Is giant chalk dudleya safe for cats and dogs?
Mildly. The ASPCA flags giant chalk dudleya 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. Dudleya brittonii is not individually listed by the ASPCA. The genus Dudleya is in the Crassulaceae family; while most Crassulaceae are mildly toxic (bufadienolide glycosides in some relatives), no confirmed reports of serious poisoning in pets are documented for Dudleya. Treat as mildly toxic as a precaution.
