Is rosemary barberry safe for cats and dogs?
Mildly. The ASPCA flags rosemary barberry 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. Berberis × stenophylla is not individually listed by the ASPCA, but the genus Berberis contains berberine and other alkaloids that are mildly toxic to dogs, cats, and horses if ingested in quantity. The berries can cause gastrointestinal upset; the spines also pose a mechanical hazard.
