The Best Litter Boxes for Senior Cats

The best senior cat litter box has a low entry an older cat can step over without lifting its back legs high, a pan big enough to turn around in, and sides tall enough at the back to hold in litter. For a cat with stiff hips or weak hind legs, entry height matters more than any other feature, so this list gives the listed entry height for every pick where the maker publishes it.

Our picks draw on published specifications, independent reviews, and Amazon owner ratings. They range from 2.7-inch stainless steel pans to plastic boxes with a low front and a taller back.

This guide is general product information, not veterinary advice. If your cat’s litter box habits change, such as straining, going outside the box, or producing much more or less urine than usual, contact your veterinarian.

How to Choose a Senior Cat Litter Box

Start With the Entry Height

Watch how your cat steps into its current box. If it hesitates, perches on the rim, or goes just outside the pan, the entry is likely too high. These are the entry heights the makers list:

• Ixaro stainless steel: 2.7 inches
• Amibud stainless steel: 2.76 inches (the whole pan is this tall)
• TAILRYTH extra large: 2.9 inches, at an angled corner entry
• KittyGoHere and KittyGoHere 2.0: 3 inches
• Qiuma stainless steel: 3.15 inches
• LoopTime high sides: 4.5 inches

The SpaceTime and BOHESI boxes are sold as low entry but do not list an exact height, so measure them against your cat when they arrive.

Low Front, Taller Back

A low entry makes getting in easier, but a pan that is low all around lets litter fly out. The better senior designs keep the front low and the back and sides higher. Qiuma pairs a 3.15-inch entry with raised sides and back, Ixaro keeps 5.9-inch walls around a 2.7-inch entry, and KittyGoHere 2.0 adds a higher back and sides. The Amibud pan is only 2.76 inches tall everywhere, which is easiest to enter but holds in the least litter.

Size for a Stiff, Older Cat

A common rule of thumb is a box about one and a half times your cat’s length from nose to the base of the tail. Older cats that cannot crouch well often stand or shift around more, so extra length helps. The KittyGoHere is listed at 24 by 20 inches and the TAILRYTH at 23.6 by 15.7 inches, while the Amibud and the Qiuma size on this listing are about 17.5 by 13.6 inches, better for small cats. Qiuma and Ixaro sell larger sizes too.

Stainless Steel or Plastic

Stainless steel pans from Qiuma, Ixaro, and Amibud resist the scratches that let plastic hold odor over time; see our stainless steel litter box picks. Plastic pans like the KittyGoHere, LoopTime, and TAILRYTH are lighter and come in larger sizes with shaped walls, which matters if you lift and rinse the box yourself.

Placement Matters as Much as the Box

Put a box on every floor your senior cat uses, so it never has to climb stairs in a hurry. A night light helps a cat with weaker eyesight find the box after dark, and a non-slip mat under a light plastic pan keeps it from sliding. In a home with more than one cat, a common rule of thumb is one box per cat plus one extra.

Who Should Look Elsewhere

If your cat cannot step over even a 3-inch edge, a shallow tray with a puppy pad or a box with a ramp may work better than any pan here. If your cat sprays high or kicks hard, a low-entry box with tall sides from our high-sided litter box picks or a hooded box from our covered litter box picks may suit it, as long as the entry stays low. For all styles, see our best litter box picks.

A senior cat that suddenly stops using the box, strains, makes many trips with little urine, or has blood in the urine needs a call to your veterinarian the same day. Pain and illness can look like a box problem, so rule them out before changing boxes.

Why You Should Trust Us

IndoorCatLab reviews gear for indoor cats independently. We do not conduct our own product trials; our picks draw on published specifications, independent reviews, and Amazon owner ratings, which also set each product’s ICL Score.

The ICL Score converts each product’s average Amazon owner rating to one 0 to 10 scale. Our ranking also weighs entry height, pan size, and wall design, so the order of the list is not the same as sorting by score. We may earn a commission from qualifying purchases, but that never affects a product’s ranking or score. Read the full method in How We Review.

Frequently Asked Questions

How low should a senior cat litter box entry be?

Low enough that your cat steps in without hesitating. The picks here range from 2.7 to 4.5 inches; for a cat with stiff hips, start at the lower end.

Is a low entry litter box good for kittens too?

Yes. Several makers here list their pans for kittens as well as seniors. Choose a smaller pan for a kitten and size up as it grows.

Can a senior cat use a covered litter box?

Some can, if the entrance is low and the inside is roomy. Many older cats prefer an open top, which is easier to step into and lets them see around them.

Why has my senior cat stopped using the litter box?

Call your veterinarian first, since pain or illness can be the cause. Then check the box: an entry that is too high, a box that is too far away, or litter that is not clean enough are common reasons.
