Peace lilies are popular houseplants due to their attractive appearance and easy maintenance; however, cat owners should be aware that these plants could pose a risk to their furry friends. As beautiful as they are, peace lilies contain calcium oxalate crystals, which can be mildly toxic to both cats and dogs. This article will discuss the potential impact that peace lily toxicity can have on your feline companion and what you, as a responsible pet owner, should know and do to protect your cat from harm.

When a cat takes a bite or chews on a peace lily, the calcium oxalate crystals are released, causing oral discomfort and potential stomach issues. Symptoms may include oral irritation, intense burning in the mouth, tongue, and lips, excessive drooling, vomiting, or difficulty swallowing. Although peace lilies are not as toxic to cats as true lilies, it’s essential to understand the potential risks and take the necessary precautions to prevent accidents.

To ensure your cat’s safety and well-being, it’s best to keep peace lilies out of reach or consider alternative non-toxic plants for your home. By being aware of the potential hazards that peace lilies pose, you can create a safe and comfortable environment for your beloved pet, ensuring their health and happiness for years to come.

Is Peace Lily Toxic to Cats?

Toxic Chemicals Present

Peace Lilies (Spathiphyllum) are indeed toxic to cats. They contain insoluble calcium oxalate crystals, which are responsible for the toxic effects experienced by cats. Although not as toxic as true lilies, these crystals still pose a significant risk to your feline friend.

Symptoms of Poisoning

When a cat comes into contact with Peace Lilies, they may experience a range of negative symptoms. Key reactions include:

  • Oral irritation
  • Intense burning and irritation of the mouth, tongue, and lips
  • Excessive drooling
  • Vomiting
  • Difficulty swallowing

The severity of these symptoms may depend on the amount of contact or ingestion. Since cats tend to groom themselves, they might ingest the calcium oxalate crystals while trying to clean their paws or fur.

To protect your pet, it’s essential to be aware of these dangers and choose safe, non-toxic plants for your home. Peace Lilies may be beautiful, but the health and safety of your cat should always come first.

How to Prevent Exposure

Protecting Your Peace Lily

To prevent your cat from being exposed to the toxic components of a peace lily, it is essential to keep the plant out of their reach. Place your peace lily in a high or inaccessible location in your home, such as on a tall shelf or in a hanging planter. Additionally, regularly check the area around the peace lily for any fallen leaves, flowers, or pollen. Remove these immediately to prevent your cat from ingesting or coming into contact with them.

Cats are curious creatures, so it’s important to be vigilant and monitor their behavior around plants. You may also consider providing a cat-safe alternative for your feline friend to sniff, chew, or play with.

Alternative Safe Plants

If you’re looking for alternative plants that are non-toxic to cats, here are some options:

  • Spider Plant
  • Boston Fern
  • Areca Palm
  • Maranta (Prayer Plant)
  • Calathea

These plants will not only add beauty and interest to your home, but they will also provide a safer environment for your feline friend. Remember that it is crucial to research any new plants you bring into your home to ensure they are safe for your cat.

In conclusion, to protect your cat from peace lily toxicity, keep the plant out of their reach, monitor their behavior, and consider providing alternative, safe plants. By taking these steps, you can create a harmonious and cat-friendly home environment.

What to Do if Your Cat Ingests Peace Lily

If you suspect that your cat has ingested or been in contact with a peace lily, it’s essential to act quickly to minimize any potential harm. In this section, we’ll discuss the first aid measures to take and the importance of contacting a vet for further assistance.

First Aid Measures

If you find your cat has chewed on a peace lily leaf or has it in their mouth, promptly remove any remaining plant material. The next step is to wash your cat’s paws with cool water to remove any irritants. Be cautious and gentle during this process to avoid any further distress.

Additionally, it’s vital to monitor your cat for any signs of discomfort or illness, such as drooling, vomiting, or difficulty swallowing. These may indicate that your cat has been affected by the peace lily’s toxic properties.

Contacting Your Vet

Once you’ve taken the necessary first aid measures to address the immediate situation, it’s essential to reach out to your veterinarian or an emergency animal hospital as soon as possible. They can offer further advice and professional care to ensure your cat’s well-being.

In some cases, your vet may advise you to induce vomiting to eliminate any harmful substances from your cat’s body. Always follow your veterinarian’s instructions and never attempt to induce vomiting without their guidance.

When you go to the veterinary clinic, be sure to take a sample of the peace lily plant. This will help your veterinarian identify what your cat has ingested and determine the best course of treatment.

Remember that acting quickly and seeking veterinary assistance can make a significant difference in your cat’s recovery from peace lily exposure. While peace lily poisoning is rarely fatal in cats, it’s vital to ensure your pet receives proper treatment and care to minimize any potential damage.


In the end, it is important for cat owners to be aware that Peace Lilies are indeed toxic to cats, with the exposure to calcium oxalate crystals found in the plant leading to various health issues. When a cat chews on the plant, they can experience:

  • Oral irritation
  • Burning of mouth, tongue, and lips
  • Excessive drooling
  • Difficulty swallowing
  • Vomiting
  • Diarrhea
  • Breathing difficulties

Of course, not all lilies are equally toxic, but it is best to err on the side of caution when it comes to protecting feline companions from potential harm. Choosing to keep a home or garden free of these beautiful yet dangerous plants is an essential step in ensuring the safety of not only your own cat, but also those who may visit your outdoor spaces.

If, however, you suspect that your cat has ingested part of a Peace Lily, it is important to seek veterinary care immediately, as prompt treatment can make a significant difference in the outcome for your beloved pet.

Ultimately, it is crucial for cat owners to educate themselves about potentially toxic plants and take necessary precautions when considering plant choices for their home and garden environments. This awareness and vigilance not only keep our feline friends healthier and safer, but also strengthens the bond between pet and owner, building trust and enhancing overall happiness and well-being for both parties.
