The Best Litter Boxes for Kittens

The best kitten litter box is a small, open pan with a low entry a young kitten can walk into without climbing. Height matters more than anything else in the first weeks: the picks here range from 2.76-inch sides up to steel boxes with a 3.15-inch front entry, so a kitten can step in, turn around, and dig without help.

This list draws on published specifications, independent reviews, and Amazon owner ratings. It covers basic plastic pans, a starter kit, a 5-pack for several rooms, a collapsible box, and low-entry stainless steel pans that can stay in use as your kitten grows.

This guide is general product information, not veterinary advice. If your kitten has diarrhea, strains in the litter box, or stops using it, contact your veterinarian.

How to Choose a Kitten Litter Box

Entry Height Comes First

A young kitten needs to walk into the box, not jump. Listed heights on this list:

• Amibud stainless steel: 2.76 inches
• GCVOPTON plastic pans: 3 inches
• Qiuma stainless steel: 3.15-inch front entry, with higher sides and back
• Petmate Basic: 3.5 inches
• Nyutu stainless steel: 4 inches
• chuyouan collapsible: 1.9 inches folded, 5 inches expanded

The PAWISE pan is sold as low entry and the RIZZARI box has a textured entry step, but neither listing gives an exact entry height, so check them against your kitten when they arrive.

Size Now and Size Later

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. Kittens grow fast, so a small pan is often a first box rather than a forever box. The Petmate (14 by 10.5 inches), PAWISE (14.5 by 10.5 inches), and GCVOPTON (13.9 by 9.8 inches) pans suit the first months. The Nyutu and Qiuma (both 17.5 by 13.6 inches), chuyouan (17.7 by 13.4 inches), and RIZZARI (17.3 by 13.5 inches, listed for cats up to 13 lb) leave more room to grow into. Once your cat kicks litter hard, taller walls help; see our high-sided litter box picks.

One Box or Several

Kittens do not always make it across the house in time, so a box in each room they spend time in helps during training. The GCVOPTON 5-pack gives you five small pans that also stack for storage. For two or more kittens, a common rule of thumb is one box per cat plus one extra.

Plastic or Stainless Steel

Plastic pans like the Petmate, PAWISE, GCVOPTON, and chuyouan are light and cheap to replace, but plastic can scratch and hold odor over time. The Nyutu, Qiuma, RIZZARI, and Amibud are stainless steel, which makers describe as non-porous and easy to wipe clean, and a steel pan can stay in use after kittenhood. For the full comparison, see stainless steel vs plastic litter boxes.

Starter Kits and Collapsible Boxes

The PAWISE kit bundles a low-entry pan with a scoop, cat toys, and a double food and water bowl, which suits a first-time owner setting up a kitten room. The chuyouan box folds down to a 1.9-inch training height and opens to 5 inches as your kitten grows, and its removable step helps catch litter from paws.

Litter and Placement

Use the same litter your kitten used before it came home, at least at first, and ask your veterinarian if you are unsure what type to use with a very young kitten. Many owners start with an unscented litter. Put the box in a quiet spot away from food and water, and place your kitten in it after meals and naps.

Who Should Look Elsewhere

If your kitten is a large breed or you already have adult cats sharing the box, the smallest pans here will feel cramped quickly; see our best litter box picks for full-size options. Hooded and top-entry boxes are a poor fit for very young kittens, though a covered litter box can work once your cat is older and fully trained.

Call your veterinarian if your kitten has diarrhea, strains, cries in the box, or has not used it for a day. Young kittens can become unwell quickly.

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 material, 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

What size litter box does a kitten need?

Big enough to turn around and dig, with sides low enough to walk over. A common rule of thumb is about one and a half times your cat’s length; plan to size up as your kitten grows.

Is a stainless steel litter box OK for a kitten?

Yes, if the entry is low. The Amibud, Qiuma, and Nyutu list low sides or a low front entry, and steel pans can stay in use after kittenhood.

Should a kitten use a covered or open litter box?

Start with an open box. It is easier to find and enter, and it lets you see what your kitten leaves behind. Move to a covered box later if you want.

How many litter boxes do kittens need?

A common rule of thumb is one per cat plus one extra, and during training a box in each room your kitten uses helps prevent accidents.

How do I get my kitten to use the litter box?

Keep the box close, use the litter your kitten already knows, and place your kitten in it after meals and naps. Do not scold accidents; clean them with an enzyme cleaner.
