Is All Euphorbia species Safe for African Fat-Tailed Geckos?

The entire Euphorbia genus is unsafe. All species produce a milky latex sap that is highly toxic and causes severe burns, swelling, and potential blindness on contact with eyes or mouth. The sap sprays when branches break — a realistic risk in an active gecko enclosure. Common dangerous species include: Pencil Cactus (E. tirucalli/Firesticks), African Milk Tree (E. trigona), Dragon Bones, and Poinsettia (E. pulcherrima). No Euphorbia species should be used.
