- Veterinary guidance says bigger is better: International Cat Care and the AAHA/AAFP feline guidelines suggest a litter box about 1.5 times your cat’s length, nose to base of tail, and note that most store-bought boxes are too small.
- Top-entry boxes keep scatter down and keep dogs out. The same guidelines warn that kittens, seniors and cats with sore joints need low edges for easy entry, and the AAFP/ISFM guidance says cats are about evenly split on covered versus open boxes.
- Buyer reviews of the boxes below mention less litter on the floor, more room for big cats, and a few fit and durability gripes such as lids that pop off or ridges that hold clumping litter.
- This guide is based on reading customer reviews on Amazon and veterinary advice. We did not test the products ourselves.
A litter box is one of the few cat products your cat uses every day, so the wrong one shows up fast: litter across the floor, a big cat hanging over the edge, or a cat that simply stops using it. Two problems drive most searches for this topic. Some owners want a box that keeps litter and dogs out, which is where top-entry boxes shine. Others have a big cat or several cats and need a much larger pan. Both are covered below, along with the cases where neither is the right call.

Top-entry or high-sided open box?
International Cat Care describes two basic styles, open trays and covered trays, and notes that many cats adapt to a covered tray while some feel vulnerable shut in with only one exit, particularly in a home with other cats. The AAFP and ISFM house-soiling guidelines add that research found cats equally divided in their preference for large covered versus uncovered boxes, and that a cat’s preference may depend more on regular cleaning than on the lid. Open boxes are recommended where possible because they make it easier for you to check and scoop often. A top-entry box is therefore a good fit mostly when scatter, a dog or a toddler is the real problem, and your cat is agile and happy with it.
How we picked these litter boxes
We looked at highly reviewed large, top-entry and high-sided litter boxes on Amazon on October 28, 2026 and read the customer reviews shown on each product page, including the critical ones. We summarize what buyers report in our own words. We have not tested any of these products, and a single review is one cat’s experience, not a guarantee. Most of the reviews we could read were positive, so the cautions in this guide come mainly from veterinary advice. Check the current listing for exact dimensions before you order.
1. Top-entry boxes for scatter and nosy dogs
Reviewers like how discreet it looks, which matters in a small home where the box sits near a dining area, and say litter mostly stays inside or on the lid instead of the floor. Owners of big male cats and of a growing kitten report that the box is sturdy and roomy. Others bought it to keep a dog out of the litter, and one owner says even a three-legged cat learned to use it. One buyer says it worked after two other boxes had to be returned. Because the cat has to jump in and out, it is a better match for healthy adults than for kittens or seniors.

Buyers with two 15-pound cats say the box fits them and that there is much less litter around it. Several like the flat bottom and the deep shape, which makes it easy to pull a liner out and carry it to the trash. The main complaints are about the lid: one reviewer says the hinge-style tabs do not hold and the lid pops off when opened, and another found the lid fit weak, though the cats did not mind. If you want the lid to stay put while you scoop, read the latest reviews first.

This is the metal option, and metal usually costs more than plastic, so check the current listing. Buyers say the stainless surface is easy to scoop and wipe clean, that a big cat has room, and that the ridged lid catches litter from paws. One owner whose cat sprays backward says the fully enclosed shape solved a mess, and several mention it keeps dogs out. The listing is newer, so there is less long-term feedback on durability than for the plastic boxes above.

2. Extra-large open boxes for big cats and multi-cat homes
Buyers with cats from about 17 to almost 20 pounds say this is a real extra-large box, and several with two big cats report much less litter on the floor thanks to the tall sides and plastic guard. It also helps with cats that spray a little. It is lightweight and easy to refill. The downsides: it takes a lot of floor space, one reviewer calls the entry height unsuitable for senior cats, another says clumping litter sticks to ridges inside, and a cat that backs up and lifts its rear may still send urine over the wall.

Reviewers describe sturdy plastic, a roomy pan and high sides that keep scatter low even for enthusiastic diggers. One owner of an anxious older cat says the clear standing space helped her aim, and another uses two side by side for one picky cat. Buyers note that colors vary and one disliked receiving white. Read the listed height before you order, because tall sides that help with scatter also make entry harder for a kitten or an arthritic cat.

Who should skip these
- Kittens and senior cats. AAHA says box edges should not be too high for a kitten or senior cat to enter and exit easily, and International Cat Care says cats with arthritis or reduced mobility do better with lower sides.
- Cats that show stress in a lidded box. International Cat Care notes that some cats feel vulnerable with only one way out, and AAFP/ISFM recommends open boxes whenever possible.
- Any cat that has started going outside the box. Peeing more often, straining or house-soiling can signal illness, so call your veterinarian before blaming the box.
Choosing size, number and spot
The AAHA/AAFP feline guidelines recommend one box for each cat plus one extra, placed in different quiet places so one cat cannot block the others. International Cat Care adds that the tray should be somewhere quiet, away from food and water, and not next to cat flaps or full-length windows. Scoop daily, and wash the box with hot water instead of strong chemicals. Cats also have preferences, so if you buy a new style, put it beside the old one rather than swapping it overnight.

Frequently asked questions
How big should a litter box be?
International Cat Care and the AAHA/AAFP guidelines recommend a box about 1.5 times the length of your cat from nose to base of tail. The AAFP/ISFM guidance adds that many commercial boxes are too small, and that a large storage container is an alternative.
Are top-entry litter boxes good for cats?
It depends on the cat. Some cats use them without a fuss, but veterinary guidance says cats are evenly split between covered and open boxes, and that open boxes are easier to keep clean. Skip them for kittens, seniors and cats with sore joints.
How many litter boxes do I need?
AAHA suggests one box for each cat plus one additional box. The AAFP/ISFM guidance says even a single cat should have two boxes in two separate places.
Will a bigger box stop litter scatter?
Reviewers say tall sides and top-entry lids help, but they do not remove scatter entirely. Many buyers still sweep around the box or add a litter mat.
