Is palo santo safe for cats and dogs?
Mildly. The ASPCA flags palo santo as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Bursera graveolens is not individually listed by ASPCA as either toxic or non-toxic. Bursera sap and resins contain terpenoids and can irritate skin and mucous membranes on contact. Ingestion may cause mild gastrointestinal upset. Treat with caution around pets and children; the smoke from burning wood should be used in ventilated spaces only.
