| Product | Who it suits | Trade-off |
|---|---|---|
 Dr. Elsey's Ultra Litter | Editorial pick for a litter sold as hard clumping and made for several cats. | The maker directs scooping twice a day, so plan your routine before you buy. |
 World's Best Multiple Cat Unscented | Editorial pick for corn-based clumping litter in bags up to 32 lb. | 'No artificial perfumes' leaves room for natural scent, and the extra plant material is undisclosed. |
 Tidy Cats Free & Clean Unscented | Editorial pick for clay with activated charcoal in large containers. | Charcoal is listed as an ingredient, not a promised result. |
 Fresh News Original and Multi-Cat | Editorial pick for a scented paper-pellet litter if you can do without clumps. | The Original is described as non-clumping, so confirm the Multi-Cat version's other details on the maker page. |
 Purrify | Editorial pairing for any of these litters, scented or not. | It is an additive, so it adds to the scoop routine and does not replace it. |
Dr. Elsey's Ultra Litter
Dr. Elsey's Ultra is an unscented natural clay litter that blends heavy granules with medium grain clay. The maker says it has no perfumes or deodorants and can be used in sifting or mechanical boxes. It lists a 3 to 4 inch depth and scooping twice daily, with waste going in the trash, not the toilet. [1]
World's Best Multiple Cat Unscented
World's Best Multiple Cat Unscented is made from whole kernel US grown corn plus a proprietary natural plant material the maker does not fully name, and has no artificial perfumes. Current sizes are 8, 15, 28 and 32 lb. The maker calls it quick clumping and suggests 2 to 3 inches of depth with daily scooping. [2]
Tidy Cats Free & Clean Unscented
Tidy Cats Free & Clean Unscented is a clumping clay litter with activated charcoal. The maker lists no fragrances and no dyes. It comes in a 14 lb jug, 20 lb jug, 35 lb pail, 40 lb box and a 40 lb bag bundle, so you can pick a size by how you store and carry litter. [3]
Fresh News Original and Multi-Cat
Fresh News Original is recycled-paper pellets with baking soda, sold in 4, 12 and 25 lb bags. A separate Multi-Cat version adds a Fresh Linen scent. [4]
Purrify
Activated carbon granules in bags, and the 120g bag is our suggestion for most homes. Mix two tablespoons gently into fresh litter in each box, and top up whenever a smell returns. [6]

View on PurrifyWhy more cats changes the choice
More cats means more boxes and more scooping, so a litter that is easy to scoop and comes in a size that fits your home matters more. Cornell's Feline Health Center tips advise daily removal of clumps and feces.
[5]Clumping style and scooping routine
Dr. Elsey's, World's Best and Tidy Cats clump, so you lift out lumps as they form. Fresh News Original does not clump, so there are no lumps to lift. Scooping is general care, not a proven fix for odor.
[1][2][3][4]How many boxes
Count first. Cornell's rule of thumb is one more box than the number of cats: three boxes for two cats, five for four.
[5]Scented or unscented in a shared home
Cornell's tips say most cats prefer unscented litter, and three of the four litters here are sold as unscented. Fresh News Multi-Cat is the scented route, and Purrify mixes into either. The Purrify link is an affiliate link, so this site may earn a commission if you buy through it. Treat every pick as editorial judgment from maker pages.
