Who signs the reviews
A name, not a house style. Sage Dean puts hers on the litter reviews here, and the standards below are the ones she works to.
Sage Dean
Head of Customer Experience
Sage worked as a veterinary technician before this. That job is mostly the unglamorous end of cat ownership: the box that smells, the cat that stopped using it, the owner who has already tried four bags and wants somebody to just tell them which one. She reads litter the same way now. Not as a product, as the thing standing between a cat and a mess on the floor.
She signs the reviews because a review with no name on it is worth less. If a number here is wrong, there is a person to take that up with, and the correction goes on the page rather than quietly into the archive.
The rest of the crew stays as roles rather than names: buying and testing the bags, building and maintaining the site, and the editorial pass Sage runs before anything goes live. Anyone can be reached through the site.
How the money and the numbers work
Every litter we score is bought at full retail. The readings behind each score sit on the methodology page, so you can check the protocol rather than take the number on trust.
Purrify, an activated carbon additive you stir into litter you already own, has the same owner as this site. That is a real conflict and we are not going to bury it in a footer. The Purrify review says so beside its score, that score is editorial judgement rather than bench data, and it carries no dust, clumping or ammonia reading because none has been published. Skip that one page if it bothers you. Nothing else on the site leans on it.
What gets covered
17 litters reviewed and 90 head-to-head comparisons, all fed by one shared set of readings so a score means the same thing on every page. Testing ran for about two years, with individual runs lasting 30, 60 or 90 days. Reviews were published between October 2025 and March 2026.
What is actually measured
Dust, clumping, odor and tracking are read off instruments on a bench in a laboratory in Montreal. The day-to-day scoring comes from ordinary homes, living rooms and garages, 38 households and 71 cats across the runs. 16 of the 17 litters have a dust reading and 12 have a clump reading. The gaps are printed as not measured. The whole grid, holes included, is on the test data page.
When a page changes
A retest that moves the answer, new comparison data, or a product that has been reformulated. Each review carries the day it was last tested and the day it was last touched, so you can see how stale it is.
Core principles
- Every litter is bought at full retail price. No maker gets a good word in return for anything.
- Dust, clumping, odor and tracking are weighed or counted before anything is scored.
- A reading nobody took is printed as not measured. It is never filled in with a guess.
- Affiliate money never moves a score, a ranking, or a decision to warn you off.
- A page is rewritten the moment a retest changes the answer.
