Is spartan cliff stonecrop safe for cats and dogs?
Mildly. The ASPCA flags spartan cliff stonecrop 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. Prometheum (formerly Rosularia) belongs to Crassulaceae subfamily Sempervivoideae. The genus is not individually listed by the ASPCA. Related Prometheum serpentinicum is listed as pet-safe by specialist nurseries, but Prometheum laconicum has no published toxicity data. Treat with caution and keep out of reach of pets and children until confirmed.
