Dogs
Safe in ModerationMildPoinsettia sap can irritate the mouth and cause mild vomiting or drooling in dogs, but it's far less dangerous than its reputation suggests.
Cats

Where the "deadly poinsettia" myth comes from
The belief that poinsettias are lethal to pets is widespread but exaggerated. The plant's milky sap can irritate the mouth, throat and stomach, and may irritate skin or eyes on contact, but serious poisoning is not expected.
Mild plant, bigger holiday risks
A pet that eats a lot of leaves may vomit more, and kittens or very small pets can be more affected. If you want to focus your caution, other seasonal plants such as lilies, mistletoe and holly are considered more dangerous than poinsettia.
Signs to watch for
- Drooling and lip licking
- Vomiting
- Mild diarrhea
- Skin or eye irritation from the sap
Most cases are mild and settle on their own.
What to do
Rinse your pet's mouth gently with water, offer a drink, and wipe any sap from skin or fur. Call your vet if vomiting keeps going, your pet ate a large amount, or you are worried.
Safer alternatives
A Christmas cactus is generally considered a pet-friendlier holiday plant; confirm any plant against the ASPCA's list.
Frequently asked questions
Should I get rid of my poinsettia?
Not necessarily. Place it out of reach, and if your pet is a determined plant chewer, consider a different holiday plant.
Are artificial plants safe?
Plastic and silk plants are not toxic, but swallowed pieces can cause choking or intestinal blockage.
