over an elastic fit. For the focus of this guide, elastic liners, it’s the odd one out. Watch your cat’s reaction to the scent.
Who It’s For
Owners of standard pans who prefer a drawstring and a scented liner for odor control. For another widely sold brand, see our Tidy Cats litter box liners guide.
✅ Pros
- Drawstring makes removal and carrying simple.
- Odor-Zorb scent for odor reduction.
- Ultra-thick film is listed as leak-proof.
❌ Cons
- Only 10 liners per pack.
- Scented, so it may bother sensitive cats.
- Size and mil rating aren’t listed here.
Elastic vs Drawstring Liners
| Factor | Elastic liners | Drawstring liners |
|---|---|---|
| How it stays on | Band grips the rim | Bag is draped and tucked |
| Slipping | Low if the size matches the pan | Depends on tucking and bag size |
| Disposal | Peel the band off the rim, gather the top, knot it | Cinch the cord, lift, toss |
| Strings | None | Cord |
| Size sensitivity | High. The band must reach the rim. | Lower. Overhang gives you slack. |
| Best for | Oversized or awkward pans | Standard pans and heavy dumps |
Drawstring bags have one real advantage: when the bag is heavy, a cord makes carrying easier. Elastic wins on fit, and that’s where most liner trouble starts.
How to Measure and Fit an Elastic Litter Box Liner?
Measure first
- Measure the outside length and width of the pan at the rim.
- Measure the depth.
- Match the pan size on the listing, such as Large, X-Large, Giant or X-Giant, to your pan.
- Check the bag’s dimensions against your numbers, and note the thickness.
Fit it step by step
- Wash and fully dry the pan.
- Unfold the liner and center it over the pan.
- Stretch the band over one corner, then the opposite corner.
- Work along the sides until the band sits on the rim all the way around.
- Smooth the bottom so there are no folds for claws to catch.
- Add litter in stages, to your usual depth.
- On dump day, peel the band off the rim, gather the top, knot it and toss it.
What to Look For Before Buying
Size compatibility
Elastic liners are the most size-sensitive type. Check the pan size on the listing and the dimensions of the bag. Too small and the band won’t reach. Too big and it sags and bunches. Our guide on what size litter box liner you need goes deeper.
Material thickness
Thickness is measured in mils. The Alfapet liners list 1.5 mil. Some drawstring liners list 2 mil. Thicker film resists claws better, and a few listings, like So Phresh and Fresh Kitty here, don’t state a rating. If you want a greener option, see compostable litter box liners.
Elastic security
The band is the reason to buy elastic. Look for a named grip feature like Sta-Put, and check how snug it sits on your rim in the first day.
Count and cost
Divide the box price by the count. The 30-count Alfapet and the 40-count So Phresh are the bulk options. If you’re tempted to use kitchen bags instead, read can you use trash bags as litter box liners first.
Scent
Scented liners can help with odor, but some cats dislike fragrance. If yours is picky, choose unscented.
- ☐ I’ve measured my pan’s length, width and depth.
- ☐ The listing’s pan size matches mine.
- ☐ I’ve checked the thickness, or I know it isn’t listed.
- ☐ The count gives a cost per liner I’m happy with.
- ☐ My cat doesn’t dig through the pan floor, or I’ll accept the risk.
- ☐ It isn’t for an automatic box.
Troubleshooting Elastic Liners
| Problem | Likely cause | Fix |
|---|---|---|
| Band pops off the rim | Liner too small or rim too thick | Size up or use a larger liner |
| Liner sags or bunches | Liner too large | Choose a smaller size, smooth the bottom |
| Cat tears the liner | Digging, long claws, thin film | Trim claws, try thicker film or no liner |
| Urine pools under the bag | Gaps at the rim | Reseat the band all around, add litter in stages |
| Cat avoids the box | Scent, crinkle, or an unrelated issue | Remove the liner and rule it out, see a vet if it continues |
| Box still smells | Stale litter or a scratched pan | Change litter on schedule, replace the pan |
Frequently Asked Questions
What are elastic litter box liners?
They’re litter box bags with an elastic band around the opening. The band stretches over the pan’s rim and holds the bag in place, so you don’t tuck an overhang or tie strings. The Alfapet liners here use Sta-Put elastic, and the So Phresh liners use an elastic top.
Do elastic liners fit all litter box shapes?
They fit most rectangular and oval pans if the size is right. Match the pan size on the listing, such as Large, X-Large, Giant or X-Giant, to your pan, then check the bag’s dimensions. A band that’s too small won’t reach the rim, and one that’s too big can sag.
How do I put an elastic liner on a litter box?
Center the bag over a clean, dry pan. Stretch the band over one corner, then the opposite corner, then the sides. Run your hand around the rim and smooth the bottom, then add litter in stages.
How do I measure my pan for an elastic liner?
Measure the outside length and width at the rim, and the depth. Compare them to the bag’s listed size and to the pan fit named on the listing. When in between, size up slightly and check how snug the band is.
Are elastic liners better than drawstring liners?
Elastic liners stay on the rim better and need no tucking. Drawstring liners are easier to cinch and carry when the bag is heavy. Pick elastic for oversized or awkward pans, and drawstring if you do a lot of heavy dumps.
Are scented liners safe for cats?
Many cats tolerate them. Strong fragrance can put a sensitive cat off the box, so start with unscented or a light scent and watch your cat’s behavior. The Fresh Kitty liners here are scented with Lavender Vanilla.
How often should I replace a litter box liner?
At every full litter change, not on a fixed schedule. 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 tears or the box smells.
Will elastic liners stop litter tracking?
No. Tracking comes from paws, not the pan. A snug liner keeps litter and urine off the pan walls, but a litter mat outside the box does the work of catching scatter.
Are no-tie liners safer than liners with tie strings?
Some owners prefer no strings so there’s nothing for a curious cat to chew or tangle in. It’s a preference more than a proven safety gap. Store spare liners out of reach either way.
Can cats tear elastic liners?
Digging cats can, especially through thinner film. The Alfapet liners list 1.5 mil. Trim claws, smooth the bottom so there are no folds, and consider a thicker liner or going without if the bag keeps shredding. For more, read whether cats scratch through litter box liners.
Do elastic liners work in automatic litter boxes?
No. Automatic boxes use bags sized for their waste drawer. Elastic liners are made for open pans.
🎯 Final Verdict
For an XL, Giant or X-Giant pan, the Alfapet Extra Giant 30-count is the pick, because the elastic is sized to reach the rim and the 30-pack gives you a low cost per liner to work out. For medium and large boxes, the 24-count Alfapet is the better fit. Both list 1.5 mil, so a heavy digger may need a thicker drawstring liner instead.
Measure your pan, match the size on the listing, and divide the price by the count before you buy.
