Choosing the Best Low-Entry Litter Box for Senior Cats

By Mittens Whiskerton · Last updated October 25, 2026

The short answer

A low-entry litter box for senior cats is the single cheapest change that fixes most accidents. Look for an entry two to three inches high, an open top, a box long enough for your cat to turn around in, and a smooth lip they can step over without catching a paw.

Why we like it: A box with a low, scooped entrance is the single easiest change for an older cat who can no longer hop over a high rim, and it is simple to scoop from the side.

Why the box becomes the problem

A cat with stiff hips has to lift a hind leg over the rim every single time. Many will do it for a while, then start going just outside instead, which reads as behaviour but is usually pain or effort avoidance. The fix is rarely a new diet or a new routine. It is a lower wall.

What to look for

An entry around two to three inches high, measured from the floor, and a box at least one and a half times the length of your cat so they can turn around comfortably. An open top lets them watch the room and keeps odour from building up.

How to make the switch

Put the new box beside the old one rather than replacing it outright, and move a handful of used litter across so the scent is familiar. Once your cat is using the new box reliably for a week, remove the old one.

Pros

Easy for a stiff cat to step into instead of over.
Simple to scoop from the side with a full view of the box.
Lets your cat see the room while they go.
Cheap and widely available.

Cons

Less odour control than a covered box, so scoop more often.
Litter can scatter further without a high wall.
Some cats still prefer a covered box they have used for years.

How to set this up

01Place the new low box directly beside the old one.
02Add a thin layer of unscented litter, about an inch deep.
03Move a scoop of used litter across so the smell is familiar.
04Add a soft night light on the route to the box.
05Remove the old box once your cat has used the new one for a week.
