Is monkey puzzle tree safe for cats and dogs?
Not entirely — monkey puzzle tree 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. Araucaria araucana is not individually listed by the ASPCA. Its relative Norfolk Island pine (Araucaria heterophylla) is ASPCA non-toxic to cats and dogs, but this species is not classified, so treat it with caution. The stiff, sharp, spine-tipped leaves are a real mechanical hazard and chewed foliage can cause oral injury and GI irritation. The seeds are a human food. Verify with a vet if a pet ingests any part.
