Is English Ivy toxic to pets?
English Ivy is considered toxic to household pets including cats, dogs, and horses. The plant contains triterpenoid saponins, particularly hederagenin, which are concentrated most heavily in the leaves and berries. Ingestion by pets can lead to a variety of clinical symptoms such as severe gastrointestinal irritation, vomiting, excessive drooling, abdominal pain, and diarrhea. In rare or severe cases, contact with the sap can also cause localized skin irritation and dermatitis. Pet owners should keep this plant completely out of reach or avoid growing it indoors where animals might chew on the trailing vines.
