Best Cat Litter Boxes 2026: Less Tracking, Less Smell
Most litter box complaints are really placement and size complaints wearing a costume. Cats want a box that is at least one and a half times their body length, in a spot with two exits, and cleaned more often than the marketing on the bag implies.
Get those right and the box you choose matters less. Get them wrong and no amount of odour-locking plastic saves you. Below are the boxes worth buying once you have the basics sorted, including the ones that solve tracking, spraying over the edge, and stiff old cats who cannot climb.
What is in this guide
Quick verdict
- Best overall: IRIS large box with a scatter shield
- Best against tracking: Modkat XL top-entry
- Best for senior cats: KittyGoHere low-entry box
Size and count, the two rules that matter
The standard veterinary guidance is one box per cat plus one, and a box length of at least 1.5 times the cat from nose to tail base. A 16 inch cat wants a 24 inch box. Most boxes sold as large are 22 inches, which is why big cats hang over the edge and pee on your floor.
| Cat | Minimum box length | Typical product size | Notes |
|---|---|---|---|
| Small adult, under 10 lb | 20 inches | Standard | Most boxes fit |
| Average adult, 10 to 14 lb | 24 inches | Large | Look for jumbo labelling |
| Maine Coon or 15 lb plus | 28 inches | Rare | Consider a storage tote |
| Senior or arthritic | Any length, under 4 inch entry | Low entry | Height matters more than length |
The cheapest upgrade in cat ownership is a 28 inch plastic storage tote with a doorway cut in one end. It costs under $20 and outperforms most purpose-built boxes for large cats. If aesthetics matter, the picks below are the next best thing.
The best cat litter boxes in 2026
IRIS Large Cat Litter Box with Scatter Shield
Best overall
- Type: Open with high sides
- Entry: Low front step
- Extras: Scatter shield, scoop hook
High walls with a cut-down entry is the combination that solves the most problems at once. Cats who spray upward are contained, cats with stiff hips still get in, and there is no hood to trap smell against your cat face.
The scatter shield clips on and off, which matters because the parts people never remove are the parts that never get washed.
Pros
- High sides stop over-the-edge spraying
- Low entry works for older cats
- No hood, so most cats accept it immediately
- Easy to hose out
Cons
- Litter still tracks from paws
- Plain looking

Modkat XL Top-Entry Litter Box
Best against tracking
- Type: Top entry
- Lid: Reusable liner and swivel lid
- Footprint: Compact
Top entry is the single most effective anti-tracking design, because the cat has to step onto a grated lid on the way out and most of the litter falls back in. If your problem is grit across the hallway, this fixes it more than any mat.
The catch is that top entry does not suit every cat. Kittens, seniors and overweight cats often refuse it, and a cat that refuses a box will find your rug.
Pros
- Dramatically less tracked litter
- Small floor footprint
- Contains smell without a full hood
Cons
- Wrong choice for arthritic or very young cats
- Expensive for a plastic box
KittyGoHere Senior Cat Litter Box
Best for senior cats
- Entry height: About 3 inches
- Type: Open
- Use: Seniors, kittens, disabled cats
Arthritis in cats is under-diagnosed and shows up as house soiling long before it shows up as limping. If a previously reliable cat starts missing the box after age ten, entry height is the first thing to change.
This box is unglamorous and it works. Three inch entry, no lip to catch a stiff hock.
Pros
- Solves most senior-cat accidents on its own
- Also good for kittens and post-surgery cats
Cons
- Low sides mean more scatter
- Not for cats who spray high
Frisco Multi-Function Covered Litter Box
Best covered box
- Type: Covered, removable lid
- Door: Optional flap
- Size: Large
If you want a hood for appearance or for a dog that raids the box, buy one where the lid comes off in one movement and the flap is optional. Covered boxes need more frequent scooping, not less, because the smell concentrates inside where the cat is.
Take the flap off for the first two weeks so the cat learns the box without pushing through a door.
Pros
- Keeps dogs and toddlers out
- Lid lifts off cleanly for scooping
- Looks tidier in a living space
Cons
- Needs scooping twice daily to stay pleasant
- Some cats never accept a hood

Tidy Cats Breeze Litter Box System
Best low-dust system
- Type: Pellet and pad system
- Litter: Proprietary pellets
- Best for: Dust-sensitive homes
The pellet-and-pad approach separates solids from urine and produces almost no dust, which matters in homes with asthma or with a cat that has had respiratory problems.
Ongoing cost is the trade. Pads and pellets are a subscription in practice, and switching a cat over takes a gradual mix over two weeks.
Pros
- Almost no dust and very little tracking
- Urine odour handled by pads rather than clumping
Cons
- Ongoing consumable cost
- Some cats dislike pellet texture
Placement mistakes that cause accidents
- Do not put the box next to the food and water. Cats will not eat next to a toilet either.
- Avoid corridors and cupboards with one exit. A cat that feels cornered stops using the box.
- Never place it next to a washing machine or furnace that cycles loudly.
- In a multi-cat home, spread boxes across floors rather than lining them up in one room.
If a cat suddenly stops using a box it has used for years, that is a vet visit before it is a shopping problem. Urinary blockage in male cats is an emergency, and litter box avoidance is often the only early sign.
Litter box FAQ
How many litter boxes do I need for two cats?
Three, placed in different rooms. The plus-one rule exists because one cat guarding a box in a shared space is a common cause of accidents.
How deep should the litter be?
Two to three inches for clumping litter. Deeper wastes litter and does not improve odour control; shallower lets urine reach the plastic and stain it.
How often should I scoop?
Twice a day is what keeps a box genuinely acceptable to a cat. Full changes every two to four weeks for clumping litter, weekly for non-clumping.
Do covered boxes trap odour?
They trap it from you and concentrate it for the cat. If you use a hood, scoop more often, not less.
Will a top-entry box stop tracking completely?
No, but it cuts it more than any mat or high-sided open box. Expect a large reduction rather than elimination.
Is an automatic box worth it?
Only if you commit to the maintenance. They fail in two ways people underestimate: sensor errors with lightweight cats, and mechanisms that clog with cheap clumping litter.
Which litter box should you buy?
Final verdict
Buy the IRIS large box unless you have a specific problem. If that problem is grit across the house, buy the Modkat XL. If it is an older cat missing the box, buy the KittyGoHere and change nothing else first.
