pet toxicity on Peace Lily

Quick answer

If your Peace Lily has pet toxicity, the most likely cause is: Yes. Peace lilies (Spathiphyllum) contain insoluble calcium oxalate crystals in all parts of the plant (leaves, stems, and flowers). When a cat or dog chews on the plant, these microscopic, needle-like crystals embed themselves in the sensitive tissues of the mouth, tongue, and throat. This causes immediate, intense pain and irritation. Note: Peace lilies are only "mildly to moderately" toxic (causing mechanical tissue damage) and are not true lilies (which cause fatal kidney failure in cats).

Start here:

  1. 1. Stop the exposure: If you catch your pet chewing the plant, immediately remove it from their reach.
  2. 2. Soothe the mouth: Gently rinse the pet's mouth with water, or offer a small amount of milk or yogurt. The calcium in the dairy binds to the oxalate crystals and helps ease the burning sensation.
