Is alpine aster safe for cats and dogs?
Mildly. The ASPCA flags alpine aster 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. Aster alpinus belongs to Asteraceae. ASPCA lists some Aster species as causing mild gastrointestinal upset (vomiting, diarrhoea) if ingested by cats or dogs. Contact dermatitis is also possible. Not considered severely toxic but caution is advised.
