Quick answer. The OneBug High-Sided Stainless Steel XL Cat Litter Box is the top pick in this list, because it is the only listing that states a wall height: 10.04 inches. Its listed product dimensions are 22.83 by 14.96 inches. Each size below is the seller’s listed size, not a measurement we took. If you want a lid, the FZGhome flip-lid box and the BlissBlaze XXXXL box both have one, and they are larger. The Amazon Basics and IRIS USA boxes are open-top, but their listings do not state a wall height.
How we chose
We opened five Amazon listings on 2026-10-17 and used only what each listing states. The criteria:
- Side height: a wall height stated in the listing. Most listings give only an overall height.
- Lid or open top, as the listing describes it.
- Listed size, so you can check it against your floor space.
- Material and listed weight.
Many of these listings call a box “high-sided” in the title. We quote the title, then check the listing for a height. Where the listing gives none, we say so.
Comparison table (as stated on each listing, checked 2026-10-17)
| Product | Listed size (in) | Listed weight (product field) | Lid | Wall height stated |
|---|---|---|---|---|
| Amazon Basics Large Cat Litter Box, High Sides, Open Top | 19 x 15 x 11.75 | 1.95 lb | No (open top) | Not stated |
| IRIS USA High Sided Cat Litter Box, Large, Scatter Shield | 19 x 15 x 11.75 | 1.96 lb | No (open top) | Not stated |
| FZGhome Stainless Steel Litter Box with Flip Lid, XL | 23.62 x 15.75 x 15.35 | 7.63 lb | Yes, flip lid | Not stated; overall height 15.35 |
| OneBug High-Sided Stainless Steel XL Cat Litter Box | 22.83 x 14.96 x 10.24 | 5.47 lb | Not stated | 10.04 inches |
| BlissBlaze XXXXL Stainless Steel Litter Box with Lid | 28 x 20 x 17 | 11.02 lb | Yes | Not stated; overall height 17 |
The size and weight columns use the product-details fields. The listings do not say whether those fields describe the box or its packaging.
Worked example: will it fit a 24-inch floor space?
Suppose you have 24 inches of floor along one wall. Subtract each listed length from 24. The OneBug field length of 22.83 inches leaves 1.17 inches. The BlissBlaze length of 28 inches does not fit at all. The OneBug’s interior measurement in its text is 22.95 inches, so the fit is tight in either case. Leave room for the cat to turn and for you to reach the scoop.
Products
1. OneBug High-Sided Stainless Steel XL Cat Litter Box (top pick)
Best for: owners who want a stated wall height. The listing says the 10.04 inch walls help keep litter and urine inside the box.
Skip if: you need a lid, because the title does not mention one, or if your floor space is under about 23 inches long.
Listing specs (checked 2026-10-17): product dimensions 22.83 x 14.96 x 10.24 inches; 5.47 pounds; model XC-MSP-T181-Gray; manufacturer OneBug; first available April 16, 2026. The About this item text gives 22.95 x 14.80 x 10.04 inches and says the listing may vary by 0.1 to 0.3 inches from manual measurement. The listing mentions a built-in anti-tracking step. We did not verify that claim.
2. FZGhome Stainless Steel Litter Box with Flip Lid, XL
Best for: a larger box with a lid. The listing says the high sides and overlapping structure help prevent urine leaks and splashes, and that the set includes a mat, handle, pedal and scoop.
Skip if: your floor space is under about 24 inches long, or you need a wall height the listing states. It gives an overall height of 15.35 inches, not a wall height.
Listing specs (checked 2026-10-17): dimensions 23.62 x 15.75 x 15.35 inches; 7.63 pounds; model T166; brand FZGhome; material stainless steel; first available May 5, 2026. The listing gives a capacity of 30 liters or more.
3. BlissBlaze XXXXL Stainless Steel Litter Box with Lid
Best for: large cats or more than one cat. The listing gives the box as 28 x 20 x 17 inches, and it includes a scoop and a built-in scratching pad.
Skip if: your floor space is smaller than 28 inches, or you do not want a scratching pad on the box. The listing describes it as a 3-in-1 box.
Listing specs (checked 2026-10-17): dimensions 28 x 20 x 17 inches; 11.02 pounds; model XM-B1; brand BlissBlaze; first available April 28, 2026. The title says it has a lid, a cat scratcher and a scoop.
4. Amazon Basics Large Cat Litter Box with High Sides, Open Top
Best for: an open top for easy monitoring and scooping. The listing says the open design lets you see the litter and the scoop is stored on the box.
Skip if: you want a wall height. The title says high sides, but the listing does not state the height. The same listing also says the front is lowered for easy entry, so the sides are not high all the way around.
Listing specs (checked 2026-10-17): dimensions 19 x 15 x 11.75 inches; 1.95 pounds; open top; grey and beige; BPA-free, recyclable plastic; includes a scoop with onboard storage.
5. IRIS USA High Sided Cat Litter Box, Large, Scatter Shield
Best for: an open-top box in black with a listed 19 by 15 inch footprint. The title names a scatter shield.
Skip if: you need a wall height, because the listing does not state one. Skip it also if you want a lid.
Listing specs (checked 2026-10-17): dimensions 19 x 15 x 11.75 inches; 1.96 pounds; model 500452; manufacturer IRIS USA; color black; first available July 13, 2016. The listing describes an open top that gives cats plenty of room.
Listing conflicts we did not resolve
- OneBug: the product-dimension field (22.83 x 14.96 x 10.24) differs from the About this item measurements (22.95 x 14.80 x 10.04). The listing says the difference may be 0.1 to 0.3 inches.
- Amazon Basics: the title says high sides, and the bullet says the front is lowered for easy entry.
- FZGhome: the title says XL, and a bullet says XXXL size. Check the dimensions on the page.
Mistakes to avoid
- Reading “high sides” in a title as a height. Check whether the listing gives one.
- Buying the biggest box for a small room. The 28-inch box needs far more floor than the 19-inch boxes.
- Trusting the dimension field alone. Two listings here give an interior size that differs from the field.
Who should skip buying from this list
Skip this list if you need a documented wall height for every box, or if your floor space is under about 19 inches. If your cat changes how it uses the box, strains to pass urine, or goes outside the box, ask a vet. A box cannot answer a health question.
FAQ
How high are the sides on these boxes?
Only the OneBug listing states a wall height, at 10.04 inches. The other listings give an overall height in their dimension fields, or no height at all.
Do the high sides stop leaks and splashes?
The FZGhome and OneBug listings say their high sides help prevent leaks, splashes or scatter. We did not check those claims. Plan to scoop and clean the floor under the box.
Open top or lid?
The Amazon Basics and IRIS listings are open top. The FZGhome and BlissBlaze boxes have lids. The listings do not compare odor or privacy between the two types, so choose based on your cat and your room.
How big should the box be?
The FZGhome listing says the box should let cats of almost all sizes turn around. Measure your floor space and your cat before you choose. The OneBug field length of 22.83 inches is the smallest footprint in this list that states a wall height.
