Is English Ivy Toxic to Cats?
Also known as: Common Ivy, European Ivy, Hedera Helix · Hedera helix
What makes it toxic
Triterpenoid saponins, mainly hederagenin, in the leaves and berries. They irritate mucous membranes and can cause notable GI inflammation.
Warning signs to watch for
Drooling, vomiting, diarrhea and abdominal discomfort within hours. Skin contact with the sap can cause redness and itching.
What to do if your cat eats it
Remove access and plant material, offer water and call your vet if vomiting recurs or the cat seems uncomfortable. Rinse any sap-exposed skin with mild soap and water.
Common questions
Are the berries worse than the leaves?
Both carry saponins; the leaves are what cats most often chew. Nothing on the plant is safe to eat.
Is English ivy as dangerous as poison ivy?
No. It is not related to poison ivy, but it has its own saponin irritants, so it is not a safe substitute either.
Can English ivy kill a cat?
Fatalities are essentially unheard of. It produces a nasty, dehydrating GI upset rather than organ failure.
