No, rabbits should not eat elephant ears (Alocasia or Colocasia plants). Elephant ear plants contain calcium oxalate crystals, which can be toxic to rabbits if ingested. These crystals can cause irritation and burning of the mouth, tongue, and throat, leading to symptoms such as drooling, difficulty swallowing, and potentially more severe reactions.

It's essential to provide rabbits with a safe and appropriate diet consisting of fresh hay, fresh vegetables, limited amounts of pellets specifically formulated for rabbits, and access to clean water at all times. Stick to rabbit-safe foods like leafy greens (e.g., romaine lettuce, kale, spinach), herbs (e.g., parsley, cilantro), and certain vegetables (e.g., carrots, bell peppers) to ensure their health and well-being.

If you suspect that your rabbit has ingested elephant ear plants or any other toxic substance, contact a veterinarian immediately for proper guidance and treatment. It's always better to err on the side of caution and avoid feeding rabbits any potentially harmful plants.
