Toxic — keep away from pets
Yes — daffodils are toxic to dogs and cats, especially the bulbs. They contain lycorine, which causes vomiting, and large amounts can affect the heart.
Daffodils (Narcissus) contain lycorine and other alkaloids, plus calcium oxalate crystals, with the highest concentration in the bulb. Eating the flowers or leaves causes drooling, vomiting and diarrhoea; eating bulbs can cause more serious signs including abdominal pain, a drop in blood pressure, tremors and heart rhythm changes. Like tulips, the bulbs are the big risk because dogs dig them up, and they can be mistaken for onions in the kitchen.
Both dogs and cats. Dogs that raid garden beds or bulb storage are most often poisoned; cats may chew cut stems.
Contact your vet or a poison helpline if your pet has eaten any part, and treat bulb ingestion as urgent. Keep daffodil bulbs out of reach, never store them near onions or pet food, and watch dogs in spring gardens.
