Poinsettia
Euphorbia pulcherrima
Poinsettia (Euphorbia pulcherrima) is a popular holiday plant known for its bright red, pink, or white leaves. While it has a reputation for being highly toxic, it is actually a mild irritant for cats rather than a deadly poison. The hazard comes from the thick, milky sap found inside the plant's leaves and stems. When a cat bites the plant, this sap can irritate the mouth, throat, and stomach. The sap can also bother the skin or eyes if a leaf breaks and touches the cat. Because the sap tastes very bad, cats rarely eat enough to cause a serious problem. A cat that chews on a poinsettia may drool, feel nauseous, vomit, or have diarrhea. They might also lose their appetite or seem a bit tired. If the sap gets into their eyes or on their skin, it can cause redness and irritation. Keep these plants away from pets, clean up any fallen leaves, and contact a veterinarian if your cat eats a large amount, cannot stop vomiting, or shows signs of eye pain.
Important Notes
Main hazard: The milky latex sap in leaves and stems can irritate the mouth, stomach, skin, and eyes.
Symptoms: Drooling, mouth discomfort, vomiting, diarrhea, reduced appetite, or low energy; skin or eye contact may cause redness.
Risk level: Poinsettia is usually mildly irritating, not one of the highly dangerous holiday plants for cats.
Action: Keep the plant out of reach and call a vet if vomiting continues, eye irritation appears, or your cat ate a large amount.
