Is Calla Lily Toxic to Cats?
Also known as: Arum Lily, Pig Lily, Zantedeschia, Trumpet Lily · Zantedeschia aethiopica
What makes it toxic
Insoluble calcium oxalate crystals in leaves, stems and the white spathe. Chewing drives needle-like crystals into oral tissue, causing pain and swelling rather than organ damage.
Warning signs to watch for
Immediate drooling, mouth burning, pawing at the mouth, vomiting and difficulty swallowing within minutes.
What to do if your cat eats it
Rinse the mouth, remove plant material and offer water or milk. Call your vet if drooling and vomiting persist; the kidney-failure emergency applies to true lilies, not this plant.
Common questions
Is calla lily dangerous like an Easter lily for cats?
No. Despite the name, Zantedeschia is an arum, not a true lily. It causes painful mouth irritation but not kidney failure. Still, confirm the species before dismissing any “lily” incident.
Can I tell a calla lily from a true lily by sight?
Calla lilies have one smooth white spathe wrapped around a spike. True lilies have six prominent petals with protruding stamens. If unsure, send a photo to your vet and treat it as an emergency.
