The peace lily (Spathiphyllum) is a popular indoor plant known for its elegant white flowers and lush green foliage. However, cat owners should be aware that peace lilies are toxic to cats if ingested. While not as dangerous as true lilies, peace lilies contain insoluble calcium oxalate crystals that can cause oral irritation, drooling, vomiting, and difficulty swallowing in cats.

These plants are commonly found as houseplants or in outdoor gardens in warm climates.

Peace Lily Plant: Toxicity Level Overview

(Level 3) - Moderately toxic, ingesting small to moderate amounts can cause severe oral irritation and other 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.

The Historical Journey of the Peace Lily Plant

The peace lily, native to tropical rainforests of Central and South America, was introduced to Europe in the late 1800s. Its easy care and air-purifying qualities quickly made it popular. Named for its white “flag-like” spathes symbolizing peace, it spread globally as a beloved houseplant.
Today, the peace lily remains a favorite indoor plant worldwide. NASA’s Clean Air Study in the 1980s revealed its exceptional air-purifying abilities, further boosting its popularity. Valued for its lush foliage, elegant white blooms, and low-maintenance nature, it continues to grace homes and offices across the globe.
