Is Poinsettia Toxic to Cats and Dogs?
Poinsettia (Euphorbia pulcherrima) is a common decorative plant, especially during the winter holidays. It is listed as toxic to cats, dogs, and horses by the ASPCA. The plant contains a milky, irritant sap in its leaves, colorful bracts, and stems.
While this popular plant is technically toxic, its effects are generally considered mild. The reputation of the poinsettia as a highly dangerous plant for pets is largely exaggerated. Most interactions result in minor discomfort rather than a serious medical emergency.

What the ASPCA lists for poinsettia
The American Society for the Prevention of Cruelty to Animals (ASPCA) includes the poinsettia in its database of plants that are toxic to cats, dogs, and horses. The organization identifies the toxic principle as an irritant sap.
According to the ASPCA, the clinical signs of exposure are irritation to the mouth and stomach. This can sometimes cause a pet to vomit. The ASPCA’s entry also clarifies that the plant’s toxicity is generally overrated. This means that while ingestion can cause discomfort, severe or life-threatening poisoning from poinsettias is not expected.
What it means for a home with pets
If a dog, cat, or horse chews on a poinsettia plant, the sap can cause discomfort. Your pet might drool or show other mild signs of gastrointestinal upset. Symptoms are typically limited to irritation of the tissues in the mouth and stomach. In some cases, a pet might vomit after ingesting part of the plant.
Because the effects are usually not severe, an accidental nibble is not typically a cause for major alarm. However, every pet can react differently, and the amount consumed can influence the level of irritation.
How to keep pets and this plant apart
The safest way to enjoy poinsettias in a home with pets is to prevent access to them. Place the plants in a room that pets cannot enter or on a high, stable surface that your cat or dog cannot reach. Remember that cats are skilled climbers, so a high shelf may not be enough.
Always supervise pets around new plants. If you notice your pet showing strong interest in chewing the leaves, it is safest to remove the plant from your home. Be sure to sweep up any fallen leaves or colorful bracts promptly to eliminate the temptation for a curious pet to taste them.
When to call your vet
If your pet chewed or ate part of this plant, call your veterinarian or an animal poison control line. Note which plant and which part, how much may be gone and when, and take a photo or a piece of the plant with you.
If your pet has eaten any part of a poinsettia and you are concerned, call your veterinarian or a pet poison hotline like the ASPCA Animal Poison Control Center at (888) 426-4435.

Do not try to induce vomiting or give any home remedies unless specifically instructed to do so by a veterinary professional.
