High Exposure Risk — Why This Product Category Matters

Pets are even more vulnerable to chemical exposure than humans. Dogs and cats spend more time on floors, groom themselves (ingesting whatever is on their fur), and have faster metabolisms that concentrate toxins. Conventional pet products often contain the same toxic chemicals as human products, with even less regulatory oversight.
