Are Calla Lilies Poisonous to Cats?

Calla lilies (Zantedeschia species) are cherished for their elegant, trumpet-shaped flowers and lush green foliage. They are a popular choice in both indoor and outdoor gardens. Despite their common name, the Calla Lily is not a true lily but belongs to the Araceae family, commonly known as the Arum family. This diverse family includes well-known plants like caladium (angel wing) and monstera (Swiss cheese plant).

Toxicity to Cats

Calla lilies are toxic to cats, according to the ASPCA. They contain compounds that can be harmful to cats if ingested. The primary toxic components are calcium oxalate crystals. These needle-like crystals are found in various plant parts, including the leaves, stems, and flowers. When a cat chews or swallows parts of the Calla lily, these crystals can cause various symptoms.

Symptoms of Toxicity

When a cat ingests Calla lily parts, it may experience the following symptoms:

Oral Irritation: The most immediate effect is irritation of the mouth, tongue, and throat. This can lead to excessive drooling, difficulty swallowing, and oral pain.

Gastrointestinal Distress: Vomiting and diarrhea are common as the cat’s digestive system reacts to the toxins.

Swelling: The calcium oxalate crystals can cause swelling in the mouth and throat, which might make breathing difficult in severe cases.

Lethargy: Affected cats may become lethargic or exhibit signs of discomfort.

Immediate Actions

If you suspect your cat has ingested Calla lilies, it’s crucial to seek veterinary care immediately. The veterinarian may perform a physical examination and may induce vomiting to prevent further absorption of toxins. Treatment often includes supportive care to manage symptoms, such as administering fluids and medications to alleviate pain and discomfort.

Preventive Measures

To protect your feline friends, consider placing Calla lilies in inaccessible areas or choose pet-safe plants for indoor decoration. Being aware of the toxicity of various houseplants can prevent accidental ingestion and ensure a safe environment for your pets.
