Is palo alto sweetgum safe for cats and dogs?
Not entirely — palo alto sweetgum is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's reach. 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. Liquidambar styraciflua is listed by ASPCA as mildly toxic to dogs and cats. The spiny seed pods (gumballs) and sap can cause gastrointestinal irritation if ingested. The resinous sap (storax) may also cause contact dermatitis. Avoid planting where pets or children have unrestricted access to fallen seed pods, which pose an additional physical injury risk from their spines.
