Verdict
Peace lilies (Spathiphyllum) contain calcium oxalate crystals similar to pothos and philodendron, causing oral pain and drooling. Importantly, peace lilies are NOT in the Lilium genus and do NOT cause kidney failure like true lilies. The confusion in names causes unnecessary panic, but peace lilies are still irritating and should be kept away from cats.
Symptoms to watch for
- • oral pain
- • drooling
- • swelling of mouth and tongue
- • vomiting
What to do
Rinse mouth, offer cold treats. Contact vet if symptoms are severe. Note: this is NOT the same as true lily (Lilium) poisoning.
