So, let’s dive in!

Why are some houseplants dangerous to pets?

Houseplants add beauty and freshness to our homes, but not all of them are safe for our pets. Many houseplants contain toxic substances that can cause a range of symptoms when ingested by dogs and cats. The toxicity of these plants can vary, and some may only cause mild discomfort, while others can be life-threatening.

Toxic properties found in houseplants

Different toxic compounds found in houseplants can harm pets in various ways. Here are some common toxic properties found in certain houseplants:

  1. Insoluble Calcium Oxalates: Plants like philodendron, peace lily, dumb cane, and pothos contain insoluble calcium oxalates. When ingested, these substances can irritate the mouth, throat, and gastrointestinal tract, leading to symptoms such as drooling, vomiting, and difficulty swallowing.

  2. Gastrointestinal irritants: Certain houseplants, including snake plants and weeping figs, emit sap or latex that can cause irritation when in contact with the skin or ingested. Gastrointestinal symptoms like vomiting and diarrhea may occur.

  3. Saponins: Saponins are naturally occurring compounds found in plants like aloe vera. Ingesting saponins can lead to gastrointestinal upset.

  4. Cycasin: Sago palms are particularly dangerous to pets as their leaves and seeds contain cycasin, a toxin that can cause liver failure and even be fatal when ingested.

  5. Anthraquinones: Some houseplants, such as aloe vera, contain anthraquinones. These compounds can cause gastrointestinal upset and, in large amounts, may have a laxative effect.

  6. Furocoumarins: Certain plants, including the fiddle leaf fig, contain furocoumarins. When exposed to sunlight, these compounds can cause skin irritation and increased sensitivity to UV radiation.

It is crucial for pet owners to be aware of these toxic properties and take precautions to prevent their pets from accessing harmful houseplants.

Common toxic houseplants

Now that we understand the toxic properties found in some houseplants, let’s look at a list of common houseplants that are known to be toxic to pets:

  1. Fiddle Leaf Fig (Ficus lyrata)
  2. Philodendron (Philodendron bipinnatifidum)
  3. ZZ Plant (Zamioculcas zamiifolia)
  4. Aloe Vera (Aloe barbadensis miller)
  5. Bird of Paradise (Strelitzia reginae)
  6. Dumb Cane (Dieffenbachia)
  7. Sago Palm (Cycas revoluta)
  8. Peace Lily (Spathiphyllum)
  9. Alocasia (Alocasia macrorrhizos)
  10. Oleander (Nerium oleander) – highly toxic to pets, even in small amounts.

These plants, among others, should be avoided if you have pets in your home. It’s important to note that this is not an exhaustive list, and there are additional houseplants that can be harmful to pets.

Keeping your pets safe from toxic houseplants

To protect your pets from the dangers of toxic houseplants, consider the following measures:

  1. Research and educate yourself: Familiarize yourself with the types of houseplants that are toxic to pets. Use trustworthy sources like the American Society for the Prevention of Cruelty to Animals (ASPCA) and refer to their toxic plant database for comprehensive information.

  2. Create a pet-friendly space: Designate areas in your home where pets are allowed and restrict their access to areas where toxic houseplants are present. Consider using gates or a closed-door system to prevent pets from entering certain rooms.

  3. Choose pet-safe indoor plants: Opt for pet-friendly houseplants that are considered non-toxic to cats and dogs. Examples include spider plants, African violets, Boston ferns, and areca palms. These plants can still cause digestive upset if ingested in large quantities, so it’s essential to monitor your pets’ behavior around them.

  4. Keep toxic plants out of reach: If you can’t part with toxic houseplants and decide to keep them in your home, ensure they are placed in areas that are inaccessible to your pets. Consider using hanging baskets or placing plants on high shelves or window ledges.

  5. Supervise your pets: When introducing new houseplants into your home, monitor your pets’ behavior around them. Some pets may be more curious than others, making it crucial to redirect their attention to appropriate toys and treats.

  6. Provide alternative options: Offer your pets safe and appropriate plants for them to explore and interact with. Cat grass and catnip, for example, can provide stimulating alternatives for cats.

  7. Use deterrence methods: To discourage pets from chewing on plants, you can use deterrent sprays or apply natural substances like diluted lemon juice onto the leaves. It’s important to use pet-safe products and consult with a veterinarian if needed.


In conclusion, while houseplants can enhance our homes, it’s essential to be aware of the potential dangers they can pose to our pets. Toxic properties found in certain houseplants can cause various symptoms in pets, ranging from mild discomfort to life-threatening conditions. By staying informed, choosing pet-safe houseplants, and taking preventive measures, we can create a safe environment for our furry friends. Remember, if you suspect your pet has ingested a toxic plant or is showing concerning symptoms, contact your veterinarian immediately.
