Cycle 01 paired bench logs with in-home maintenance observations.
Public Test Lab
Pine Litter Test Lab
This hub publishes the benchmark scorecards behind our litter recommendations so readers can inspect the same raw outcomes we use in editorial decisions.
Each format stayed in rotation long enough to expose cleanup drift.
Two pine formats plus clay, silica, and tofu are benchmarked directly in this cycle.
8 published metrics. Method notes live on the testing methodology page.
Why this page exists
The site already explains how we test. This page is where the evidence lives. Instead of hiding behind broad claims like "low dust" or "better for multi-cat homes," the lab publishes the exact benchmark outcomes used to rank each litter format.
This cycle covers five directly benchmarked formats: two pine entries, one clay control, one silica entry, and one tofu entry. Other formats mentioned elsewhere on the site stay in editorial context until they have their own benchmarked row.
Use the scoreboard for a fast read, then drop into the raw matrix and individual scorecards when you need the underlying numbers. If you want the narrative version after reviewing the data, move next to the full comparison guide , the review library, or the pine buying and transition guide.
Fine Pine Granules + Biochar held the room longest before consistent ammonia breakthrough.
Kiln-Dried Pine Pellets kept the mess closest to the box edge.
Silica Crystals produced the least visible dust during pour and scoop tests.
Cycle 01 publishes the raw values for odor hold time, dust, tracking, carry weight, monthly cost, sifting, multi-cat durability, and transition difficulty.
Overall scores, best-fit calls, and page-level recommendations interpret the benchmark set. They are not separate lab variables.
Corn, wheat, and paper appear elsewhere on the site as category context only. They are not scored entries in this benchmark release.
Use the lab as one step in a research workflow
The benchmark set is the evidence anchor, but it should sit beside methodology, category context, and product-level competitor pages rather than replacing them.
Read the protocol
Use the methodology page when you need the scoring definitions, contributor roles, and lab limitations before drawing conclusions from the table.
Open page →Zoom out to categories
Use the comparison guide after the raw matrix to see how the benchmarked formats fit into the wider litter category landscape.
Open page →Go narrower with product pages
Use the review library only after the category call is clear. Product pages add photos and testing notes, but they are not a replacement for the benchmark set.
Open page →Scenario benchmark views
These pages do not use a separate scoring system. Each one remixes the same benchmark set for a distinct decision angle, then shows the tool preset used to turn that angle into setup guidance.

Overall scores are weighted from the full benchmark set. Odor hold time, multi-cat durability, and maintenance performance carry the most influence because they shape day-to-day quality of life more than any single convenience feature.
| Rank | Format | Overall score | Best fit | Main tradeoff |
|---|---|---|---|---|
| #1 | Kiln-Dried Pine Pellets | 80/100 | Households that want low tracking and a fast sawdust-sifting workflow. | Cats already attached to clay needed the longest transition runway. |
| #2 | Fine Pine Granules + Biochar | 80/100 | Readers optimizing for odor control without abandoning a wood-based litter workflow. | A finer texture raises slightly more residue near the mat than large pellets do. |
| #3 | Silica Crystals | 47/100 | Owners who want a light bag and minimal airborne dust. | High monthly spend and weak sifting flexibility hurt long-term value. |
| #4 | Tofu Clumping | 44/100 | Owners who want a plant-based clumping texture closer to clay. | Scatter and stickiness increased after heavy traffic days. |
| #5 | Clumping Clay | 27/100 | Owners prioritizing fast cat acceptance over cleanup burden. | High tracking and bag weight made it the hardest day-to-day format to live with. |
Raw benchmark matrix
Each row below uses the same scoring definitions published in our methodology. Higher is better for odor hold, dust, sifting, and multi-cat durability. Lower is better for tracking radius, carry weight, monthly cost, and transition difficulty.

Format scorecards
These scorecards collect the context that raw tables miss: where a format won, where it broke down, and what kind of home gets the best version of its tradeoff.
Pine
Kiln-Dried Pine Pellets
80
The cleanest maintenance routine in the test set, with low scatter and excellent sifting once the household was comfortable with the texture.

- Best tracking control in the full benchmark cycle.
- Stayed easiest to refresh in sifting boxes after day 10.
Pine
Fine Pine Granules + Biochar
80
The strongest odor performer among the pine formats, trading a little extra floor residue for longer hold time in busy boxes.
- Odor hold
- 33 hr
- Dust
- 8.2/10
- Tracking
- 15 in
- Carry
- 15 lb
- Monthly cost

- Top odor hold time in the cycle.
- Handled multi-cat traffic best among the pine entries.
Silica
Silica Crystals
47
Strong dust control and light carry weight, but the crystal workflow stayed expensive and awkward to sift or refresh selectively.

- 18 in
- Carry
- 13 lb
- Monthly cost
- $31

- Highest clean-air score in the cycle.
- Performed best when owners preferred full-box swaps over top-ups.
Plant-based
Tofu Clumping
44
A balanced middle ground with reasonable dust and weight, but more tracking than pine and less resilience once several cats shared a box.
- Odor hold
- 24 hr
- Dust
- 7.7/10
- Tracking
- 20 in
- Carry
- 14 lb
- Monthly cost
- $29

- 7.4/10
- Transition
- 3.9/10
Best fit: Owners who want a plant-based clumping texture closer to clay.
Watch for: Scatter and stickiness increased after heavy traffic days.
- Easier transition than pine, but not as clean around the box.
- Value weakened once replacement frequency increased.
Clay
Clumping Clay
27
Still the easiest format for cats to recognize immediately, but it lagged badly on dust, carry strain, and floor mess.
- Odor hold
- 20 hr
- Dust
- 5.0/10
- Tracking
- 33 in
- Carry
- 32 lb
- Monthly cost
- $22
- Sifting
- 3.1/10
- Multi-cat
- 8.1/10
- Transition
- 2.1/10
Best fit: Owners prioritizing fast cat acceptance over cleanup burden.
Watch for: High tracking and bag weight made it the hardest day-to-day format to live with.
- Lowest carry-weight convenience score by a wide margin.
- Stayed familiar to cats, but cleanup burden climbed fastest.
