Cats may be poisoned if they eat the leaves of a peace lily (Spathiphyllum). Peace lilies, also known as white palms, belong to the Araceae family, and these plants are generally toxic to cats. If a cat accidentally ingests a peace lily leaf, it may experience symptoms such as vomiting, abdominal pain, drooling, and diarrhea.

Therefore, if you discover that your cat has eaten the leaves of this plant, you should closely observe its behavior and health. If any abnormalities are found, you should contact a veterinarian immediately and inform them of the type of plant it ate so that they can receive professional treatment advice.
