Pets are exposed to the same household chemicals as the rest of the family — but with far less body mass and far more surface contact with floors, fabrics, and grooming products. One concern worth calling out specifically: many essential oils that are safe for humans are toxic to cats and dogs. Tea tree oil, eucalyptus, peppermint, clove, cinnamon, and citrus oils can cause serious toxicity in cats and dogs even at low concentrations — which means “natural” or “aromatherapy” pet products are not automatically safe. We vet every product in this collection specifically for pet safety, not just human safety.
