Is showy autumn crocus safe for cats and dogs?
Toxic — the ASPCA lists showy autumn crocus as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Colchicum speciosum contains very high concentrations of colchicine and related Colchicum alkaloids throughout the entire plant — corm, flowers, leaves, and seeds. The ASPCA lists Colchicum (Meadow Saffron / Autumn Crocus) as toxic to cats, dogs, and horses. Symptoms of ingestion include bloody vomiting, diarrhoea, respiratory failure, kidney and liver damage, bone marrow suppression, and cardiovascular collapse, which can be fatal. There is no antidote. Seek emergency veterinary treatment immediately if any ingestion is suspected. Wear gloves when handling corms as sap can irritate skin and eyes.
