Is sichuan arborvitae safe for cats and dogs?
Not entirely — sichuan arborvitae 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. Not individually listed by the ASPCA, but the Thuja genus contains thujone, which can be toxic if foliage or essential oils are ingested by pets in quantity. Keep away from cats and dogs as a precaution.
