Moderate Exposure Risk — Why This Product Category Matters

Pets are exposed to the same household chemicals as humans — often at higher concentrations because they spend more time on floors where chemicals settle. Pet food packaging, plastic food bowls, and synthetic pet beds are sources of chemical exposure for pets.

Why We Rated It This Way

Tidy Cats' clumping litter contains added fragrances that can irritate cats' sensitive respiratory systems. Unscented clay litter or natural alternatives (corn, wheat, pine) are safer for cats.
