Best Cat Litter Buying Guide

Clumping vs. Non-Clumping

Clumping cat litter forms solid clumps when wet, making it easy to scoop out waste and keep the box fresh between full changes. Most clay-based litters and many natural options offer clumping ability.

Non-clumping litter absorbs liquid but doesn’t form clumps, requiring more frequent full changes and often leading to ammonia buildup. For most households, a quality clumping litter is the best choice for convenience and odor control.

When evaluating clumping strength, look for litters that form firm, tight clumps that don’t break apart during scooping. Our top-rated clumping litters, like those from Dr. Elsey’s and World’s Best, consistently receive high marks from verified buyers for their reliable clumping performance.

Odor Control

Odor control is arguably the most critical feature of any cat litter. Effective litters use a combination of absorption, odor neutralizers, and sometimes fragrances to mask or eliminate smells.

Unscented options are often preferred by cats and owners with sensitivities, while scented litters can provide a fresh scent but may deter picky felines.

For superior odor control, look for litters with activated charcoal, baking soda, or plant-based enzymes. The Fresh Step Advanced Odor Shield and ARM & HAMMER Slide Platinum are excellent examples of litters that use odor-fighting technology to keep litter boxes smelling clean for longer periods.

Dust and Tracking

Low-dust cat litter is essential for cats with respiratory issues and for maintaining a clean home environment. Some clay litters produce significant dust when poured or disturbed, while others are virtually dust-free.

Silica gel and certain natural litters tend to be lower in dust but may track more outside the box.

Tracking refers to litter particles that stick to your cat’s paws and get scattered around the house. To minimize tracking, choose litters with larger granules or those specifically designed to be low-tracking.

Pairing your litter with a good litter mat can also help contain mess. For more tips on managing litter box mess, check out our guide to the best absorbent cat litter.

Material: Clay, Silica, and Natural Alternatives

Clay litter, typically sodium bentonite, is the most common and offers excellent clumping and odor control at an affordable price. However, it is non-biodegradable and can be dusty.

Silica gel litter (crystal litter) is highly absorbent, low-dust, and lasts longer between changes, but some cats dislike the texture.

Natural litters made from corn, wheat, pine, or paper are biodegradable and often low-dust, but their clumping and odor control can vary.

Each material has its pros and cons. For eco-conscious owners, natural litters like World’s Best (made from corn) are a popular choice. If you prioritize maximum odor control and minimal maintenance, silica litters might be worth considering.

Multi-Cat Considerations

Households with multiple cats require a litter that can handle heavier use without breaking down or losing odor control. Multi-cat formulas are typically stronger, with enhanced clumping and odor neutralizers. They also tend to be more economical in larger bag sizes.

When choosing a litter for multiple cats, look for products explicitly labeled for multi-cat use. World’s Best Multiple Cat and Fresh Step Multi Cat are specifically designed to withstand frequent scooping and maintain freshness.

A good rule of thumb is to provide one litter box per cat plus one extra. For more on litter box setup, see our guide to the best litter box.

Price and Value

Cat litter costs can add up, especially for multi-cat homes. While premium litters often offer better performance, there are budget-friendly options that still deliver solid clumping and odor control.

The key is to balance cost with the frequency of changes and the number of cats you have.

Dr. Elsey’s Ultra Unscented, for example, is a top performer at a reasonable price, especially in the 40-pound bag. On the higher end, World’s Best Lavender offers a pleasant scent and long-lasting freshness.

To get the best value, consider buying larger bags or subscribing for regular deliveries.

Frequently Asked Questions

What type of cat litter is best for odor control?

Clay litters with activated charcoal or baking soda, such as Fresh Step Advanced Odor Shield, are highly effective. Silica gel litters also excel at absorbing moisture and odors. For natural options, World’s Best uses corn enzymes to neutralize smells.

The key is to choose a litter with strong clumping and frequent scooping.

Is clumping or non-clumping litter better?

Clumping litter is generally better for convenience and odor control because you can remove waste daily without changing the entire box. Non-clumping litter requires more frequent full changes and can lead to ammonia buildup. Most cat owners prefer clumping formulas for their ease of use.

How often should I change the cat litter?

For clumping litter, scoop daily and do a full change every 2 to 4 weeks, depending on the number of cats and the litter quality. Non-clumping litter should be changed at least weekly.

Always wash the litter box with mild soap and water during full changes to prevent bacteria buildup.

Can I flush cat litter down the toilet?

Only flush litter that is specifically labeled as flushable, such as some natural plant-based litters. Clay and silica litters should never be flushed as they can cause plumbing blockages and environmental harm. Even flushable litters should be disposed of sparingly to avoid septic system issues.

What is the best cat litter for kittens?

Kittens are curious and may ingest litter, so choose a non-toxic, gentle formula. Unscented clumping litters made from natural materials like corn or paper are safe options. Avoid silica crystals or heavily perfumed litters.

World’s Best Comfort Care is a popular choice for kittens due to its soft texture and safety.

How much cat litter should I use?

Fill the litter box with 2 to 3 inches of litter. For clumping litter, this depth allows proper clump formation and prevents waste from sticking to the bottom.

Too little litter leads to poor odor control and mess; too much can cause tracking. Adjust based on your cat’s preferences and the box size.
