Oyster Plant

Q: Is Oyster Plant toxic to cats?

Caution: potentially harmful. Oyster Plant (Tradescantia spathacea), also known as Moses-in-the-Cradle, is a houseplant with vivid purple and green leaves. The ASPCA lists Tradescantia as toxic to cats, with dermatitis (skin irritation) as the documented clinical sign. Its sap acts as a contact irritant. If a broken leaf oozes sap onto a cat's skin or fur, it can cause localized redness, itching, or a rash. Chewing the plant may also cause mild mouth or stomach upset in some cats, though skin irritation from sap contact is the harm confirmed by authorities. Because of its colorful leaves, the oyster plant can attract curious cats. It is best to keep it out of reach. If your cat gets sap on its skin, wash the area gently with water to prevent a rash. Contact a veterinarian if your cat eats the plant and any drooling or stomach upset does not improve.
