Is Cordatum Toxic to Cats?

As cat owners, we always want to ensure the safety and well-being of our feline friends. It is important to be aware of any potential toxins that could harm our pets. Cordatum, also known as Heartleaf Philodendron, is a common household plant with attractive dark green leaves and heart-shaped appearance. However, the question arises whether this plant is toxic to cats or not.

The Toxicity of Cordatum

Cordatum is toxic to cats. The plant contains insoluble calcium oxalate crystals in its leaves, stems, and roots. These crystals can cause severe irritation and inflammation to the tissues of the mouth, throat, and digestive system when ingested. The severity of symptoms can vary depending on the amount ingested and the cat's sensitivity to the toxins.

Some of the common signs of cordatum toxicity in cats include:

  • Swelling and redness of the lips, tongue, and mouth
  • Difficulty in breathing and swallowing
  • Vomiting and diarrhea
  • Excessive drooling and pawing at the mouth
  • Decreased appetite and weight loss

Treatment for Cordatum Toxicity

If you suspect that your cat has ingested cordatum, it is crucial to seek veterinary attention immediately. Your veterinarian may induce vomiting or provide activated charcoal to absorb any remaining toxins in the digestive system. Antihistamines or corticosteroids may also be given to relieve the inflammation and irritation in the mouth and throat.

In severe cases, where the cat is experiencing difficulty in breathing or swallowing, a tracheostomy or feeding tube may be necessary to ensure proper oxygenation and nutrition.

What to Do if Your Cat Ingests Cordatum

Prevention is always better than cure. The best way to prevent cordatum toxicity is to keep the plant out of reach of your cat. If you suspect that your cat has ingested cordatum, it is essential to act immediately. Here are some steps you can take:

  1. Remove any remaining plant material from your cat's mouth, if possible.
  2. Do not induce vomiting unless instructed to do so by your veterinarian.
  3. Contact your veterinarian immediately for advice and to schedule an appointment.
