Is narrow rib cereus safe for cats and dogs?
Not entirely — narrow rib cereus 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. Cereus stenogonus is not individually listed by ASPCA. The genus Cereus has no documented alkaloid or oxalate toxicity, but the sharp spines pose a physical injury risk to pets and children. Ingestion of cactus flesh may cause mild gastrointestinal upset in sensitive animals. Treat with caution around curious pets.
