Is Arum Lily Toxic to Cats?

Cats are beloved companions to millions of people worldwide. As a result, pet owners strive to ensure that their furry friends are happy, healthy, and well-cared for. One aspect of cat care that is often overlooked is the safety of the household environment. While most people are aware of the dangers of certain foods, such as chocolate and grapes, many do not realize that certain plants can also be toxic to cats. One such plant is the arum lily. In this article, we will explore whether the arum lily is toxic to cats, why it can be dangerous, and what pet owners can do to keep their feline friends safe.

What is Arum Lily?

The arum lily (Zantedeschia aethiopica) is a popular ornamental plant that is native to South Africa. It is commonly used in gardens and as a cut flower in bouquets. The plant has striking white, trumpet-shaped flowers that bloom in the summer. It is also known by several other names, including calla lily, trumpet lily, and pig lily.

Why is Arum Lily Dangerous?

While the arum lily is a beautiful plant, it can be quite dangerous to cats. The most toxic part of the plant is the rhizome, which is the underground stem that stores nutrients and water. The rhizome contains a chemical compound called calcium oxalate, which can cause severe irritation and inflammation when ingested. If a cat ingests any part of the plant, it can lead to a range of symptoms, including:

  • Vomiting
  • Salivation
  • Mouth and throat irritation
  • Difficulty swallowing
  • Difficulty breathing
  • Swelling of the tongue, lips, and mouth
  • Renal failure (in severe cases)

If left untreated, these symptoms can be life-threatening for cats. It is essential for pet owners to be aware of the dangers of arum lilies and to keep them out of their home.

What to Do if Your Cat Ingests Arum Lily?

If you suspect that your cat has ingested any part of an arum lily, it is crucial to seek veterinary care immediately. Your veterinarian may induce vomiting to remove the plant material from your cat's stomach or use activated charcoal to prevent absorption of the toxic compounds. In severe cases, your cat may require hospitalization and supportive care, such as intravenous fluids and medications to manage pain and inflammation.

How to Keep Your Cat Safe?

The best way to keep your cat safe from arum lilies is to keep them out of your home and garden. If you have arum lilies in your garden, it is essential to keep them out of reach of your pets. You should also be cautious when bringing cut flowers into your home, as many florists include arum lilies in their bouquets.

If you suspect that your pet may have ingested any toxic plants, it is always best to err on the side of caution and seek veterinary care. Your veterinarian can help identify the plant and provide appropriate treatment to prevent any potential harm to your pet.

Conclusion

Arum lilies are beautiful plants that are commonly used in gardens and as cut flowers. However, the plant contains a toxic compound that can be dangerous to cats. If your cat ingests any part of an arum lily, it can cause a range of symptoms, including vomiting, salivation, and difficulty breathing. It is essential to seek veterinary care immediately if you suspect that your pet has ingested any poisonous plants. To keep your cat safe, it is best to avoid having arum lilies in your garden or home and to be cautious when bringing cut flowers into your home.
