Can Sulcata Tortoises eat ZZ Plant?

Why

[confidence: high] [source: The Tortoise Table plant database, exotic reptile veterinary toxicology review, and ASPCA toxic plant database cross-referenced for chelonian applicability] ZZ Plant (Zamioculcas zamiifolia) contains calcium oxalate crystals throughout all plant parts, which can cause oral irritation, swelling, and systemic toxicity in Sulcata tortoises. As a strict herbivore with a sensitive digestive system optimized for high-fiber grasses, ingestion of calcium oxalate-laden plants poses a meaningful risk of mucosal damage and calcium metabolism disruption.
