Is munstead lavender safe for cats and dogs?
Avoid for a pet household. Munstead Lavender is ASPCA-listed toxic to both cats and dogs; even a small chew can drive a vet visit. Plenty of look-alikes on the non-toxic side of the list — see alternatives below. 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. The ASPCA lists Lavender (Lavandula angustifolia) as toxic to cats, dogs, and horses, with linalool and linalyl acetate as the toxic principles and signs including nausea, vomiting (not in horses), and inappetence. Brief nibbling of the plant typically causes only mild GI upset, but concentrated lavender essential oil poses a greater risk, particularly to cats.
