Is Cutleaf Philodendron Toxic to Cats?

As pet owners, it is vital to ensure that our furry friends are safe and healthy. This includes taking precautions when it comes to household plants, as some can be toxic to cats and other pets. One plant that has recently garnered attention regarding its potential toxicity is the cutleaf philodendron. In this article, we will explore whether cutleaf philodendron is toxic to cats, the symptoms of poisoning, and measures to take to keep your cat safe.

What is Cutleaf Philodendron?

Cutleaf philodendron, also known as selloum philodendron, is a popular houseplant that is native to Brazil. It is characterized by its large, glossy, and deeply lobed leaves that can grow up to three feet long. Cutleaf philodendron is often used as an ornamental plant in homes and offices due to its aesthetic appeal and ease of care.

Is Cutleaf Philodendron Toxic to Cats?

Yes, cutleaf philodendron is toxic to cats. According to the American Society for the Prevention of Cruelty to Animals (ASPCA), all parts of the plant contain calcium oxalate crystals, which can cause oral irritation, intense burning, and swelling of the mouth, tongue, and lips. If ingested, these crystals can also cause vomiting, diarrhea, and difficulty swallowing, thereby exacerbating the poisoning.

Moreover, the cutleaf philodendron plant releases an airborne pollen that can irritate the respiratory system of your pets. This can lead to symptoms like sneezing, coughing, and difficulty breathing. In severe cases, it could also trigger an asthma attack, especially in cats that are asthmatic.

What are the Symptoms of Cutleaf Philodendron Poisoning in Cats?

If your cat has ingested or come into contact with cutleaf philodendron, you may notice symptoms such as:

  • Vomiting
  • Diarrhea
  • Hypersalivation (excessive drooling)
  • Pawing at the mouth
  • Difficulty breathing
  • Swelling of the mouth, tongue, and lips
  • A reduced appetite
  • In severe cases, kidney failure or even death if left untreated

It is crucial to take these symptoms seriously and contact your veterinarian immediately if you suspect your cat has been poisoned.

What to do if Your Cat is Poisoned?

If you suspect that your cat has ingested or come into contact with cutleaf philodendron, seek veterinary care immediately. Your veterinarian will likely induce vomiting or provide activated charcoal to bind to the toxins and prevent absorption into the bloodstream. In severe cases, your cat may require hospitalization for supportive care, such as fluid therapy and pain management.

It is important to note that if your cat has ingested a toxic substance, inducing vomiting at home is not recommended unless instructed by your veterinarian. Certain substances, especially those that are acidic, can cause further damage to the esophagus during the vomiting process.

How to Keep Your Cat Safe?

The best way to keep your cat safe from cutleaf philodendron poisoning is to keep it out of reach. Place the plant in an area that is inaccessible to pets, such as a high shelf or a room that your pets cannot access. If you have a curious cat, consider using barriers, such as baby gates or fencing, to keep them away from the plant.

If you have multiple pets, be mindful of where you place the plant. For instance, a small dog may be able to reach the plant even if it is placed on a high shelf, whereas a cat may not.

Another way to keep your cat safe is by providing them with an indoor cat-safe garden. This can include non-toxic plants like catnip, cat grass, and spider plants. Providing your cat with an appropriate alternative can help satisfy their natural urges to chew and play with plants.

Conclusion

Cutleaf philodendron is a beautiful and popular houseplant that can cause significant harm to cats if ingested or come into contact with. The plant contains calcium oxalate crystals that can cause oral irritation, difficulty swallowing, and gastrointestinal issues. It can also cause respiratory problems in pets, especially those with asthma. To keep your cat safe, it is vital to keep the plant out of reach and provide alternative non-toxic plants that your cat can safely enjoy. If you suspect that your cat has suffered from cutleaf philodendron poisoning, contact your veterinarian immediately.
