Can Sulcata Tortoises eat Dieffenbachia?

Why

[confidence: high] [source: The Tortoise Table plant database, ASPCA toxic plant database cross-referenced with reptile veterinary toxicology resources, exotic reptile vet review] Dieffenbachia contains insoluble calcium oxalate crystals and proteolytic enzymes that cause severe oral irritation, swelling, and potential airway compromise; ingestion by Sulcata tortoises can lead to drooling, difficulty swallowing, and systemic toxicity. This plant should be kept entirely out of any enclosure housing Sulcata tortoises.
