Cat litter is a daily purchase, and the label can say a lot of things. This guide covers the main types of litter, how to set up litter boxes, and how the word “organic” is used on litter, then compares five litters by ingredients and bag size.
Disclaimer: This article is general information, not veterinary or medical advice. Ask your veterinarian about your cat’s health, and ask your doctor about toxoplasmosis if you are pregnant or have a weakened immune system.

Litter box safety
  • Scoop the litter box daily.[4] Toxoplasma from cat feces is not infectious until 1 to 5 days after it is shed, so daily cleaning lowers the risk.[5]
  • If you are pregnant, have someone else change the litter box. If you must clean it, wear disposable gloves and wash your hands with soap and warm water afterwards.[5]
  • Wash the box with hot water and avoid strong chemicals, since some cats are sensitive to dirty boxes.[4]

Types of Cat Litter

  • Clumping Litter – Clumping litter is clay mixed with sodium bentonite, which swells and binds into a clump when it gets wet. The clump can be scooped out, and the rest of the litter stays in the box.
  • Non-Clumping Litter – Non-clumping litter is mostly clay with calcium bentonite, which absorbs liquid but does not form a clump. You cannot scoop out the waste alone, so the whole box has to be emptied and cleaned.
  • Plant-based Litter – Litter made from plant or recycled materials such as walnut shells, corn, wheat, pine and paper is often sold as natural litter.

Setting Up and Using Litter Boxes

  • Number of Litter Boxes – Provide one litter box for each cat, plus one extra.[3]
  • Placement of Litter Boxes – Cats like a quiet spot that is not cornered, where they can see people or other animals approaching and leave quickly. The box should be easy to reach at all times.[3] Keep it away from noisy areas and food.
  • Quantity of Litter – Cats usually prefer one to two inches of litter in the box.[3]
  • Size of the Box – A box should be at least one and a half times the length of the cat from nose to tail tip, which means many store-bought boxes are too small.[4]

What to Look for in Cat Litter

  • Odor Control – A litter that absorbs well helps, but scooping daily matters just as much.[4]
  • Clumping or Non-Clumping – Many cats prefer clumping, unscented litter.[3] For a cat with a history of urinary problems, unscented clumping litter may be preferred, so ask your veterinarian.[4]
  • Size and Texture – Soft litter is easier on a cat’s paws. Medium-sized grains tend to stay in the box instead of spreading around the house.

What the Research Says

The USDA organic seal is used on agricultural products such as food, and honey, mushrooms and pet food can be certified.[1] None of the five litters here is sold with a USDA organic claim in its product details, so the ingredient list matters more than the word “natural” or “eco”. Under the FTC’s Green Guides, a “biodegradable” claim without qualification should only be made if the entire product fully breaks down within one year.[2] Veterinary guidelines recommend scooping daily, a box at least one and a half times the cat’s length, and unscented clumping litter for cats with a history of urinary problems.[4]

How We Chose These Products

We do not test products. We compare product details: litter material, clumping or not, scent, bag size and weight, and dust level. Brands don’t pay to be included, though we may earn a commission from purchases.
