Which houseplants are toxic to cats and dogs?
Every species we track, checked against ASPCA Animal Poison Control. Where we could not resolve an ASPCA entry we say not confirmed rather than calling a plant safe — an unverified "toxic" is a survivable mistake, an unverified "safe" is not.
If your pet has chewed a plant and you are worried, act now, don't read on.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
