The Hurricane plant, also known as the Mexican Breadfruit, Cutleaf Philodendron, and Swiss Cheese plant, contains insoluble crystals of calcium oxalate called raphites. Chewing or biting into the plant releases the crystals which penetrate tissue resulting in injury. When dogs or cats ingest insoluble calcium oxalate-containing plants, clinical signs may be seen immediately and include pawing at face (secondary to oral pain), drooling, foaming, and vomiting. Moderate to severe swelling of the lips, tongue, oral cavity, and upper airway may also be seen, making it difficult to breathe or swallow.
