Can Painted Turtles eat Dieffenbachia?

Why

[confidence: high] [source: Exotic reptile veterinary toxicology review (e.g., Mader's Reptile and Amphibian Medicine and Surgery); ASPCA Animal Poison Control Center plant toxicity database] Dieffenbachia contains insoluble calcium oxalate crystals (raphides) that cause intense oral irritation, edema, and potential airway compromise; ingestion by painted turtles can lead to mucosal injury, excessive salivation, and difficulty swallowing. There is no established safe dose, and the plant is considered toxic across reptile and vertebrate species generally.
