Frisco High Sided Cat Litter Box 2026: Honest Review & 6 Picks

The high-sided litter box exists for one specific cat: the enthusiastic digger who flings litter like a pitching machine, or the stand-up peer whose aim clears a standard pan’s walls. If you’ve ever found litter scattered six feet from the box — or worse, urine on the wall behind it — you know the problem. Frisco, Chewy’s house brand, makes the best-selling answer: an open-top box with 10-inch walls and a low front entry, priced like a budget box but reviewed like a premium one.

The honest note: the Frisco High Sided box is a Chewy exclusive, so you can’t price-shop it on Amazon — and its 4.8-star average across 7,000+ Chewy ratings deserves a closer look at what the unhappy minority actually says. This review covers the Frisco box itself, the bundle version, and the best Amazon-available alternatives for anyone who doesn’t shop at Chewy.

Frisco High Sided Cat Litter Box at a Glance

Prices shift constantly — check before you buy. Frisco products are sold only at Chewy.

1. Frisco High Sided Cat Litter Box (XL, 24-in) — Best Overall

The main event: a 24″ x 18″ x 10″ open-top pan with high walls on three sides and a lowered 5.6-inch front entry. The design logic is sound — tall walls contain the enthusiastic digger’s scatter and the high-peer’s spray, while the low entry keeps it accessible for kittens, seniors, and cats that refuse to jump. At roughly 4.8 stars across more than 7,000 Chewy ratings (with 92%+ positive marks on durability, cleaning, and size), it’s one of the highest-rated litter boxes Chewy sells. Owners of 18-lb cats call it “huge” in the best way, and multi-cat households buy them in pairs.

The complaints are worth hearing. First, it’s genuinely big — one owner admitted fault for not measuring, finding it too large for the planned spot. Second, that size means it takes noticeably more litter to fill to a proper depth. Third, it’s open-top by design, so it doesn’t trap odor the way a covered box does, and the low entry still lets some litter escape — several owners pair it with a mat and call that the complete solution. Cleaning-wise, urine can cling to the tall walls, so a quick wipe during scooping keeps it fresh.

Specs: 24″ L x 18″ W x 10″ H · 5.6″ front entry height · open-top, high walls on three sides · Chewy-exclusive · ~4.8/5 from 7,000+ Chewy ratings.

Pros: 10-inch walls genuinely contain diggers and high-peers; low entry works for kittens and seniors; roomy enough for very large cats; excellent rating history.

Cons: large footprint — measure your space; needs more litter to fill; open top doesn’t trap odor; low entry still lets some litter out (use a mat).

Verdict: The best-selling high-sided box for good reason — just measure first. Chewy-exclusive; no Amazon link exists.

2. Frisco High Sided Litter Box + Litter Mat Bundle — Best Bundle

Same 24″ x 18″ x 10″ box, bundled with Frisco’s large rectangular litter mat — the bundle Chewy sells for owners who want the complete scatter solution in one order. The mat catches what the low entry lets through, which addresses the main box’s most common residual complaint. The bundle listing carries the same ~4.8-star rating (around 180 ratings on the bundle page), and owners specifically praise the tall sides plus easy kitten entry.

The honest math: bundles are convenient, not always cheaper — compare the bundle price against the box and mat separately before assuming a deal. And the mat is a standard Frisco litter mat, not a magic scatter-ender; heavy diggers will still defeat any mat eventually.

Specs: Same 24″ x 18″ x 10″ box with 5.6″ entry · plus Frisco large rectangular litter mat · Chewy-exclusive.

Pros: one order solves box + scatter; mat addresses the low-entry litter escape; same highly rated box.

Cons: bundle pricing isn’t always a discount — compare; Chewy-only; mat won’t stop determined diggers entirely.

Verdict: The convenient buy — box plus mat in one shot. Chewy-exclusive; no Amazon link exists.

3. IRIS USA XX-Large Side Entry Litter Box — Biggest Amazon Option

If you don’t shop at Chewy, this is the closest Amazon equivalent — and it’s bigger. The IRIS USA XX-Large measures 30″ x 20″ x 14″ with tall 14-inch walls and a 6.5-inch curved side entrance, explicitly built for large breeds (Maine Coons, Ragdolls) and multi-cat households. The smooth interior with minimal crevices is designed for easy wipe-downs, and the open top keeps airflow moving and scooping easy. It’s a top-10 best seller in Amazon’s Standard Cat Litter Boxes category.

Trade-offs: at 30 inches long it’s even more of a space commitment than the Frisco — this is a piece of furniture, so measure twice. It’s also a newer listing (late 2025), so its review history is shorter than the Frisco’s years-long track record. And like the Frisco, open-top means odor isn’t contained.

Specs: 30″ L x 20″ W x 14″ H · 14″ high walls · 6.5″ curved side entrance · open top · smooth easy-clean interior.

Pros: the largest high-sided option here; 14-inch walls beat the Frisco on height; made for big breeds and multi-cat homes; easy-clean design.

Cons: huge footprint — the biggest space commitment on this list; shorter review history than Frisco; open top doesn’t trap odor.

Verdict: The Amazon answer to the Frisco — bigger walls, bigger footprint. Check the price on Amazon.

4. EGMEHOAD Stainless Steel Litter Box (2-Pack) — Best Stainless 2-Pack

The upgrade path from plastic: two XL stainless steel boxes (23.6″ x 15.7″ x 12″) with 12-inch high sides, wrapped corners, and a leak-proof overlap design. Stainless doesn’t absorb odor or stain the way plastic eventually does, the non-stick surface wipes clean, and the brand claims a multi-year lifespan versus replacing plastic pans. Each box comes with a lid option, mat, and scoop — and you get two boxes, which is the actual recommended number for one cat anyway.

The honest caveats: stainless boxes cost multiples of a plastic pan, the 12-inch walls with the enclosure make it a less open feel that some cats reject, and the included accessories (mats, scoops) are budget-grade. Also note the “lid” here is a high-wall enclosure rather than a true covered top — odor still escapes upward.

Specs: 2-pack · each 23.6″ x 15.7″ x 12″ (27L capacity) · 12″ high sides · stainless steel pan with enclosure · includes mat and scoop.

Pros: stainless doesn’t retain odor or stain; non-stick and easy to clean; two boxes covers the one-cat recommendation; 12-inch walls.

Cons: costs far more than plastic; some cats dislike the enclosed feel; included accessories are basic; not a true covered top.

Verdict: The long-term upgrade — pay more once instead of replacing plastic pans. Check the price on Amazon.

5. Vivifying Stainless Steel XL Side Entry — Best Enclosed Option

Vivifying’s XL stainless box (23.6″ x 15.7″ x 15.55″) offers something the others don’t: three configurations — fully enclosed for maximum odor control, open-door for transitioning cats, and semi-enclosed for airflow. The 5.9-inch walls plus a 3.75-inch top shield give double protection against scatter, and the stainless pan resists rust, scratches, and odor absorption. It includes a scoop, honeycomb mat, footboard for kittens/seniors, and anti-slip pads.

Watch-outs: it’s rated for cats up to about 16 lbs, so very large breeds should look at the IRIS instead. The modular enclosed design has more parts to clean than a simple open pan, and as with all stainless options, you’re paying a premium over plastic.

Specs: 23.6″ x 15.7″ x 15.55″ · 5.9″ sides + 3.75″ top shield · three configurations (enclosed/open/semi) · stainless steel · cats up to ~16 lbs · includes mat, scoop, footboard.

Pros: only enclosed option here — best odor containment; convertible configurations; stainless durability; senior/kitten footboard included.

Cons: ~16-lb cat limit excludes giants; more parts to clean; premium price.

Verdict: The odor-control pick — the only one that closes. Check the price on Amazon.

6. Henkelion Stainless Steel Litter Box (2-Pack) — Budget Stainless

The value entry into stainless: a 2-pack of 20″ x 14.2″ x 11.8″ boxes (26L capacity) with high-sided ABS enclosures, overlap anti-leak design, and the standard accessory bundle — double-layer mat, scoop with holder, anti-slip pads. Same core pitch as the EGMEHOAD: stainless pan that won’t absorb odor, easy wipe cleaning, longer lifespan than plastic.

The compromises at this price: it’s the smallest box on this list — fine for average cats but tight for large breeds — and the enclosure plastic is the budget part of the package. Set expectations accordingly: the pan is the upgrade, the accessories are adequate.

Specs: 2-pack · each 20″ L x 14.2″ W x 11.8″ H (26L) · stainless pan + high-sided enclosure · includes mat, scoop, anti-slip pads.

Pros: cheapest path to stainless; two boxes; anti-leak overlap design; easy-clean pan.

Cons: smallest footprint here — not for large breeds; enclosure plastic is budget-grade.

Verdict: The budget stainless — the pan is the point. Check the price on Amazon.

How to Choose a High-Sided Litter Box

Measure your space before you buy. The Frisco XL is 24″ x 18″ and the IRIS XXL is 30″ x 20″ — both are bigger than they look in photos, and “my fault for not measuring” is a real owner quote. Tape out the footprint on the floor where the box will live.

Match wall height to the crime. Enthusiastic diggers need tall walls all around (10+ inches); stand-up peers need height specifically at the back and sides. A 5–6 inch entry keeps it accessible — but remember the entry is also where litter escapes, so plan on a mat regardless.

Open top vs. enclosed is an odor decision. Open-top high-sided boxes (Frisco, IRIS) win on airflow and easy scooping but do nothing to trap smell. If the box lives in a small room, the enclosed Vivifying contains odor far better — at the cost of more parts to clean.

Plastic vs. stainless is a longevity decision. Plastic pans are cheap and light but eventually absorb odor and need replacing; stainless costs more up front and wipes clean for years. If you’re buying your third plastic box, do the math on stainless.

Count the litter. Bigger boxes need more litter to reach a proper 3–4 inch depth — the Frisco XL’s larger area noticeably increases fill volume. Budget for it, especially with multi-box households.

Travel note: a high-sided box is actually the good travel litter box — the tall walls contain scatter in a moving car or RV far better than a standard pan. For trips, pair a smaller high-sided box with a lidded storage tote for the litter supply.

Bottom line: the Frisco High Sided (XL, 24-in) is the best value in high-sided boxes — if you shop at Chewy. If you want it on Amazon, the IRIS USA XX-Large is the closest (and larger) equivalent; the EGMEHOAD stainless 2-pack is the long-term upgrade; and the Vivifying is the pick when odor containment matters most.

Frequently Asked Questions

Is the Frisco High Sided Cat Litter Box good?

Yes, by the numbers: roughly 4.8 stars across 7,000+ Chewy ratings, with strong marks for containing diggers and high-peering cats. The main criticisms are its large footprint, the amount of litter it takes to fill, and that the open top doesn’t trap odor. It’s the default recommendation for scatter problems at a budget price.

Where can I buy the Frisco High Sided Litter Box?

Only at Chewy — Frisco is Chewy’s exclusive house brand, so there’s no Amazon listing. If you don’t shop at Chewy, the IRIS USA XX-Large Side Entry box is the closest Amazon-available equivalent with even taller walls.

What are the dimensions of the Frisco High Sided Litter Box?

The Extra Large (24-in) measures 24″ long x 18″ wide x 10″ high, with a lowered front entry of about 5.6 inches. Measure your space before ordering — it’s bigger than it looks in product photos.

Will a high-sided box stop litter tracking?

It reduces it substantially but won’t eliminate it. The tall walls contain the flinging and spraying; the low entry — the part cats actually walk through — still lets litter out on paws. Pair any high-sided box with a litter mat for the complete solution.

Are high-sided boxes good for kittens and senior cats?

Yes, provided the entry is low. The Frisco’s 5.6-inch entry and the IRIS’s 6.5-inch curved entrance are both step-over-able for kittens and arthritic seniors — that’s the whole point of the cut-down front wall. True top-entry boxes are the ones to avoid for limited-mobility cats.

How do you clean a high-sided litter box?

Scoop daily like any box, but add a quick wipe of the tall interior walls — urine can cling and leave residue, especially with dusty litters. The smooth, crevice-free interiors of the Frisco and IRIS make this a ten-second job with a damp cloth or a vinegar-water spray.
