Is Gladiola Toxic to Cats?
Also known as: Gladiolus, Sword Lily, Corn Flag, Gladiolus spp. · Gladiolus spp.
What makes it toxic
Unidentified irritant toxins concentrated in the corms (bulb-like underground stems), with milder levels in leaves and flowers. They irritate the digestive tract on ingestion.
Warning signs to watch for
Drooling, vomiting, diarrhea, lethargy and loss of appetite within hours of chewing any part of the plant; corm ingestion produces the most severe signs.
What to do if your cat eats it
Remove plant material, rinse the mouth and offer water. Call your vet if vomiting is repeated or the cat becomes lethargic — and if a dug-up corm was eaten, contact the vet immediately.
Common questions
Are gladiolas as deadly as true lilies for cats?
No — that distinction matters. True lilies (Lilium) cause fatal kidney failure in cats; gladiolas cause painful GI upset but not lily-type kidney failure. Both still warrant a vet call.
My cat dug up the gladiola corms — emergency?
Treat it as urgent. Corms concentrate the toxin, and a cat that eats a whole corm can get severely ill. Call the vet or an animal ER promptly rather than waiting for symptoms.
Is gladiola the same as sword lily?
Yes — sword lily is a nickname for Gladiolus. It is not a true lily, which is exactly why it is far less dangerous to cats than Lilium species.
