Before You Buy

Key Buying Factors

01

Clumping Ability

Look for litters that form hard, tight clumps that don't break apart during scooping. This makes daily maintenance easy and extends litter life.

02

Odor Control

Effective odor control prevents ammonia buildup. We prefer litters with natural odor neutralizers or activated charcoal over heavy perfumes that may deter cats.

03

Dust Level

Low-dust formulas are better for cats with respiratory issues and keep the area cleaner. Our picks include options that minimize airborne particles.

04

Tracking

Litters with larger granules or specific textures track less outside the box. We looked for products that reduce scatter.

05

Material Type

Clay litters generally offer superior clumping, while pine pellets provide natural odor control and are biodegradable. Choose based on your cat's preference.

06

Bag Size & Value

For current pricing you can get large bags (35-40 lbs) that last longer. We evaluated cost per use to ensure you get good value.

Living With It

Care, Cost and Maintenance

Scoop Daily

Remove clumps and solid waste at least once a day to control odors and keep the box inviting.

Deep Clean Monthly

Empty the entire box, wash with mild soap and water, and refill with fresh litter. This prevents bacterial buildup.

Maintain Proper Depth

Keep litter at least 3-4 inches deep to allow proper clumping and absorption. Add fresh litter as needed to maintain depth.

Pro tip

If you're using a natural pine pellet litter, we recommend a sifting litter box system. The pellets break down into sawdust when wet, and a sifting box makes separation easy.

Frequently asked questions

What is the best cat litter for multiple cats?
We recommend Dr. Elsey's Ultra Unscented Clumping Clay for its superior odor control and strong clumps. It handles multiple cats well and is affordable.
How often should I change the litter completely?
For clumping litters, a full change every 3-4 weeks is typical. For non-clumping litters, change weekly or as needed. Always follow the box's instructions.
Are pine pellet litters safe for cats?
Yes, pine pellets are generally safe and produce no harmful chemicals. However, some cats may not like the texture, so we suggest a gradual transition.
What litter produces the least dust?
Pine pellet litters like Nature's Logic are virtually dust-free. Among clumping clays, Dr. Elsey's Ultra Unscented has very low dust.
Can I flush cat litter down the toilet?
No, you should never flush any cat litter. It can clog pipes and may contain Toxoplasma gondii, which is harmful to marine life.
