Is Autumn Crocus Toxic to Cats?
Also known as: Meadow Saffron, Naked Lady · Colchicum autumnale
What makes it toxic
Colchicine, a potent antimitotic alkaloid present in every part of the plant and concentrated in the bulbs. It poisons rapidly dividing cells in the gut, bone marrow and kidneys.
Warning signs to watch for
Early drooling, vomiting, diarrhea and bloody stools within hours, followed by kidney failure, bone marrow suppression, seizures and death days later if untreated. Early signs may briefly improve before organ failure begins.
What to do if your cat eats it
Go to an emergency veterinary clinic immediately even if only a leaf or petal was chewed. Tell the vet the plant name; early decontamination and supportive care save lives.
Common questions
Is autumn crocus the same as spring crocus?
No. Spring crocus (Crocus vernus) is mildly toxic at most, but autumn crocus (Colchicum) contains colchicine and is far more dangerous. Both should still be kept away from pets.
Can a cat survive eating autumn crocus?
Survival is possible with very rapid treatment, but delay is often fatal. There is no antidote for colchicine, so emergency care within the first hours is critical.
