Best Cat Litter Boxes in 2026
By PetReviewLab Editors
Updated April 2026
CAT
Cats are particular about their litter boxes. A box that is too small, too enclosed, or too hard to clean gets abandoned — and your cat finds somewhere else to go. Most litter box problems are solved by getting the right box and keeping it clean.
We tested standard, hooded, top-entry, and self-cleaning options. Here is what we recommend.
Best Overall
Nature's Miracle Oval Hooded Litter Box
★★★★★
Nature's Miracle's hooded box has an antimicrobial plastic treatment baked in that actually helps with odor between cleanings. The oval shape is large enough for most cats to turn around comfortably. The hood has a carbon filter that absorbs ammonia smell. The swinging door keeps litter from scattering. It is one of the easiest boxes to keep clean thanks to the wide hood opening that comes fully off for scooping.
Pros
- Antimicrobial plastic treatment
- Carbon filter in hood
- Wide hood removes fully for cleaning
- Large enough for most cats
Cons
- Some large cats feel cramped
- Door can discourage shy cats
Best Top-Entry
Modkat Top-Entry Litter Box
★★★★★
Top-entry litter boxes are the best solution for cats that kick litter out of standard boxes. The Modkat has cats enter from the top, do their business, and exit — and most litter falls back in when they jump out. The lid has a textured mat that catches any litter stuck to paws. The polished design looks far better than any standard litter box. Cats with mobility issues cannot use top-entry boxes, but for healthy adult cats it is the cleanest option.
Pros
- Nearly eliminates litter scatter
- Lid mat catches paw litter
- Very clean modern design
- Sturdy plastic
Cons
- Not suitable for elderly or mobility-impaired cats
- Some cats dislike top entry initially
Best Budget
Van Ness Extra Large Covered Cat Litter Box
★★★★
The Van Ness extra large hooded box is the budget option that gets the basics right. It is genuinely large enough for big cats (24 inches long), the hood lifts off easily for full cleaning access, and the plastic is thick enough to not crack easily. No carbon filter, no antimicrobial treatment, but at its price point it is a solid functional litter box that will last years.
Pros
- Very affordable
- Genuinely extra large size
- Easy to clean
- Durable plastic
Cons
- No carbon filter
- Basic design — no extra features
- No door on opening
How many litter boxes do you need
The standard rule is one litter box per cat plus one extra. For a single cat, two boxes. For two cats, three boxes. This prevents one cat from monopolizing all access and gives cats options if one box is recently used. In multi-level homes, at least one box per floor is important — cats sometimes will not travel between floors to find a clean box.
Open vs covered litter boxes
Covered boxes reduce scatter and contain odor for humans. However, they trap odor inside the box where the cat has to breathe it — which some cats dislike. If your cat is avoiding a covered box, remove the hood and see if behavior improves. Very large cats may also dislike the cramped space. In general, offer a mix and let your cat tell you what they prefer.
Frequently Asked Questions
How often should a litter box be fully cleaned?
Scoop at minimum once daily — ideally twice. A full dump, wash with soap, and refill should happen every 2 to 4 weeks depending on how many cats use it. Plastic absorbs ammonia over time, so even a clean-looking box can smell. Replace the box itself every 1 to 2 years.
Why is my cat avoiding the litter box?
Common reasons: not scooped frequently enough, litter brand changed, box too small, box too enclosed, new pet or person in the house stressing the cat, or a medical issue like a UTI or crystals. If a cat that has been reliably using the box suddenly stops, a vet visit is warranted.
Bottom Line
Nature's Miracle's hooded box is the best everyday option for most households, combining odor control with ease of cleaning. The Modkat top-entry box is the best solution if litter scatter is your main problem. The Van Ness covers the basics at a price that makes the two-box rule easy to follow on a budget.
