Are Calla Lilies Toxic to Cats and Dogs?
You’re arranging a fresh bouquet for your kitchen table and the crisp, sculptural calla lilies catch your eye–classic, elegant, and timeless. But as your cat weaves between your ankles or your dog noses at your shoes, a question nags at you: are calla lilies safe to share a home with your pets? The answer isn’t just a footnote for pet owners; it’s a crucial detail that could affect your furry family’s health.
Are Calla Lilies Dangerous for Cats and Dogs? (Quick Answer)
Calla lilies (Zantedeschia species) are toxic to both cats and dogs. All plant parts–including stems, leaves, and flowers–contain insoluble calcium oxalate crystals, which can cause intense oral irritation, drooling, difficulty swallowing, and vomiting if ingested. While rarely fatal, even small amounts may cause significant discomfort in pets.
What Makes Calla Lilies Harmful to Pets?
The Science: Calcium Oxalate Crystals
Calla lilies don’t rely on scent or color alone for defense. Their toxicity comes from insoluble calcium oxalate crystals, microscopic needle-like structures found in every part of the plant. When a pet chews or bites into the plant, these crystals embed into the tissues of the mouth, tongue, and throat, triggering immediate pain and irritation.
Veterinarian Dr. Emily Tan, DVM, at PetSafe Animal Hospital in Los Angeles explains, “We see cases every spring. The crystals cause a stinging, burning sensation–cats and dogs will paw at their mouths, drool excessively, and sometimes vomit within minutes of exposure.”
What Happens If a Pet Eats a Calla Lily?
Symptoms usually begin suddenly:
- Intense mouth pain
- Drooling and foaming
- Pawing at the mouth
- Vomiting
- Reduced appetite
- Difficulty swallowing
Severe swelling can rarely obstruct the airway, a true emergency. The Pet Poison Helpline reported over 570 calls about calla lily ingestion in 2025 alone, most involving indoor cats nibbling bouquets.
Which Lilies Are Toxic to Pets? (Don’t Get Fooled By Names)
The world of lilies is confusing. Not all “lilies” are created equal, and some are catastrophically worse for pets than calla lilies.
| Lily Type | Toxic to Cats | Toxic to Dogs | Severity | Notes |
|---|---|---|---|---|
| Calla lily | Yes | Yes | Moderate | Oral/mouth irritation, rarely life-threatening |
| True lilies (Lilium)* | Yes | Yes | Deadly for cats | Can cause fatal kidney failure in cats |
| Peace lily (Spathiphyllum) | Yes | Yes | Mild-moderate | Similar irritation as calla lilies |
| Daylily (Hemerocallis) | Yes | Yes | Deadly for cats | Extreme kidney toxicity in cats |
*True lilies include Easter lily, tiger lily, stargazer lily, and Asiatic lily.
“A single bite of a true lily can send a cat into kidney failure, but with calla lilies, we mostly see mouth pain and drooling. Still, keep all lilies out of reach,” says NYC-based florist and veterinary technician Samantha Lu, CCF.
How Much Is Dangerous? And What Should You Do If Your Pet Eats Calla Lilies?
Typical Outcomes
Most cats and dogs recover fully from calla lily exposure if they receive prompt veterinary care. Small pets (under 10 lbs) or those who eat large quantities are at higher risk for severe swelling.
What To Do Immediately
- Gently rinse your pet’s mouth with cool water, if safe to do so.
- Call your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435).
- Bring a sample or photo of the plant for identification.
- Watch for persistent vomiting or difficulty breathing–seek emergency care if you notice these.
Treatment may involve anti-inflammatory medication, fluids, and pain control. Most animals improve within 24-48 hours.
Are Calla Lilies Safe for Pet-Friendly Homes?
Placement and Alternatives
Calla lilies aren’t the most hazardous flower arrangement you could bring home–but they’re far from safe. Even if your pet has never shown interest in houseplants before, curiosity (especially in cats) is a risk factor.
Safer Pet-Friendly Blooms
Florists recommend these beautiful alternatives:
- Roses (without thorns)
- Gerbera daisies
- Sunflowers
- Orchids (Phalaenopsis)
- Snapdragons
If you absolutely love callas, consider high-quality artificial stems from US brands like Afloral or Pottery Barn, starting at $9.99 per stem.
“Silk flowers are having a moment in 2026. You get the sculptural look with zero risk for pets,” adds Chicago event florist Janelle Brooks, AIFD.
How to Keep Pets Away from Toxic Houseplants
Pet parents have gotten creative. Here’s what actually works, according to a 2026 survey of 400 US dog and cat owners by PetMD:
- Physical barriers: Tall plant stands, hanging baskets, or keeping arrangements in closed rooms
- Double-sided tape: Deters cats from tabletops
- Citrus sprays: Cats dislike citrus; dog reactions vary
- Training: Reward-based “leave it” commands for dogs
Still, even with precautions, no live calla lilies are truly safe around pets prone to chewing.
Calla Lilies and Commonly Asked Questions
How toxic are calla lilies to cats and dogs?
Calla lilies cause moderate toxicity in cats and dogs. Effects are mainly in the mouth–burning, swelling, drooling, and vomiting–but severe complications are rare. True lilies (Lilium species), in contrast, are extremely toxic, especially to cats.
What part of the calla lily is poisonous to pets?
All parts are toxic: flowers, stems, leaves, even water from the vase. The highest concentration of calcium oxalate crystals is found in the stems and leaves.
Can pets die from eating calla lilies?
Fatalities are extremely rare. Most pets recover with supportive care. However, large amounts or tiny pets can have more dangerous throat swelling or dehydration from vomiting.
What immediate steps should I take if my pet bites a calla lily?
Rinse your pet’s mouth with water if possible, contact your veterinarian, and monitor for difficulty breathing. Bring a plant sample to the vet for identification.
Are there truly pet-safe lilies?
The only “lilies” considered safe are Peruvian lilies (Alstroemeria) and some species of orchid. Double-check any bouquet with your florist if you have cats or dogs.
Worried about calla lilies and your pets? The safest option is to skip them in both bouquets and landscaping, or keep them well out of reach. If you’re set on their elegant look, opt for high-end faux versions. And the next time you want to bring flowers home, ask your local florist for a “pet-safe arrangement”–it’s become a popular request in 2026, and most US shops are happy to customize for your furry crew.
