10 Common Houseplants Toxic to Cats and Dogs

Houseplants can bring life and color to your home, creating a peaceful and inviting environment. However, if you share your home with cats and dogs, it’s essential to be aware that some of these beautiful plants can be hazardous to their health. Pets, especially curious ones like mine, often chew on plants, which can lead to serious health issues. I realized the importance of knowing which on my houseplants may pose a danger to our pets after my in-law’s dog ate a toxic houseplant while we were dog sitting. Let’s explore ten common houseplants that are toxic to cats and dogs, helping you make informed decisions about the greenery you bring into your home.

1. Aloe Vera

Aloe vera is celebrated for its medicinal properties but can cause vomiting, diarrhea, and lethargy in pets due to saponins and anthraquinones. Keep it out of reach or opt for a non-toxic alternative like haworthia.

2. Philodendron

Philodendrons, also known as Heartleaf Philodendron or Sweetheart Plant, can cause oral irritation, drooling, and difficulty swallowing in pets due to insoluble calcium oxalates. Consider safer options like spider plants or Boston ferns.

3. Peace Lily

“Peace Lilies Kill Kitties” is a phase I was taught growing up. Peace lilies, or Mauna Loa, are harmful to pets, causing mouth burning, drooling, and vomiting. Replace them with cast iron plants, which are safe and easy to care for.

4. Sago Palm

Sago palms, also known as Coontie Palm or Cardboard Palm, are extremely toxic, causing severe liver damage and potentially death. Instead, choose parlor palms, which are pet-friendly and non-toxic.

5. Snake Plant

Snake plants, or Mother-in-Law's Tongue, contain saponins that cause nausea, vomiting, and diarrhea in pets. Opt for the areca palm as a safe and attractive alternative.

6. Dieffenbachia

Dieffenbachia, or Dumb Cane, can cause oral irritation, vomiting, and difficulty swallowing in pets. Choose non-toxic alternatives like the Christmas cactus for a safe and beautiful display.

7. Oleander

Oleander is highly toxic, causing severe vomiting, decreased heart rate, and even death. Avoid it entirely and consider colorful yet safe plants like hibiscus.

8. Pothos

Pothos, also known as Devil’s Ivy, causes mouth irritation and vomiting in pets due to insoluble calcium oxalates. Replace it with Swedish ivy, which offers a similar trailing effect without the risk.

9. Jade Plant

Jade plants, also known as Money Plants, can cause vomiting, depression, and incoordination in pets. Opt for the zebra plant, which is safe and attractive.

10. Tulip

Tulip bulbs are especially toxic, causing gastrointestinal irritation and depression in pets. Daffodils, while also toxic, tend to be less appealing to pets and easier to manage.

While houseplants can greatly enhance the aesthetic and air quality of your home, it’s crucial to consider the safety of your pets when selecting plants. Many common houseplants can pose serious health risks to cats and dogs. By choosing pet-safe alternatives, you can enjoy the beauty of indoor greenery without compromising the well-being of your furry friends. Always research any new plants before bringing them into your home, and consult with your veterinarian if you suspect your pet has ingested a toxic plant. With careful planning, you can create a safe and beautiful environment for everyone in your household.
