Can Red-eared Sliders eat Dieffenbachia?

Why

[confidence: high] [source: ASPCA Toxic Plant Database cross-referenced with exotic reptile veterinary toxicology review (e.g., Mader's Reptile and Amphibian Medicine and Surgery); confirmation via peer-reviewed herpetological veterinary literature on oxalate toxicity in chelonians] Dieffenbachia contains insoluble calcium oxalate raphides that cause intense oral irritation, swelling, and can impair swallowing in red-eared sliders; aquatic turtles are particularly vulnerable as ingestion during foraging in water can lead to rapid mucosal injury. No safe threshold exists for this species.
