Are Peace Lilies Poisonous to Cats, Dogs and Kids?
From the Spathiphyllum family, Peace Lilies aren’t true lilies (Liliaceae) and so don’t pack the toxic punch genuine lilies do. This “lily” is really a “rhizomatous herb” from the forests of South America, more closely related to the Anthurium.
Even so, Peace Lilies do contain oxalates which can irritate an animal’s mouth and stomach. Because the irritation begins at first bite, however, the animal stops eating the plant pretty quickly, avoiding severe poisoning. Cats and dogs that ingest Peace Lily leaves begin to salivate profusely, shake their heads and paw at their mouths.
