What Every Cat Owner Should Know

Cats are curious creatures, and their tendency to nibble on plants can sometimes lead to serious health problems. While having greenery in your home can brighten up your space and purify the air, it's essential to choose plants that are safe for your feline friends. Many common houseplants and garden plants are toxic to cats, and even a small nibble can cause discomfort, or worse, serious health issues.


Here’s a guide to some of the most common plants that are dangerous to cats, along with descriptions of their toxic effects and symptoms to watch for.



  1. Lilies (Lilium and Hemerocallis species)

Toxic parts: All parts, including the petals, leaves, pollen, and even water from a vase containing lilies.


Description: Lilies are beautiful, elegant flowers commonly found in bouquets and gardens. They come in various colours, including white, pink, and orange.


Symptoms: Even a small exposure can cause kidney failure in cats. Symptoms include vomiting, lethargy, drooling, loss of appetite, and increased thirst or urination. If left untreated, it can be fatal. Note: Popular types like Easter lilies, tiger lilies, and Asiatic lilies are all highly toxic to cats.

 

  1. Dieffenbachia (Dumb Cane or Leopard Lily)

Toxic parts: All parts of the plant.


Description: Dieffenbachia is a popular houseplant with large green leaves that have white or yellow patterns.


Symptoms: Chewing on this plant can cause irritation of the mouth and tongue, excessive drooling, vomiting, difficulty swallowing, and in severe cases, difficulty breathing due to throat swelling.


 

  1. Sago Palm (Cycas revoluta)

Toxic parts: All parts, but the seeds (nuts) are the most toxic.


Description: This decorative palm has a thick trunk and feathery leaves, often used as an ornamental houseplant.


Symptoms: Ingestion can cause severe liver damage. Early signs include vomiting, diarrhea, and lethargy. Without treatment, symptoms progress to seizures, jaundice, and liver failure, which can be fatal.

 

  1. Pothos (Epipremnum aureum)

Toxic parts: All parts of the plant.


Description: Pothos, also known as Devil’s Ivy, is a hardy, trailing plant with heart-shaped green leaves often streaked with white or yellow.


Symptoms: Mild to moderate toxicity includes drooling, oral irritation, vomiting, and difficulty swallowing.


 

  1. Azaleas and Rhododendrons

Toxic parts: All parts of the plant.


Description: These flowering shrubs produce vibrant blooms in shades of pink, red, white, and purple, commonly seen in gardens.


Symptoms: Ingestion can cause vomiting, diarrhea, excessive drooling, loss of appetite, and in severe cases, abnormal heart rate, low blood pressure, or coma.


 

  1. Tulips

Toxic parts: The bulb is the most toxic part, but all parts can cause issues.


Description: Tulips are springtime favorites with brightly colored cup-shaped flowers.


Symptoms: Drooling, vomiting, diarrhea, and in severe cases, depression and convulsions.


 

  1. Aloe Vera

Toxic parts: The gel is generally safe, but the latex (yellow substance under the skin) is toxic.


Description: Aloe is a popular succulent known for its thick, fleshy leaves filled with gel, often used for its medicinal properties.


Symptoms: Vomiting, diarrhea, lethargy, and changes in urine colour.


 

  1. Peace Lily (Spathiphyllum)

Toxic parts: All parts of the plant.


Description: A common houseplant with dark green leaves and white, flower-like spathes.



Symptoms: Drooling, oral irritation, vomiting, and difficulty swallowing. Peace lilies are less dangerous than true lilies but still pose a risk.


 

What to Do if Your Cat Ingests a Toxic Plant

If you suspect your cat has ingested a toxic plant, take these steps:


  1. Remove the plant: Take it away from your cat to prevent further ingestion.

  2. Check for symptoms: Observe your cat for signs of poisoning, such as vomiting, drooling, lethargy, or changes in behaviour.

  3. Contact your veterinarian immediately: Provide details about the plant and the symptoms you’ve observed.

  4. Call a poison control hotline: The Australian Animal Poison Hotline (1300 869 738) https://animalpoisons.com.au/ is a valuable resource for emergencies.
