This natural wildflower (Arisaema triphyllum) contains insoluble calcium oxalate crystals called raphites, much like those found in the Philodendron, Diffenbachia, and Dumbcane. 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.
