Can Red-footed Tortoises eat ZZ Plant?

Why

[confidence: high] [source: The Tortoise Table plant database, exotic reptile veterinarian review, and ASPCA Toxic Plant List cross-referenced for oxalate-bearing aroids] ZZ Plant (Zamioculcas zamiifolia) contains calcium oxalate crystals throughout all plant tissues, which can cause oral irritation, swelling, and gastrointestinal distress in Red-footed Tortoises; systemic oxalate toxicity is also a concern with significant ingestion. All parts of the plant are considered toxic and should be kept away from tortoises entirely.
