Is euphorbia columnaris safe for cats and dogs?
No — euphorbia columnaris is toxic to cats and dogs. Keep it well away from any pet that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. As a Euphorbia, it is covered by the ASPCA's toxic classification for dogs, cats and horses; the toxic principle is the irritant latex sap (diterpene esters). Ingestion or contact causes drooling, mouth and GI irritation and vomiting, and the milky sap blisters skin and severely irritates eyes. Handle with gloves and keep away from pets.
