The Wild Calla, also known as Water Arum or Calla palustris, is a semi-aquatic perennial plant that can pose a toxic threat to cats if ingested. This plant is commonly found in bogs, marshes, and wet soils throughout the northern regions of North America, Europe, and Asia. 

While not as severely toxic as some other plants, the Wild Calla contains insoluble calcium oxalate crystals that can cause irritation and inflammation in cats.

Assessing the Toxicity Level of the Wild Calla Plant

(Level 3-4) - Moderately to highly toxic, ingesting small to moderate amounts can cause severe symptoms

  • Level 1 - Minimally Toxic

    Ingestion may cause mild gastrointestinal upset, but is generally not life-threatening.

  • Level 2 - Mildly Toxic

    Ingestion can result in mild symptoms like vomiting, diarrhea, or drooling. Rarely fatal but may require veterinary care.

  • Level 3 - Moderately Toxic

    Eating these plants can lead to more pronounced symptoms like abdominal pain, lethargy, or difficulty breathing. Veterinary intervention may be necessary.

  • Level 4 - Highly Toxic

    Ingesting even small amounts can cause severe symptoms like organ damage, seizures, or cardiac failure without rapid treatment.

  • Level 5 - Extremely Toxic

    All parts of these plants are extremely poisonous to cats and can quickly lead to death, even with immediate veterinary care.

** Please note: Please note that toxicity level can vary based on the amount ingested and the specific cat. It's always best to keep these plants completely inaccessible to cats and seek immediate veterinary care or call the poison hotline if you suspect your cat has ingested any part of a toxic plant.

Potential symptoms your cat might have

If a cat ingests any part of the Wild Calla plant, it may experience various symptoms due to the presence of insoluble calcium oxalate crystals. These crystals can cause irritation and inflammation in the cat’s mouth, throat, and gastrointestinal tract. Common symptoms include:

  • Excessive drooling
  • Pawing at the mouth
  • Oral irritation and swelling
  • Vomiting
  • Difficulty swallowing
  • Loss of appetite
  • Abdominal pain

In rare cases, if a large amount of the plant is consumed, more severe symptoms such as difficulty breathing or swelling of the airways may occur.
