Pets are curious creatures, and while we love to see them explore, their curiosity can sometimes lead them to danger. Many common household plants, which might seem harmless, are toxic to cats and dogs. As pet owners, it’s crucial to know which plants pose a risk to ensure our furry companions remain safe. At West Vets Emergency Veterinary Clinic, we handle numerous cases of pet poisoning due to household plants. Let’s explore six common plants that could harm your pet.

1. Lilies

Lilies are beautiful, fragrant flowers that are often used in bouquets and gardens, but they are highly toxic to cats. Species such as Easter lilies, Tiger lilies, Daylilies, and Stargazer lilies pose significant risks. Ingesting even a small amount, including licking the pollen off their fur or drinking water from a vase of lilies, can lead to severe kidney failure in cats.

Symptoms of lily poisoning in cats include:

  • Vomiting
  • Lethargy
  • Loss of appetite
  • Increased thirst and urination (a sign of kidney damage)

If you suspect your cat has been exposed to lilies, time is critical. The faster you bring them to the vet, the better the chances of preventing permanent kidney damage.

Takeaway: If you’re a cat owner, it’s best to avoid lilies entirely, both inside and outside your home. Even a tiny amount can lead to life-threatening conditions.

2. Aloe Vera

Known for its healing properties for humans, aloe vera is a popular houseplant due to its soothing effects on burns and skin irritation. However, aloe vera can be toxic to both dogs and cats when ingested. The plant contains saponins and anthraquinones, which can cause a range of unpleasant symptoms in pets.

Symptoms of aloe vera toxicity include:

  • Vomiting
  • Diarrhea
  • Lethargy
  • Tremors
  • Changes in the color of urine (pink or red)

Though aloe is unlikely to be fatal, it can cause significant discomfort for your pet. If your dog or cat nibbles on aloe, contact your vet for advice on how to proceed.

Tip: Keep aloe vera in areas inaccessible to your pets or consider replacing it with a non-toxic alternative like spider plants or Boston ferns.

3. Sago Palm

Sago palms, despite their attractive appearance, are highly toxic to pets—especially dogs. This plant contains cycasin, a potent toxin that can cause severe liver failure. The seeds (nuts) are the most toxic part, but all parts of the plant are dangerous. Ingesting even a small amount can be fatal.

Symptoms of sago palm poisoning may include:

  • Vomiting
  • Diarrhea
  • Seizures
  • Lethargy
  • Jaundice (yellowing of the skin and eyes)

Note: Symptoms can develop as quickly as 15 minutes after ingestion or may take a few hours. Without prompt treatment, the toxicity can lead to irreversible liver damage or death.

Takeaway: If you have sago palms in your home or yard, consider removing them, especially if you have dogs. This plant is responsible for numerous poisoning cases annually and poses a significant threat.

4. Tulips

Tulips are a spring favorite, bringing bright colors and cheer to many households. However, they can be dangerous to pets, particularly dogs. The most toxic part of the tulip is the bulb, which contains tulipalin A and B, compounds that can cause intense irritation.

Symptoms of tulip poisoning include:

  • Drooling
  • Nausea
  • Vomiting
  • Irritation of the mouth and throat

In severe cases, ingesting a large quantity of tulip bulbs can cause more severe symptoms, such as increased heart rate, difficulty breathing, and even cardiac irregularities. 

Prevention: If you grow tulips in your garden, ensure they are in a location where your pet cannot dig up the bulbs. Consider planting non-toxic alternatives like marigolds or petunias if you have a particularly curious dog.

5. Azalea

Azaleas are commonly found in gardens due to their vibrant blooms and ease of care, but they can be highly toxic to pets. These plants contain grayanotoxins, which interfere with sodium channels in the body, leading to a range of dangerous symptoms if ingested.

Signs of azalea poisoning in pets include:

  • Vomiting
  • Drooling
  • Diarrhea
  • Weakness
  • Low blood pressure
  • Potential coma or death in severe cases

Even consuming just a few leaves can cause severe symptoms. If your pet has been exposed to azaleas, it’s important to seek veterinary care immediately.

Takeaway: Azaleas are best avoided in homes with pets. Safer alternatives include sunflowers or roses, which are non-toxic and still offer beauty to your garden or indoor space.

6. Pothos (Devil’s Ivy)

Pothos, also known as “Devil’s Ivy,” is a popular houseplant thanks to its resilience and ability to thrive in low-light conditions. However, while this plant is easy to care for, it can pose a serious health risk to both cats and dogs if ingested. Pothos contains insoluble calcium oxalates, which cause severe irritation when they come into contact with the tissues of a pet’s mouth and digestive tract.

If a pet chews on or ingests any part of a Pothos plant, symptoms may appear almost immediately. These symptoms include drooling, pawing at the mouth, vomiting, and difficulty swallowing. The plant can cause intense oral irritation, including a burning sensation, which can make pets very uncomfortable. Additionally, swelling of the mouth, tongue, and throat may occur, potentially leading to difficulty breathing if the swelling is significant.

Final Thoughts: Although Pothos is not usually fatal, it is still essential to seek veterinary care if ingestion is suspected. Quick intervention can help alleviate discomfort and prevent complications.

If you believe your pet has ingested any of the above plants, please contact us and seek veterinary care right away.
