Core Editorial Standards
We Compare Multiple Products
We evaluate over 15+ products across all major categories (clay, corn, wheat, pine, coconut, paper, walnut). We review both affiliate and non-affiliate products to ensure recommendations are based on merit, not revenue.
We Update Content Regularly
All reviews and articles are updated quarterly. We monitor manufacturer changes, new scientific research, and user feedback. Every article explicitly states when it was last reviewed.
We Say Where a Claim Comes From
On health and safety questions we link to the organizations that publish the guidance, such as the Cornell Feline Health Center and the ASPCA, so you can read the source yourself. Where a claim rests on manufacturer documentation or on patterns across owner reviews, we say so on the page instead of dressing it up as research. We do not write "studies show" with nothing behind it.
Independence from Sponsors
While we use affiliate links to fund our research, sponsors never dictate our content, our rankings, or the scores we publish. Read our Commercial Disclosure for full details.
We are honest about our limitations. We run no laboratory and we test no litter ourselves, so every score we publish is our own read of manufacturer specifications, published documentation, and patterns across owner reviews. We say that plainly on every page that carries a score.
