Introduction to Plant Toxicity
Houseplants bring beauty, calm, and fresh air to our homes and workspaces. But for pet-loving professionals—especially those who work from home or run pet-accommodating businesses—it’s essential to understand the potential risks certain plants can pose to our furry companions.
Common houseplants like pothos, fiddle leaf figs, and the beloved peace lily are frequently found in homes and offices. While visually striking and relatively easy to care for, some can be harmful—or even dangerous—if ingested by pets.
The peace lily (Spathiphyllum spp.) is one such plant: stunning and elegant, it’s also mildly toxic. In this guide, you’ll learn how to enjoy the beauty of peace lilies without compromising the well-being of your pets or small children.
Toxic Compounds and Effects
The Hidden Danger: Insoluble Calcium Oxalates
Peace lilies contain insoluble calcium oxalates—needle-like crystals housed within plant cells. When chewed or ingested, these crystals can cause immediate discomfort and irritation to exposed tissues.
Effects on Tissues
- Oral Irritation: Sharp crystals cause pain and swelling in the mouth, lips, and tongue.
- Gastrointestinal Distress: Nausea, vomiting, and decreased appetite can follow ingestion.
- Swelling: In severe cases, swelling may interfere with breathing or swallowing.
Species at Risk
Cats and dogs are the primary concern, though curious toddlers may also be vulnerable. Fortunately, peace lilies are less toxic than true lilies (Lilium and Hemerocallis species), which can cause kidney failure in cats. Still, caution is warranted.
Symptoms of Poisoning in Pets and Humans
Pet Poisoning Symptoms
- Excessive drooling
- Vomiting
- Pawing at the mouth
- Difficulty swallowing
- Decreased appetite or refusal to eat
Symptoms in Children
- Burning sensation in the lips, tongue, and mouth
- Itching or swelling in the throat
- Localized pain, especially if crystals puncture tissue
- Difficulty breathing (in severe cases)
Onset of Symptoms
Symptoms typically appear within 30 minutes to two hours of ingestion. They may develop faster in smaller pets or young children due to their size and metabolism.
Example Scenario
Imagine a home-office cat knocking a pot onto the floor, scattering peace lily leaves. The cat chews on a leaf fragment and begins drooling excessively and pawing at its face. A quick response and vet consultation can prevent more serious complications.
Safety Precautions and Ideal Placement
Out of Reach, Out of Risk
- Place peace lilies on high shelves not accessible to jumping pets.
- Use hanging planters secured to ceilings or brackets.
- Designate plant zones in rooms where pets are not allowed.
Know Your Pet’s Habits
Cats are notorious for reaching high or climbing shelves, while dogs are generally more ground-bound. An out-of-reach shelf for a dog might be an intriguing jungle gym for a curious cat.
Training & Boundaries
While training can be effective for dogs (“leave it” or scent-repellent sprays), cats are more independent and harder to deter without physical barriers. Use scents like citrus or motion-activated pest deterrents as mild disincentives.
Reduce Risk With Proper Care
Healthy peace lilies shed less leaf debris. To ensure your plant is thriving and less likely to drop hazardous leaves:

Emergency Response and First Aid
Immediate Steps After Ingestion
- Remove any visible plant matter from your pet’s mouth.
- Rinse the mouth gently with clean, cool water—using a damp cloth or a pet-safe rinse.
- Observe for signs of irritation: drooling, swelling, vomiting, or labored breathing.
When to Call the Vet
If symptoms persist more than 30-60 minutes, or if they worsen, contact your veterinarian immediately or reach out to poison control resources.
