How to Get a Cat to Use the Litter Box
A cat going outside the box is not being spiteful. It is reporting a problem, and the list of things it could be is short.

Everyone in this category says they tested twenty litter boxes. We have not tested any, and we say so. What we do instead: compile the published specs, read the manuals, and do the arithmetic on what this gear costs to run and how it behaves once there is more than one cat using it. Every spec is linked to the document it came from. Prices are checked daily — last verified September 25, 2026. Here is exactly how we pick.
There is a running order for this problem, and starting at the wrong end of it is how people spend two months and a lot of money without fixing anything.
One: the vet
The Cornell Feline Health Center lists urinating outside the litter box among the signs of feline lower urinary tract disease. Straining, frequent small visits, blood, or crying in the box all point the same way, and a male cat that cannot urinate is an emergency.
Book the appointment before you buy anything. Everything below assumes a vet has ruled out a medical cause, or is treating one.
Two: can the cat still get in?
This is the cause people miss most, because the box has not changed -- the cat has. A wall that was nothing at three years old is a hind-leg lift twice a day at fourteen.
A box with a 3 inch cut-down entry removes the problem entirely, and it is the first thing we would change for any cat over about ten. Our senior box page covers the entry heights across the category.
Three and four: the litter, and how clean it is
- Texture. Fine-grained and unscented is the published preference. Dr. Elsey’s Ultra matches it, and switching back to a plain clay litter is a cheap test.
- Depth. About two inches. Too shallow and the cat feels the pan; too deep and it wades.
- Scooping. Daily, twice in a multi-cat home. A cat will hold on rather than use a dirty box, and then go somewhere else when it cannot hold on any longer.
- Washing. Weekly with mild detergent. If a plastic pan smells even after washing, it is scratched and it is time to replace it.
Five and six: where it is, and how many
A box in a dead end, beside a washing machine, or next to the food is a box a cat has reasons to avoid -- our placement page covers the rules. And the count is not a style choice: one per cat plus one, spread around the house rather than lined up in one room, as our box count page explains.
A plain jumbo pan is the cheapest way to add boxes while you work out which change did it. Big, open, no hood to push through, and cheap enough to buy two.
Working the list
- Vet first. Always.
- Add a box, somewhere new, with the cat’s usual litter.
- Lower the entry, or offer a low-entry box alongside the current one.
- Go back to plain, unscented, fine-grained litter.
- Scoop twice a day for a fortnight, whatever your usual routine.
- Clean every accident with an enzyme cleaner so the spot stops advertising itself.

KittyGoHere Senior Cat Litter Box
KittyGoHere · Low-entry litter box · Our score 8.0/10
#ad Price as of September 25, 2026. Prices move; we check daily. How we're funded.
A published 3 inch entry against the 6 to 8 inches a standard pan asks for, which is the difference between a box an arthritic cat uses and one it gives up on.
Published specs
| Large | 24" x 20" x 5", cats up to 20 lb |
|---|---|
| Small | 20" x 15" x 5", cats up to 6 lb |
| Jumbo | 28" x 22" x 9", 3" opening |
| Entry height | 3" |
| Form | Open top, low cut-down entrance |
| Made in | USA |
A standard high-sided pan asks a cat to lift a hind leg 6 to 8 inches. This publishes 3. For a cat with stiff hips that is not a comfort improvement, it is the difference between clearing the wall and standing in the doorway to go.
What the specs favor
- Publishes an entry height, which almost no litter box does
- Large size gives 480 square inches of floor, more than most covered boxes
- Open top, so no door, no hood and no single choke point
- Three published sizes with cat-weight guidance on two of them
What they don't
- Low walls mean a high-spraying cat will go over them
- Open design contains no odor at all
- Litter scatters more than from a high-sided pan
Your cat sprays upward or digs enthusiastically. Five inches of wall is not enough, and the answer for that cat is the opposite box.

Petmate Jumbo Litter Pan

#ad Price as of September 25, 2026. Prices move; we check daily. How we're funded.
The plain plastic pan that lets you follow the one-box-per-cat-plus-one rule without spending like it.
Published specs
| External dimensions | 22.05" x 16.55" x 6.5" |
|---|---|
| Wall height | 6.5" |
| Type | Open pan, no cover |
| Litter type | Any |

Cornell's guidance is one box more than you have cats. For three cats that is four boxes. The cheapest automatic box on this page is $269.99 -- four plain jumbo pans is a fraction of one of those, and four boxes beat one clever one every time.
What the specs favor
- Cheap enough to buy four without thinking about it
- 22 inches long, which is genuinely jumbo for a plain pan
- Open, uncovered, low -- the configuration cats prefer
- Nothing to break, nothing proprietary
What they don't
- 6.5-inch walls will not contain a cat that sprays standing up
- No scatter shield at all
- Thin plastic scratches, and scratched plastic holds odor
Odor or scatter is your actual complaint. This pan solves the count problem, not the containment problem -- pair it with a high-sided box rather than replacing one.

Dr. Elsey's Ultra Unscented Clumping Clay Litter
Dr. Elsey's · Cat litter · Our score 8.8/10
#ad Price as of September 25, 2026. Prices move; we check daily. How we're funded.
Unscented, medium-grain, 99.9 percent dust-free -- which is the exact specification the veterinary guidance on litter preference describes, rather than a marketing claim.
Published specs
| Material | Natural clay |
|---|---|
| Scent | None; no perfumes or deodorants |
| Dust | 99.9 percent dust-free (Dr. Elsey's) |
| Grain | Medium grain with heavier non-tracking granules |
| Bag size | 40 lb |
| Additives | Free of plant proteins, perfumes and deodorants |

The Ohio State Indoor Pet Initiative says most cats prefer fine-grained, unscented litter and are deterred by scented or deodorant products. This litter is unscented, deodorant-free and fine-to-medium grain -- it meets all three published criteria. Very few litters marketed for odor control do.
What the specs favor
- Unscented and deodorant-free, matching the documented feline preference
- 99.9 percent dust-free by the maker's own measure
- Heavier granules specifically to reduce tracking
- Hard clumping, so waste leaves the box intact
What they don't
- Clay, so it is heavy to carry and heavy to lift out
- No added fragrance means it does nothing to mask odor between scoops
- 40 lb bag is awkward to store in a flat
You want the litter to do the odor work for you. This one is deliberately inert -- it relies on you scooping daily, which is what the veterinary guidance asks for anyway.
