Is Black Calla Toxic to Cats?

If you're a cat owner, you understand how curious and inquisitive these pets can be. As they explore their surroundings, they may end up nibbling on plants in your home or garden. While some plants are safe for cats, others are toxic and can cause severe health complications. In this article, we'll discuss black calla and its potential impact on your furry friend.

What is Black Calla?

Black calla, also known as Zantedeschia Schwarzwalder, is a herbaceous perennial plant that belongs to the Araceae family. It's native to South Africa and is typically grown as an ornamental plant due to its striking black flowers. Black calla has green, arrow-shaped leaves that can grow up to 18 inches tall and 12 inches wide. Its flowers are cone-shaped and have a velvety texture. The plant blooms from late winter through early summer and can be grown both indoors and outdoors.

Is Black Calla Toxic to Cats?

Unfortunately, black calla is toxic to cats. The plant contains calcium oxalate crystals, which can cause a range of health issues in cats. When ingested, these crystals can trigger oral irritation, burning in the mouth and throat, excessive drooling, nausea, vomiting, difficulty swallowing, and even respiratory complications.

What Should You Do if Your Cat Ingests Black Calla?

If you suspect your cat has ingested black calla, it's essential to take immediate action. Even a small amount of the plant can be toxic to your pet. Here are the steps you should follow:

  • Remove the plant: If you spot your cat eating black calla, remove the plant from their vicinity immediately.
  • Contact your vet: Call your veterinarian and describe the situation. They may ask you to bring your cat in for examination or give you specific instructions on what to do next.
  • Observe your cat: Keep a close eye on your pet and look for symptoms of toxicity. The effects of black calla ingestion can manifest within a few hours of ingestion.
  • Provide supportive care: If your cat shows signs of oral irritation, give them small amounts of water or milk to ease the burning sensation. You can also apply a soothing gel or rinse their mouth to help with the discomfort.
  • Follow your vet's instructions: Your vet may advise you to monitor your cat's symptoms or bring them in for further treatment. Follow their instructions carefully to ensure your pet receives the proper care.

What Other Plants are Toxic to Cats?

As mentioned earlier, black calla is not the only plant that can be toxic to cats. Here are some other plants that can cause harm to your furry friend:

  • Lilies: All members of the lily family are extremely toxic to cats and can cause kidney failure if ingested.
  • Aloe Vera: While aloe vera is known for its medicinal properties, its sap can cause vomiting, diarrhea, and tremors in cats.
  • Chrysanthemums: These ornamental flowers contain pyrethrins, which can cause vomiting, diarrhea, and even seizures.
  • Cyclamen: The bulbs of the cyclamen plant contain a toxic compound that can cause vomiting, diarrhea, seizures, and even death if ingested.
  • Philodendron: This common houseplant contains calcium oxalate crystals, which can cause oral irritation, swelling of the mouth and tongue, and difficulty breathing if ingested.

Conclusion

Knowing which plants are toxic to your cat is crucial to ensure their safety and well-being. If you have black calla in your home or garden, it's best to keep it away from your cat or consider removing it altogether. If your cat has ingested black calla or any other toxic plant, seek immediate veterinary care. Remember, prevention is always better than cure!
