Why are pothos toxic to pets?

Answered by Michael Wilson

I’ve had personal experience with the toxicity of pothos plants to pets, and let me tell you, it’s not a pleasant situation. Pothos plants, scientifically known as Epipremnum aureum, are toxic to pets, including cats and dogs. The reason behind their toxicity lies in the presence of insoluble calcium oxalate crystals, which are also found in other plants in the Araceae family.

When a pet chews or bites into a pothos plant, these crystals are released. These tiny crystals are sharp and can cause tissue penetration and irritation in the mouth and gastrointestinal tract of the animal. This can lead to various symptoms and discomfort for our furry friends.

One of the most common signs of pothos toxicity in pets is oral irritation. Pets may experience drooling, pawing at the mouth, and increased swallowing. They may also show signs of discomfort, such as pawing at their face or rubbing their mouth on objects. In severe cases, swelling of the lips, tongue, or throat can occur, making it difficult for the pet to breathe.

Ingesting a significant amount of pothos plant material can also cause gastrointestinal issues in pets. This can manifest as vomiting, diarrhea, and abdominal pain. In some cases, the pet may also show signs of lethargy, loss of appetite, and dehydration.

It’s important to note that the severity of the symptoms can vary depending on the amount ingested and the individual pet’s sensitivity. Some pets may only experience mild irritation, while others may have a more severe reaction.

If you suspect that your pet has ingested or come into contact with a pothos plant, it’s crucial to seek veterinary attention immediately. The vet will be able to assess the situation and provide appropriate treatment. In some cases, supportive care, such as administering fluids or medications to alleviate symptoms, may be necessary.

Prevention is always better than cure when it comes to pet toxicity. If you have pets in your household, it’s advisable to keep pothos plants out of their reach. Place them in areas where pets cannot access them, such as high shelves or hanging baskets. Additionally, consider using pet-friendly alternatives for indoor plants to ensure the safety of your furry companions.

Pothos plants are toxic to pets due to the presence of insoluble calcium oxalate crystals. Chewing or biting into these plants can release these crystals, causing tissue penetration and irritation in the mouth and gastrointestinal tract. It’s essential to be aware of the potential dangers and take necessary precautions to keep our pets safe from pothos toxicity.
