The peace lily (Spathiphyllum) is a popular houseplant prized for its elegant white blooms and lush green foliage. However, its beauty hides a potential danger for cat owners. Peace lilies are toxic to cats, and understanding the risks, symptoms, and preventive measures is crucial for pet safety. This article explores the relationship between peace lilies and cats, addressing symptoms of ingestion, emergency steps, toxicity details, and ways to protect your feline friends.
Peace Lily Cats Symptoms
Symptoms of peace lily ingestion in cats include vomiting, drooling, pawing at the mouth, difficulty swallowing, and decreased appetite.
When a cat consumes any part of a peace lily, it may exhibit signs of poisoning due to calcium oxalate crystals, the plant’s toxic component. Common symptoms include:
- Vomiting: Often one of the first signs as the cat’s body tries to expel the irritant.
- Excessive Drooling: Caused by oral irritation from the crystals.
- Pawing at the Mouth: A reaction to burning or stinging in the mouth and throat.
- Difficulty Swallowing: Due to swelling or discomfort in the oral cavity.
- Decreased Appetite: Resulting from nausea or pain after ingestion.
Symptoms typically appear within a few hours and may range from mild to severe, depending on how much was eaten. Immediate attention is advised if these signs are observed.

What to Do If Cat Eats Peace Lily?
If your cat eats a peace lily, rinse its mouth with water, offer milk or yogurt, and contact a veterinarian immediately.
Acting quickly can minimize harm if your cat ingests a peace lily. Follow these steps:
- Remove Plant Material: Gently clear any remaining pieces from your cat’s mouth if safe to do so.
- Rinse the Mouth: Use a damp cloth or small amount of water to rinse out the mouth, reducing irritation.
- Offer Relief: Give milk, yogurt, or water to dilute the crystals and soothe the mouth (if the cat will drink).
- Call a Vet: Contact your veterinarian or an emergency pet poison hotline (e.g., ASPCA at 1-888-426-4435) right away, even if symptoms seem mild.
- Monitor: Watch for worsening signs like swelling or breathing difficulty, and follow the vet’s advice.
Prompt action can prevent serious complications, so don’t delay seeking professional help.

Are Peace Lilies Toxic to Cats
Yes, peace lilies are toxic to cats due to calcium oxalate crystals, which cause irritation and swelling.
Peace lilies are indeed toxic to cats, though they are not as deadly as some other plants (e.g., lilies from the Lilium genus). The toxicity comes from insoluble calcium oxalate crystals found throughout the plant. When chewed or ingested, these crystals release and penetrate soft tissues, causing immediate irritation. While rarely fatal, the discomfort can be significant, and in rare cases, severe swelling may obstruct breathing. The ASPCA lists peace lilies as toxic to cats, dogs, and horses, confirming their risk to pets.
What Part of Peace Lily Is Poisonous to Cats?
All parts of the peace lily—leaves, stems, flowers, and roots—are poisonous to cats due to calcium oxalate crystals.
Every part of the peace lily contains calcium oxalate crystals, making the entire plant hazardous to cats:
- Leaves: Often the most chewed part, causing oral irritation.
- Stems: Less commonly eaten but equally toxic.
- Flowers: The white spathes may attract curious cats, delivering the same toxins.
- Roots: Rarely accessed but dangerous if dug up and ingested.
No part is safe, so keeping the whole plant out of reach is essential for cat owners.

Peace Lily Cats Dangerous
Peace lilies are dangerous to cats, causing painful irritation and, in rare cases, severe swelling that may affect breathing.
While peace lilies aren’t typically lethal, they pose a real danger to cats. The calcium oxalate crystals cause intense burning and swelling in the mouth, throat, and stomach, leading to distress. In most cases, the effects are limited to discomfort and gastrointestinal upset. However, if a large amount is consumed or swelling blocks the airway (a rare but serious risk), it can become life-threatening. Veterinary intervention can manage these risks, making peace lilies a moderate but notable hazard for cats.
How to Keep Cats Away from Peace Lily?
To keep cats away from a peace lily, place it on high shelves, use deterrents like citrus peels, or opt for cat-safe plants instead.
Preventing access is the best way to protect your cat from a peace lily. Try these strategies:
- Elevate the Plant: Place it on high shelves, hanging baskets, or in rooms cats can’t enter.
- Use Deterrents: Scatter citrus peels, aluminum foil, or double-sided tape around the plant—cats dislike these textures and smells.
- Distract with Alternatives: Offer cat grass or catnip to divert attention from the peace lily.
- Cover the Soil: Add stones or a mesh cover to prevent digging, which might expose roots.
- Choose Safer Plants: If risks persist, replace the peace lily with non-toxic options like spider plants or Boston ferns.
Consistency in these methods ensures your cat stays safe while you enjoy your greenery.
Conclusion
Peace lilies bring elegance to homes but pose a toxic threat to cats due to calcium oxalate crystals in all parts of the plant. Symptoms like vomiting and drooling signal trouble, and quick action—rinsing the mouth and calling a vet—can mitigate harm. While not usually fatal, the danger of irritation and rare severe swelling makes prevention key. By elevating plants or using deterrents, cat owners can enjoy peace lilies safely. Awareness and proactive care keep both pets and plants thriving.
