The Best Litter Boxes

The best cat litter box is one your cat can step into easily, turn around in, and dig in without kicking litter onto the floor. For most adult cats, that means a large pan with high sides or a covered box with a low entry. Material matters too: stainless steel resists odor better than plastic, while plastic is lighter and costs less.

This list covers open pans, a covered box with a filter, and one pellet system, chosen from published specifications, independent reviews, and Amazon owner ratings. If you would rather stop scooping, see our self-cleaning litter box picks.

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 the Best Litter Box for Your Cat

Size It to Your Cat

A common rule of thumb is a box about one and a half times your cat’s length, measured from nose to the base of the tail. A cramped box can lead a cat to perch on the rim or go elsewhere. Check the listed dimensions, not just the size label: the Petmate Basic on this list is a small 14 by 10.5-inch pan meant for kittens and small cats, while the Tevila XL measures 22.8 by 14.5 inches and is sold for big breeds such as Maine Coons.

Entry Height for Kittens and Senior Cats

Kittens, older cats, and cats with stiff joints do best with a low step-in. Among the open pans here, the Petmate Basic has the lowest walls at 3.5 inches, and the Idymere and Kirecoo pans sit around 5 to 6 inches. Covered boxes with a front door, such as the Nature’s Miracle, are usually easier to enter than top-entry designs, which ask the cat to jump in and out.

Open Pan or Covered Box

A hood holds in scatter and gives shy cats privacy. The trade-off is that odor can build up inside, so a covered box still needs daily scooping. Open pans are easier to scoop and let you see your cat’s urine clumps at a glance. High sides are the middle ground: the Tevila XL adds a 5.7-inch splash guard, and the Arm & Hammer Rimmed box stands 10.6 inches tall for cats that kick hard or urinate high.

Stainless Steel or Plastic

Plastic scratches over time, and those scratches can hold odor. Stainless steel resists that, rinses clean, and lasts longer, which is why three of the seven picks on this list use it. Plastic boxes weigh less and cost less up front; Arm & Hammer suggests replacing its plastic pan every 12 months. For more metal options, see our stainless steel litter box picks.

Homes With More Than One Cat

A common rule of thumb is one litter box per cat plus one extra, placed in different rooms so one cat cannot block another. In a home with three cats, that means four boxes, so floor space and budget both count.

Small Apartments and Shared Rooms

Measure the spot before you order, and leave room for the cat to step in and out. In a studio or a small bathroom, a covered box with a filter or a compact steel pan is easier to live with than a wide open tray. If the box will sit in a living area, litter box furniture can hide it inside a cabinet.

Pellet Systems Are Different

The Tidy Cats Breeze XL is a two-level system, not a plain pan. Urine passes through non-clumping zeolite pellets onto a disposable pad below, and you remove solid waste from the top. Purina says a pad lasts about 7 days for one cat and the pellets last about a month when used as directed, so you will keep buying Breeze pads and pellets. If you want to use the clumping litter you already have, choose a standard pan instead.

Who Should Look Elsewhere

If daily scooping is the problem, a manual box will not fix it. The self-cleaning picks linked above cover models that rake or sift waste into a drawer, though they cost more and need power and floor space.

If your veterinarian has asked you to watch your cat’s urine output, skip covered boxes and pellet systems and use a simple open pan where clumps are easy to see. Browse the full litter box category for more styles.

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 published dimensions, wall height, and entry 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.

Final Thoughts

Best Overall: Nature’s Miracle Hooded Flip Top Cat Litter Box with Charcoal Filter is the box that suits the most homes: a plastic hood that holds in scatter and gives privacy, a front entry most adult cats can step through, a built-in charcoal filter, and a flip-top front so you can scoop without lifting the hood. It is light enough to move for a full clean.

Best Stainless Steel Pick: Kirecoo Large High Sided Stainless Steel Cat Litter Box is an open steel pan with 6-inch sides at 17.5 by 13.6 inches. Choose it if you want a box that will not scratch and hold odor the way plastic can.

Best for Large Cats: Tevila XL Open Top Stainless Steel Litter Box with High Sides measures 22.8 by 14.5 inches, is sold for big breeds such as Maine Coons, and adds a 5.7-inch splash guard for a total height of 10.2 inches, so it holds in litter from cats that dig hard.

Best Budget Pick: Petmate Basic Open Plastic Cat Litter Pan is a plain, low-sided plastic pan. This is the small size, so it fits kittens and small cats, not a full-grown large cat.

Frequently Asked Questions

What size litter box does my cat need?

Measure your cat from nose to the base of the tail. A common rule of thumb is a box about one and a half times that length, with room to turn around and dig.

Is a covered or open litter box better?

It depends on your cat. Covered boxes hold in scatter and give privacy, but some cats dislike them. Open boxes are easier to scoop and let you spot changes in urine clumps.

How many litter boxes do I need for multiple cats?

A common rule of thumb is one box per cat plus one extra, spread around the home rather than lined up side by side.

Is a stainless steel litter box worth it?

For many owners, yes. Steel does not scratch the way plastic does, so it holds less odor over time and lasts longer. Plastic is lighter and cheaper up front.

Why does my cat avoid the litter box?

A box that is too small, too dirty, or in a busy spot is a common reason. Medical problems can also cause a cat to stop using the box, so call your veterinarian if the change is sudden, or if you see straining or blood in the urine.
