English Ivy

English Ivy (Hedera helix), also known as Glacier Ivy or California Ivy, is an exceptionally popular evergreen climbing vine widely cultivated as groundcover, indoor hanging baskets, and architectural green walls. Despite its elegant appearance, it is moderately toxic to cats and dogs. The foliage, which is more dangerous than the berries, contains complex chemical compounds known as triterpenoid saponins (principally hederacoside C and alpha-hederin). Saponins act as localized irritants; when chewed, they cause immediate oral burning, excessive drooling (hypersalivation), severe abdominal pain, vomiting, and diarrhea. Skin or paw contact with the plant's sap can also cause mild contact dermatitis or allergic rashes. While rarely fatal, it can cause severe dehydration and gastrointestinal distress. If you suspect your pet has eaten English Ivy, rinse their mouth and skin with cool water, and check out safe vining alternatives like the non-toxic Swedish Ivy.
