Best Low Entry Litter Box for Senior Cats (2026)

The best low entry litter box for a senior cat has an entrance low enough to step through and is long enough for the cat. AAHA and AAFP say box edges should not be too high for a senior cat to enter and exit easily, and recommend a box at least 1.5 times the cat’s length.

Only one of the four boxes below publishes an entry height as a number, so the table says “Not published” wherever a figure is missing instead of guessing. International Cat Care says open trays with low sides are ideal for older cats, but that trial and error will help you find your cat’s preference.

Specs are each maker's published figures from its own page, checked 26 October 2026. “Not published” means the maker's page text does not state that figure; it does not mean the box lacks one. The Jumbo's 5 in is the entrance with its removable gate. Feandrea and PetFusion sizes are length × width × height; their 11.8 in and 8 in are overall heights, not the entry. Kitty Sift's size is its Large sifting liner (width × length × height) from its FAQ page, and its high shield lid adds about 1 in at the entryway. Links marked “Check price” are affiliate links.

Published 3 in entry: KittyGoHere Jumbo Cat Litter Box

KittyGoHere’s Jumbo page lists a 3 in entrance and cats up to 35 lb, the highest weight guide here. A removable gate changes the entrance height from 3 to 5 in. The box is polypropylene that wipes clean with soap and water, with a reinforced bottom that, the maker says, keeps it from warping and makes it easier to lift, even with the weight of litter.

Stainless steel, open top: Feandrea UPPT008

Feandrea’s page (SKU UPPT008GN01, Slate Gray) gives the size as 24.4 in L × 16.5 in W × 11.8 in H and says the box has room for cats up to 33 lb, with a low front entrance and a gently sloped step. The materials are stainless steel and polypropylene, and the product weight is 5.8 lb. At 24.4 in it is the longest box here.

Large open pan: PetFusion BetterBox

Petmate’s PetFusion BetterBox page (SKU PF-LB1A-S, gray, single box) gives the size as 22.6 in L × 18.1 in W × 8 in H. It is made of ABS plastic with a non-stick coating, has an easy-grip lip and spacious curved sides, and the maker lists it for clumping, pellet, lightweight and crystal litter. The page describes a “low entry” but gives no height for it.

Stacked liners: Kitty Sift Large

Kitty Sift’s FAQ page gives the Large sifting liners as 14 in wide × 18 in long × 4 in high and the Jumbo liners as 17.25 × 20.5 × 5.25 in. Stacked in 4, 8 or 12 layers, the liners are slightly taller, depending on how many layers are added. The high shield lid adds approximately 3-4 in around the sides and 1 in at the entryway.

How do you measure your cat’s step and match the entry height?

This is practical advice from us, not a vet rule. Neither vet source below gives a maximum entry height, so the number that counts is what your own cat manages.

Measure your cat’s length, nose to tail. AAHA/AAFP measure to the tip of the tail; International Cat Care measures to the base of the tail. Use one method for every box you compare.
Measure the lowest step your cat takes now. Find the lowest edge or threshold your cat currently steps over, in or out of its box or across a doorway, without hesitating, and measure its height with a ruler.
Compare it with the entry heights in the table. KittyGoHere publishes 3 in on the Jumbo, and 5 in with its removable gate. A box whose entrance is at or below your cat’s usual step is a sensible place to start.
Where the maker does not publish an entry height, measure it yourself on delivery, before the old box goes. That applies to the Feandrea, the PetFusion BetterBox and the Kitty Sift Large.

Three cautions. The Feandrea’s 11.8 in is the overall height of the box, not the entry; its page says only “low front entrance”. The PetFusion BetterBox’s 8 in is also its overall height, and its page says only “low entry”. And the Kitty Sift high shield lid adds approximately 1 in at the entryway, so measure with the lid on if you plan to use it.

How big should the box be?

AAHA/AAFP recommend a box at least one and a half times the length of the cat from nose to tip of the tail, which they say means most manufactured boxes are not large enough, and that larger storage containers are likely to achieve the right size. International Cat Care puts the ideal length of the tray at one and a half times the length of your cat from nose to base of tail.

Two of the four makers here publish an overall length: Feandrea at 24.4 in and PetFusion at 22.6 in. For the others, check the size when the box arrives against your own measurement.

What do vets say about litter boxes for older cats?

The AAHA/AAFP feline life stage guidelines say the litter box edges “should not be too high in order for a kitten or senior cat to enter and exit easily.” Their rule of thumb is one litter box for each cat plus one additional box, placed in multiple quiet, easily accessible locations.

International Cat Care says open trays with low sides are ideal for older cats, but trial and error will help you find your cat’s preference. If your cat finds stairs difficult, it suggests making sure all of its resources, litter trays included, are on the level the cat uses.

AAHA/AAFP also note that mature adult and senior cats may house-soil secondarily to medical or behavioral conditions, and International Cat Care lists stiffness, limping or difficulty jumping among the signs to watch in senior cats. A different box does not tell you why, so if your cat’s habits have changed, talk to your vet.

How do you choose a low entry litter box for an older cat?

Measure your cat nose to tail and plan for a box at least 1.5 times that length. Use the same method, tip or base of the tail, for every box you compare.
Measure the lowest step your cat takes now, over a threshold or in and out of its current box, without hesitating.
Compare entry heights. Only the KittyGoHere Jumbo publishes one (3 in, or 5 in with its gate). Where the table says “Not published”, plan to measure on delivery before the old box goes.
Check the weight guide. The makers list up to 33 lb (Feandrea) and up to 35 lb (KittyGoHere Jumbo). PetFusion and Kitty Sift do not publish one.
Check the sides. International Cat Care calls open trays with low sides ideal, but preference varies. The Feandrea and the PetFusion BetterBox are open-top boxes, at 11.8 in and 8 in overall height.
Put the box on the level your cat uses, and follow AAHA/AAFP’s rule of one box for each cat plus one additional box.
Keep the old box nearby at first, so you can see how your cat takes to the new one.

How we picked

We didn’t test these litter boxes hands-on. We compared each maker’s published entry height, cat weight guide, size, material and options from its own page, checked on 26 October 2026, and each Amazon listing was checked by hand the same day. Where a maker does not publish a figure, the table says “Not published” and we do not fill it in. Full method: how we choose products.
