Yes. The ASPCA lists Crown of Thorns (Euphorbia milii) as toxic to pets to cats and dogs. Toxic to dogs and cats. The ASPCA and Pet Poison Helpline flag Euphorbia species (including E. milii) for their irritant milky latex sap, which contains diterpene/phorbol esters; ingestion causes drooling, mouth and gastrointestinal irritation, vomiting and diarrhoea, while sap contact irritates skin and eyes.
