Why
The peace lily (Spathiphyllum) is not a member of the true lily family. It contains insoluble calcium oxalate crystals, like pothos and philodendron, which cause mouth and throat irritation when chewed.
This matters for cat owners: true lilies such as Easter or stargazer lilies can be fatal to cats, while peace lilies generally cause only local irritation. If you are not sure which lily your cat chewed, treat it as an emergency.
How to recognize it
Glossy, dark green lance-shaped leaves surround white, spoon-shaped "flowers", which are actually a modified leaf called a spathe wrapped around a central spike. Despite its name, it is not a true lily.
Signs to watch for
- Drooling
- Pawing at the mouth
- Vomiting
- Difficulty swallowing
What to do
- Rinse the mouth with water and offer a cool drink.
- If you cannot identify the lily with certainty, contact a veterinarian immediately.
- Keep the plant out of reach of pets that chew leaves.
