Ivy is a genus of 12-15 evergreen climbing vines native to Eurasia and North Africa. They are popular as an ornamental indoor plant as well as a climbing vine or ground cover when grown outside. Mature plants can reach a height of 20-30 metres.
English ivy (Hedera helix) is the most common species of ivy and is found throughout the world. The plant has two stages, juvenile and adult. In the juvenile stage, the leaves are made up of lobed leaves, however, once ivy reaches maturity, the leaves change to an oval shape. Flowers develop on adult plants which form berries in autumn and winter.
The University of California lists the toxicity of ivy as 2 and 4.
2. Minor Toxicity: Ingestion of these plants may cause minor illnesses such as vomiting or diarrhea. If ingested, call the Poison Control Center or your doctor.
4. Dermatitis: The juice, sap, or thorns of these plants may cause a skin rash or irritation. Wash the affected area of skin with soap and water as soon as possible after contact. The rashes may be very serious and painful. Call the Poison Control Center or your doctor if symptoms appear following contact with the plants.
Symptoms can vary depending on the amount of ivy ingested. Most cats will stop consuming ivy quickly due to its unpleasant taste.
- Hypersalivation (drooling)
- Loss of appetite
- Dermatitis (blistering, redness and swelling)
Most cases of ivy ingestion are mild and self-limiting.
To prevent oral irritation, offer the cat something tasty to drink such as milk or tuna juice. Seek veterinary attention of clinical signs such as vomiting and loss of appetite develop.
The only way to prevent ivy toxicity is to keep plants out of the home and grow cat-safe plants.
