Important notes

English Ivy (Hedera helix and related Hedera plants) is a climbing vine often grown indoors, in hanging baskets, or on outdoor walls. It is toxic to cats if chewed or eaten. The leaves are the main concern, and berries are also unsafe. The plant contains triterpenoid saponins, including hederagenin, plus other irritating compounds. In plain terms, these chemicals can irritate the mouth and stomach, leading to drooling, vomiting, diarrhea, and belly pain. Some cats or people may also get skin irritation after repeated contact with the leaves or sap. Most cases involve stomach upset, but a larger amount can cause weakness, wobbliness, or tremors. Keep indoor ivy and cuttings out of reach, and do not let cats chew ivy-covered walls or garden vines. If your cat bites or eats English ivy, remove the plant material and call a veterinarian for advice.

  • Main risk: English ivy leaves contain triterpenoid saponins that irritate the mouth and stomach.
  • Symptoms: Drooling, vomiting, diarrhea, belly pain, and sometimes skin irritation after contact.
  • Higher concern: A larger amount may cause weakness, wobbliness, or tremors.
  • Action: Keep ivy plants and cuttings away from cats and call a vet if chewing or ingestion occurs.
